PREPARATION and OPERATIONPrior to connecting gas/liquid flow lines inspect all parts of thepiping system including ferrules and fittings for dust or othercontaminants. Be sure to observe the direction of flow as indi-cated by the arrow on the front of the valve when connectingthe fluid flow system to be monitored.Insert tubing into the compression fittings until the ends of theproperly sized tubing home flush against the shoulders of thefittings. Compression fittings are to be tightened according tothe manufacturer's instructions to one and one quarter turns.Avoid over tightening.Once installed inline with the gas or liquid to be controlled,apply a variable DC power source at the two solenoid wires toproportionally open and close the solenoid valve (there is nopolarity). The valve is set to begin opening at approximately 5VDC. They can also serve as "on off" valves (valves are notguaranteed for absolute closure). Optional PSV-D DRIVERMODULE is available when use of a 0 to 5 VDC or 4 to 20 mAreference control signal is desired. Contact your distributor orAalborg7 for more information.SPECIFICATIONSPOWER INPUT: 0 to 30 VDC.MAXIMUM CURRENT REQUIRED: 400 mA.ELECTRICAL CONNECTION: Male spade connectors.TYPE OF OPERATION: Normally closed (nc).CONNECTIONS: 1/4 inch compression fittings,optional 1/8 inch for sizes 1, 2, 3and 3/8 inch.DIMENSIONS: 3.55 inch (90.2mm) high x 3.25inch (82.6mm) long (with fittings)x 1.00 inch (25.4mm) deep.WETTED MATERIALS: Types: 316 and 416 stainless steel,VITON7 O-rings; BUNA-N7, EPR orKALREZ7 O-rings are optional.MAXIMUM PRESSURE: 1000 psig (6896 kPa).MAXIMUM DIFFERENTIALPRESSURE:50 psid (345 kPa).MAXIMUM INTERNAL LEAK: 0.5% FS.LEAK INTEGRITY: 1 X 10-9 scc / sec Helium.FLUID TEMPERATURE: 14 FF to 122 FF (-10 FC to 50 FC).MAXIMUM TEMPERATURE(TYPICAL):174 FF (79 FC) inside, 130 FF(54 FC) outside surface at 24 VDC.ENVIRONMENTAL (PER IEC 664): Installation level II; pollutiondegree II.MODELNUMBERORIFICE SIZE Cv*maximum flow[ml / min][inch] [mm] Air WaterPSV-1 0.020 0.51 0.009 3500 125PSV-2 0.040 1.02 0.033 13000 400PSV-3 0.055 1.40 0.055 21500 700PSV-4 0.063 1.60 0.068 25000 850PSV-5 0.125 3.18 0.240 100000 2873PROPORTIONATING SOLENOID VALVESpressure dropPSV Proportionating Solenoid Valves are uniquely designedto respond to variable power inputs (0-30 VDC) to regulateflow of liquids and/or gases proportionately. For added safetyPSV valves are normally closed (NC) when de-energized.* based on 10 psig [690 mbar] differential pressure. |
