6 Motion Control Valves Section Contents This section contains a most extensive range of overcenter and motion control cartridges, including normal, part vented and fully vented versions. Suitable for load holding, load safety and to prevent load runaway, giving low pressure drops, various pilot ratios and excellent stability to all types of moving loads. Adjustments The adjustment range and Max setting figures shown throughout this catalogue give the design range for each valve, higher or lower values may be attainable but should not be used without first contacting our Engineering department. Setting must ALWAYS be carried out using an appropriate gauge and it must NOT be assumed that screwing an adjuster to its imum or minimum position will yield the imum or minimum stated design setting for that valve.

8 CE - Overcenter Valve Pilot assisted relief with check L/min (5 USgpm) 7 bar (4 psi) Sectional View Operation The check section allows free flow into the actuator then holds and locks the load against movement. The pilot assisted relief valve section will give controlled movement when pilot pressure is applied. The relief section is normally set to open at a pressure at least. times the imum load induced pressure but the pressure required to open the valve and allow movement depends on the pilot ratio of the valve. or optimization of load control and energy usage, a choice of pilot ratios is available. The pressure required to open the valve and start actuator movement can be calculated as follows: Pilot Pressure = (Relief Setting) - (Load Pressure) eatures Cartridge is economical and fits simple cavity. Allows quick, easy field service - reduces down time. Interchangeable with pilot check valve of a similar size. : Best suited for extremely unstable applications such as long booms or flexible frameworks. 4.5: Best suited for applications where load varies and machine structure can induce instability. 8: Best suited for applications where the load remains relatively constant. Pilot () Valve () Cyl () Description Overcenter valves give static and dynamic control of loads by regulating the flow into and out of hydraulic actuators. When installed close to or within an actuator, the overcenter valve will stop runaway in the event of hose burst and if open center directional control valves are used, will allow thermal expansion relief of the hydraulic fluid. The overcenter cartridge is ideal for mounting directly into a cavity machined in the body of the cylinder, motor or rotary actuator. The cartridge can also be mounted directly to the ports via a specifically machined body as part of a Hydraulic Integrated Circuit or single unit, or contained within one of our standard line bodies. Single overcenter valves are normally used when the load is unidirectional, for example an aerial platform or crane and dual overcenter valves are used for controlling loads in both directional for motor applications or for cylinders going over center.

18 CEB - Overcenter Valve ully balanced, pilot assisted, relief with check L/min (8 USgpm) 7 bar (4 psi) Sectional View Vent Pilot () Valve () Cyl () Description Overcenter valves give static and dynamic control of loads by supplying a counterbalance pressure to the actuator. They prevent runaway in the event of hose burst and hold the load with minimal leakage. The pressure balanced valve is unaffected by back pressure, allowing service line reliefs to operate and for the valve to be used in regenerative or proportional valve systems.

24 CPBD - Overcenter Valve Zero differential with check L/min (8 USgpm) 5 bar (5 psi) 4 Sectional View Operation The check section allows free flow into the actuator then holds and locks the load against movement. By the application of pilot pressure to the pilot port the poppet moves back against the main spring opening the cylinder port to the valve port. The metering characteristic of the valve is controlled by the rate of the spring, the seat angle and the pilot pressure applied. Due to the balanced poppet design load induced pressure will not open the valve and once open valve port pressure will not increase the pilot pressure required to keep the valve open eatures The cartridge fits a simple cavity allowing quick, easy field service reducing down time. Hardened poppet and seat provide for long leak free performance. Performance Data Vent (4) Pilot () Valve () Cyl () Description Zero differential overcenter valves give static and dynamic control of loads by supplying a restriction to flow related to the opening of the valve created by the pilot pressure. The valve is used in conjunction with a remote pilot source to provide hose failure protection, load control and load holding functions. If over-pressure or shock pressure protection is required then a separate relief valve should be used The drain line allows the valve to be used in corrosive atmospheres preventing the ingress of atmospheric contaminant.

42 CPBD9 - Overcenter Valve Zero differential with check 9 L/min ( USgpm) 5 bar (5 psi) 4 Sectional View Operation The check section allows free flow into the actuator then holds and locks the load against movement. By the application of pilot pressure to the pilot port the poppet moves back against the main spring opening the cylinder port to the valve port. The metering characteristic of the valve is controlled by the rate of the spring, the seat angle and the pilot pressure applied. Due to the balanced poppet design load induced pressure will not open the valve and once open valve port pressure will not increase the pilot pressure required to keep the valve open. s The cartridge fits a simple cavity allowing quick, easy field service reducing down time. Hardened poppet and seat provide for long leak free performance.

50 CPBD - Overcenter Valve Zero differential with check 8 L/min (47 USgpm) 4 bar (58 psi) 4 Sectional View Operation The check section allows free flow into the actuator then holds and locks the load against movement. By the application of pilot pressure to the pilot port the poppet moves back against the main spring opening the cylinder port to the valve port. The metering characteristic of the valve is controlled by the rate of the spring, the seat angle and the pilot pressure applied. Due to the balanced poppet design load induced pressure will not open the valve and once open valve port pressure will not increase the pilot pressure required to keep the valve open. eatures The cartridge fits a simple cavity allowing quick, easy field service reducing down time. Hardened poppet and seat provide for long leak free performance.

