2861 2/2-Way Solenoid Control Valve Made for custom engineered applications DN 0.8... 2.0 mm 1/8, sub-base or custom engineered armature Type 2861 is an extremely compact solenoid control valve and is available with an orifice up to 2mm.

19 2861 2/2-Way Solenoid Control Valve Made for custom engineered applications DN mm 1/8, sub-base or custom engineered armature Type 2861 is an extremely compact solenoid control valve and is available with an orifice up to 2mm. It is based on the standard version of Type 2871 (see datasheet). It is used as an actuator in closed control loops (pressure, flow, temperature, etc.). Compared with the standard version, the valve is essentially of simpler construction and assembly and testing procedures are optimized, easing high volume series production with shorter delivery times. Please follow the instructions for a customised design on page 5 of this datasheet. Circuit function A A direct acting 2-way solenoid control valve, normally closed P Valve control takes place through a PWM signal 1). The duty cycle of the PWM signal determines the coil current and hence the position of the plunger. The Bürkert control electronics Type 8605 (see relevant datasheet) converts an analog signal to a reference value corresponding to the valve type PWM signal and provides additional functions such as temperature compensation (coil heating), ramp function and the adjustment of min. and max. duty cycle/coil current for the control range.

2865 2/2-Way Solenoid Control Valve Made for custom engineered applications DN 2.

29 2865 2/2-Way Solenoid Control Valve Made for custom engineered applications DN mm Port connection 3/8", 1/2 or customer specific Type 2865 is an extremely compact solenoid control valve and is available with an orifice up to 8mm. It is based on the standard version of Type 2875 (see datasheet). It is used as an actuator in closed control loops (pressure, flow, temperature, etc.). Compared with the standard version, the valve is essentially of simpler construction and assembly and testing procedures are optimized, easing high volume series production with shorter delivery times. Please follow the instructions for a customised design on page 5 of this datasheet. Circuit function A A P direct acting 2-way solenoid control valve, normally closed Valve control takes place through a PWM signal 1). The duty cycle of the PWM signal determines the coil current and hence the position of the plunger. The Bürkert control electronics Type 8605 (see relevant datasheet) converts an analog signal to a reference value corresponding to the valve type PWM signal and provides additional functions such as temperature compensation (coil heating), ramp function and the adjustment of min. and max. duty cycle/coil current for the control range.

The optimum size should be selected such that the resulting flow in the system is not unnecessarily reduced by the valve. However, a sufficient part of the pressure drop should be taken across the valve even when it is fully opened. Recommended value: Δp valve > 25 % of total pressure drop within the system Otherwise, the Ideal, linear valve curve characteristic is changed.

Through the movement between the 2 end positions, the switching element (flipper) seals one of the two opposing valve seats and connects the other to the working port.

39 6144 3/2-way Flipper Solenoid Valve Type 6144 can be combined with... Direct-acting 0 to 10 bar Low power consumption Sub-base connection 10mm width per station Standard, EEx ia Version Type 6524 Servo-assisted pneumatic valve Type 6144 Multiple manifolds (e.g. 6 valves) Type 6144 is a direct-action 3/2-way solenoid valve designed for neutral gases and liquids. Through the movement between the 2 end positions, the switching element (flipper) seals one of the two opposing valve seats and connects the other to the working port. This movement is caused by the solenoids magnetic field pushing a permanent magnet that is fixed to the flipper element. In addition to its exceptional performance characteristics, the flipper principle is especially marked by its very low switching noise and its low wear level. Furthermore, integrated medium separation enables use above and beyond pneumatic applications. Depending on the case of operation, various flange connections are available that are suitable for both individual and block mounting. Installation advice: The valve must have a minimum distance of 5 mm from other ferromagnetic materials in order to avoid malfunctioning during operating conditions.

44 6624 TwinPower 2/2 and 3/2-way Rocker Solenoid Valve for analytical applications 10 mm width Orifice DN 0.8 to DN 1.6 with pressure range vacuum to 5 bar Medium separation, for aggressive fluids Direct acting Type 6624 combines the reliable and successful Rocker principle with a highly innovative new actuator. The TwinPower concept of this actuator reduces the size greatly without loss in performance. Hence the 10 mm wide medium isolated rocker valve, 6624, with a 1.6 mm orifice and a pressure resistance of 2 bar, provides the same performance as a traditional 16 mm valve. In addition, the integrated power reduction decreases the energy consumption by 75%. In combination with other design features the heat transfer into the medium can be reduced to a minimum. In the design of the 6624, the main benefits lie in its excellent cleanability and a high reliability. By using high performance materials the 6624 suits the handling of aggressive medium perfectly. The valve is available in a 2-way and 3-way version.

