6 nformation Guide wo-pipe vs Four-Pipe he two- or four-pipe designation refers to the radiant distribution system of the radiant heating and/or cooling product. A two-pipe system includes only one supply and only one return pipe to each unit, which serves as the heating and/or cooling coil. he four-pipe system includes two supply and two returns per unit comprising of a hot water loop and chilled water loop. wo-pipe systems are less flexible than a four-pipe system. he entire building will either be in heating or cooling mode during the seasons. A changeover system, meaning it can be changed from heating to cooling or vice versa, is typically done twice a year as the season changes. his can cause some users discomfort when unusual weather patterns occur. he benefit to the two pipe system is the reduction in capital cost to the building. here is less piping length, coils, pumps, connections, etc. in the system making the upfront cost very attractive. Four-pipe systems have the ability to supply heat to one room while cooling another. his provides increased user comfort in the space as the weather outside changes. here is a larger capital cost to the system as two sets of pipe lengths, coils, pumps, connections, etc. will increase the upfront cost of the building. A four pipe system can provide more flexibility with control options and accuracy in the operation of the system. 2-Way System Overview Valve control is used to provide the variable load flow. dentical thermal response relating to the load is achieved with either a 2-Way or 3-Way valve and actuator. he three-way valve is usually in the mixing location, installed on the return side of the coil. Mixing valve implies that two inlets, one from the coil return and one from the bypass, come together and exit out of one point. he 2-Way valve has one inlet and one outlet which essentially throttles the flow. he two-way valve has the added feature of variable flow through the system and coil. his allows reduction in pump pressure and size and reductions in system energy as zones are turned on or off. Because of the dynamics of the pressure variations, application of two-way valves requires careful design attention to the location of the constant pressure point, maximum allowable pressure differential across the valves, and characteristic curves of the pumps. wo-pipe vs Four-Pipe 2-Pipe System 4-Pipe System Maximum Flow and Close off Pressure (PS) for RadKits Valve Basic ntermediate/deluxe SA Size GPM PS GPM PS Max. GPM 1 /2" /4" " oise Sensitive Applications (SA) All valves and pipes make noise as we introduce fittings, elbows, flow control and even balancing devices. All these components add pressure drop when introduced to the flow of the system. oise is caused either by the excess flow through pipes and components that are too small or by high pressures in the system that forces the flow through components that have improperly sized Cv s. he solution is selecting the right piping package while limiting the flow as indicated in the table below and not over pressurizing the system. Over pressurizing the system does not increase the heat transfer or efficiency of the system. he table below indicates the maximum flow recommended for a noise sensitive application given the valve size and the Cv.

7 nformation Guide Automatic (Fixed Flow) vs Manual Balance Valves A balancing valve is an inexpensive piece of equipment that has disproportionately high impact on how a building heating or cooling system can and will operate. Without balancing, proper control would be difficult and may even be impossible. sing a balancing valve reduces overflow to the coil, reduces potential valve chatter, wear, and failure, and reduces pumping requirements. t also provides control so the equipment can perform the function they are designed to provide. Manual Balancing Valve his is still one of the most commonly specified methods of balancing. hese valves are supplied with a specific Cv based on the original design selection (o learn more about Cv, please reference he Engineering Handbook on page???). he Cv indicates the valves characterized flow across a pressure differential of 1 PS. (Ex. A Cv of 2.0 indicates that at 1 PS the valve will have a flow of 2.0 GPM.) he balancer can test the pressure across the valve and adjust the flow using the throttling valve to the specified flow based on the Cv chart of flow verse pressure differential. he pressure differential range of the manual balancing valve is typically between 0.5 and 5 PS. Conventional manual balancing valves require more than one pass of the system before a balance can be achieved. Adjusting one valve in the system circuit changes the pressure and flow through every other valve in that circuit. t typically takes 3 passes or more to ensure that adequate balance has been achieved to the entire system. his is known as est, Adjust, and Balance and is part of the commissioning process of all buildings and systems. Automatic (Fixed Flow) Balancing Valve Automatic valves, also known as fixed flow valves, functions by controlling a set flow (usually design flow) across a large range of differential pressure. (e PSD) his adds great benefits to dynamic systems when the pressure changes due to the activation or deactivation of a zone. he automatic valve will function at the fixed flow setting as long as the minimum differential pressure is maintained. he design of the system and pumps, when using an automatic valve, should control the overall pressure in the system to ensure all Automatic balancing valves receive the appropriate pressure. he value of the Automatic balancing valve eliminates a large portion of the cost during the test, adjust and balance of the system. Balancers need only check and ensure that the automatic valve differential pressure is between 2-80 PS to know that the flow has been achieved for the particular coil unit. his can usually be accomplished during the first pass of the system.

Without balancing, proper control would be difficult and may even be impossible. sing a balancing valve reduces overflow to the coil; potential valve chatter, wear, and failure; and pumping requirements. t also provides control so the equipment can perform the function it is designed to provide. Manual Balancing Valve his is still one of the most commonly specified methods of balancing. hese valves are supplied with a specific Cv based on the original design selection. he Cv indicates the valve's characterized flow across a pressure differential of 1 psi. (Ex. A Cv of 2.0 indicates that at 1 psi, the valve will have a flow of 2.0 gpm.) he balancer can test the pressure across the valve and adjust the flow using the throttling valve to the specified flow based on the Cv chart of flow vs. pressure differential. he pressure differential range of the manual balancing valve is typically between 0.5 and 5 psi. Conventional manual balancing valves require more than one pass of the system before a balance can be achieved. Adjusting one valve in the system circuit changes the pressure and flow through every other valve in that circuit. t typically takes three passes or more to ensure that adequate balance to the entire system has been achieved. his is known as "test, adjust, and balance," and is part of the commissioning process of all buildings and systems. he manual flow control valve is pressure dependant ball-type flow control device calibrated to the selected flow rate. t incorporates a memory stop and two P/ (Pressure/ emperature) ports to accurately adjust and balance the coil flow in the field. ominal Size: ½ Automatic (Fixed Flow) Balancing Valve Automatic valves, also known as fixed flow valves, function by controlling a set flow (usually design flow) across a large range of differential pressure (ie psid). his adds great benefits to dynamic systems when the pressure changes due to the activation or deactivation of a zone. he automatic valve will function at the fixed flow setting as long as the minimum differential pressure is maintained. he design of the system and pumps, when using an automatic valve, should control the overall pressure in the system to ensure all automatic balancing valves receive the appropriate pressure. he value of the automatic balancing valve eliminates a large portion of the cost during the test, adjust and balance of the system. Balancers need only check and ensure that the automatic valve differential pressure is between 2-80 psi to know that the flow has been achieved for the particular coil unit. his can usually be accomplished during the first pass of the system. he automatic flow control valve is a pressure compensated automatic fixed flow control device designed to limit the flow rate through the coil. Desired flow rate (GPM) must be specified when ordering. he Y-body allows the cartridge to be changed in the field without dismantling the piping and incorporates the isolation ball valve and a union. he union allows easy left hand and right hand changeover. ncluded in the assembly are P/ ports for temperature and pressure management. ominal Size: ½ Shut-off Valves - Manual Ball Valve with P and Memory Stop he manual ball valve has an adjustable stop position lever to limit the travel of the on/ off handle. his allows the ball valve to be closed and returned to the balance setting without re-testing the system. ominal Size: ½ ACVE AD PASSVE BEAMS mperial dimensions are converted to metric and rounded to the nearest millimetre.