The valve is used in conjunction with a remote pilot source to provide hose failure protection, load control and load holding functions. If over-pressure or shock pressure protection is required then a separate relief valve should be used.

66 CPBD - Overcenter Valve Zero differential with check L/min (8 USgpm) 4 bar (58 psi) 4 Sectional View Operation The check section allows free flow into the actuator then holds and locks the load against movement. By the application of pilot pressure to the pilot port the poppet moves back against the main spring opening the cylinder port to the valve port. The metering characteristic of the valve is controlled by the rate of the spring, the seat angle and the pilot pressure applied. Due to the balanced poppet design load induced pressure will not open the valve and once open valve port pressure will not increase the pilot pressure required to keep the valve open. eatures The cartridge fits a simple cavity allowing quick, easy field service reducing down time.

DuPont Description Zero differential overcenter valves give static and dynamic control of loads by supplying a restriction to flow related to the opening of the valve created by the pilot pressure. The valve is used in conjunction with a remote pilot source to provide hose failure protection, load control and load holding functions. If over-pressure or shock pressure protection is required then a separate relief valve should be used.

The pilot assisted relief valve section will give controlled movement when pilot pressure is applied. The relief section is normally set to open at a pressure at least. times the imum load induced pressure but the pressure required to open the valve and allow movement depends on the pilot ratio of the valve. or optimization of load control and energy usage, a choice of pilot ratios is available. The pressure required to open the valve and start actuator movement can be calculated as follows Pilot Pressure = (Relief Setting) - (Load Pressure) eature Cartridge is economical and fits simple cavity. Allows quick, easy field service - reduces down time. Interchangeable with pilot check valve of a similar size. 4: Best suited for applications where the load remains relatively constant. Other ratios available on request. Performance Data Vent (4) Pilot () Valve () Cyl () Description Overcenter valves give static and dynamic control of loads by supplying a counterbalance pressure to the actuator. They prevent runaway in the event of hose burst and hold the load with minimal leakage. The pressure balanced valve is unaffected by back pressure, allowing service line reliefs to operate and for the valve to be used in regenerative or proportional valve systems. The overcenter valve should be mounted either into, onto or as close to the actuator as possible to give imum protection. Single overcenter valves control unidirectional loads such as in aerial platforms, cranes or winches and dual overcenters are suited to bi-directional motion such as wheel motor applications or cylinders going over center.

The pilot assisted relief valve section will give controlled movement when pilot pressure is applied. The relief section is normally set to open at a pressure at least. times the imum load induced pressure but the pressure required to open the valve and allow movement depends on the pilot ratio of the valve. or optimization of load control and energy usage, a choice of pilot ratios is available. The pressure required to open the valve and start actuator movement can be calculated as ollows: Pilot Pressure = (Relief Setting) - (Load Pressure) A system of check valves allows crossline relief for dynamic applications with the optional make up facility to compensate for any change in system volume. eatures This valve provides complete circuit control and protection as with the standard motion control valve but has the addition of a brake release shuttle and brake port contained in a single body. : (standard) Best suited for applications where load varies and machine structure can induce instability. 8: Best suited for applications where the load remains relatively constant. Performance Data Description Motion control and lock valves give static and dynamic control by regulating the flow into and out of hydraulic actuators. When installed close to an actuator, the valve can stop runaway in the event of hose burst. The valves also give dual thermal and overload relief protection. A low pressure tank or charge line may be connected to the T port to provide a make-up flow to either actuator port. The shuttle valve provides a signal from the high pressure side of the actuator to release sprung applied brakes.

117 CEBL - BoomLoc Valves Hose Burst Protection (RE: ISO864) The valves function is to prevent uncontrolled lowering of the boom in the event of hose rupture. These valves comply with International Standard ISO864 for hydraulic excavators and backhoe loaders incorporating servo pilot systems. The valves' function is to prevent uncontrolled towering of the boom in the event of hose rupture. Closure of the valve is activated by bringing the main control valve lever to the neutral position. By separating the relief and pilot function into two individual cartridges, the pilot cartridge has no relieving function, hence any load on the valve does not affect its opening characteristics. Consequently, the valve will always open at the same pilot pressure/joystick position, regardless of load. This feature enables the valve to be tuned to open in harmony with the machine's own main control valve, giving better control. The pilot cartridge is generally set to dwell to bar behind the main control valve, therefore the Integrated Hydraulics valve takes control in the event of hose failure. When fitted to the arm/dipper cylinder, this dwell behind the main control valve prevents acceleration when 'arm down' is selected. ig. and show typical circuits utilizing these components. Line mountings or SAE flange mountings are available for direct fitment to the actuator. Where line mounted models are used it is essential that steel pipes are used between the valve and the actuator.

Both the pilot P Load Servo pilot inlet and the relief sections are unaffected by back pressure, enabling the service line reliefs to operate normally, without interfering with the spool valve control as it meters the return flow. In the event of hose failure, the control will be passed from the main spool to the overcenter valve, maintaining control of the cylinder. The pressure required to open the valve and start actuator movement can be calculated as follows: Pilot Pressure = (Relief Setting) - (Load Pressure) eatures This is a compact design with good dirt tolerance.