69 2871 2/2-Way Solenoid Control Valve Excellent range (1:200) Very good response Compact valve design Orifice sizes mm Port connection 1/8 or sub-base Type 2871 can be combined with Type 8605 Digital control electronics DIN-rail version Type 2507 Cable plug Type 8611 Universal controller The direct-acting solenoid control valve Type 2871 (20mm installation width) is used as the regulating unit in control loops. Due to an elastomeric seat seal the valve closes tight (integrated shut-off function),up to the DN specific nominal pressure, see ordering chart on page 3. The plunger of the valve is assembled frictionless, which leads to an extraordinary adjustment characteristic. This valve is particularly suitable for demanding control tasks (high control range, dry gases, etc.). Circuit function A A P direct acting 2-way solenoid control valve, normally closed Valve control takes place through a PWM signal 1). The duty cycle of the PWM signal determines the coil current and hence the position of the plunger. Optionally the valve can also be driven with DC voltage. Please note the sizing comments for such a control valve on page 2. 1) PWM pulse width modulation 2) Pressure data [bar]: Measured as overpressure to the atmospheric pressure, nominal pressure further depends on orifi ce size 3) Maximum value, value depends on operating pressure 4) Characteristic data of control behaviour depends on process conditions 5) By fl ow measurement Technical Data - Valve Body material Seal material Medium Pressure range Brass, stainless steel FKM, EPDM on request Neutral gases, liquids on request bar 2) also applicable for technical vacuum Medium temperature C Ambient temperature max. +55 C Power supply 24 V DC PWM frequency 1500 Hz Max. coil current 220mA 3) Power consumption 2 W (up to DN 0,6), 5 W (from DN 0,8) Duty cycle 100% continuously rated Port connection Sub-base, G 1/8, NPT 1/8, others on request Electrical connection Cable plug Type 2507, Form B industrial standard Installation As required, preferably with actuator in upright position Typical control data 4) at PWM control Hysteresis Repeatability Sensitivity Span Response time (10-90%) Protection class valve < 5% < 0.25% FS 5) < 0.25% FS <0.1% FS with DN <0.8 mm 5) 1:200 (DN0.8-2), 1:500 (DN ) < 15 ms IP65 Technical data - Control electronics Type 8605 (see separate datasheet) The valve control can take place through the control electronics of Type 8605, which converts an analogue input signal into a PWM signal.

The optimum size should be selected such that the resulting flow in the system is not unnecessarily reduced by the valve. However, a sufficient part of the pressure drop should be taken across the valve even when it is fully opened. Recommended value: Δp valve > 25 % of total pressure drop within the system Otherwise, the ideal, linear valve curve characteristic is changed.

94 6124 2/2 and 3/2-way Flipper Solenoid Valve, with hermetic isolation of fluid Low internal volume Low power consumption High back pressure tightness Optional impulse model Type 6124 can be combined with... DN 0.6 mm Manifolds Thanks to the patented Bürkert flipper technology, the direct-acting Type 6124 solenoid valve is unique. It combines fast, precise switching behaviour with reliable media separation, and the design eliminates heat transfer between fluid and coil. FKM and PEEK allows the use of neutral and slightly aggressive fluids. The optional impulse model works with the smallest energy requirement, and is therefore especially suitable for battery operation; the heat transfer to the medium is negligible for this model. A minimal dead volume and gap-free internal design make it possible to use it in medical, analytical and laboratory technology.

Modular Water Valve System servo-assisted; variable and extendable Type 6227 2/2 way; DN 10-13 mm; 1 up to 7 bar Advantages / Benefits Reduction of Cost of Ownership up to 60% Modular system design

118 Modular Water Valve System servo-assisted; variable and extendable Type /2 way; DN mm; 1 up to 7 bar Advantages / Benefits Reduction of Cost of Ownership up to 60% Modular system design Block assembly by lock technology Easy change between distributing and collecting function by turn of valve insert Free combination of valve sizes DN10 and DN13 High flexibility with different port connections also with integrated check valve Flexibility with additional functions (integrable sensors, separation of fluids, additional inputs) Low weight by thermoplastic technology Waterhammer free Design/Function Applications The servo-assisted solenoid valve with servo diaphragm is normally closed (NC). In this condition, a pressure is being built up above the diaphragm - the valve holds tight. When energized, the space above the servo diaphragm is pressure relieved and lifted up by the medium - the valve opens. The modular extendable valve system can be built up in all possible combinations with up to 12 valves each as distributor or collector in two sizes with different port connection modules. The valve can be put together in collecting function or distributing function by easily twisting the valve insert. Any kind of combination of functions in one block is possible. Additional functions as e.g. temperature indication or flow measurement can be added by integrating a corresponding sensor directly into the valve block. In order to be as flexible as possible, a variety of port connections is available as standard. The inner thread port connections are at the bottom, pointing downwards while the outer thread port connections and the plug-on connection for hoses are pointing sidewards. The block material is Polyamide glass-fiber reinforced. The advantages are: Low weight and a certain chemical resistance.

Type 2506 Cable plug to DIN EN Form C 2) Type 2507 Cable plug industrial standard Form B Type 2510 ASI cable plug The Type 6228 is a servo-assisted 2/2-way solenoid valve with servo-diaphragm. It is particularly suited for neutral media. Without electrical power, this solenoid valve is closed. Pressure builds up through the servodiaphragm, which pushes the latter downwards and thereby keeps the valve closed. On switching, the space above the servo-diaphragm will be relieved via the pilot valve. As a result, the pressure of the medium lifts the servo-diaphragm, and the main valve opens. A minimum differential pressure of 0.5 bar is required for complete opening and closing. The special design and geometry of the internal parts of the valve produce a soft closing function with very low pressure peaks only. It is very simple to extend the valve radially.
