VEP03MSV-PDRP -3-WAY PROPORTIONAL PRESSURE REDUCING/RELIEVING VALVES VEP03MSV-PDRP 3-WAY PROPORTIONAL PRESSURE REDUCING/RELIEVING VALVES DESCRIPTION The VEP03MSV-PDRP is a D03 modular three-way proportional pressure reducing/relieving valve conform to NFPA D03/ISO 4401 mounting standards. OPERATION These valves are designed to provide remote variable pressure control in the pressure port of a secondary circuit. The controlled pressure is proportional to the amount of current supplied to the solenoid. TYPICAL PERFORMANCE SPECIFICATIONS MAXIMUM OPERATING PRESSURE MAXIMUM FLOW RATE P - A - B Ports 4600 psi 320 bar T Port 30 psi 2 bar Controlled line 8 gpm 30 l/min Free line 13.2 gpm 50 l/min As flow demands change, the valve opening will modulate to maintain the circuit pressure. The VEP03MSV-PDRP will also relieve the tank to vent a load induced pressure spike. In evento of a loss in electrical power, the valve spool will return to the low pressure condition. The proportional solenoids can be driven by a variable current power supply or by use of external Power Amplifier Cards designed to maximize the valve performance.

VEP03MSV-PDRP -3-WAY PROPORTIONAL PRESSURE REDUCING/RELIEVING VALVES APPLICATION DATA FLUIDS All pressure drops shown on these data pages are based on 170 SUS fluid viscosity and 0.87 specific gravity. For any other specific gravity (G1) the pressure drop ( P) will be approx. P1 = P (G1/G). See the chart for other viscosities.

For these fluids, use NBR seals. For fluids HFDR type (phosphate esters) use FPM seals (code G). For the use of other kinds of fluid such as HFA, HFB, HFC, please consult our technical department. Using fluids at temperatures higher than 180 degrees F causes the accelerated degradation of seals as well as degradation of the fluids physical and chemical properties. From a safety standpoint, temperatures above 130 degrees F are not recommended. RANGE TEMPERATURES: FLUID VISCOSITY Ambient - 4 to +130 F -20 to +54 C Fluid - 40 to +180 F -20 to +82 C Range 60-1900 SUS 10-400 cst Recommended 120 SUS 25 cst FLUID CONTAMINATION ISO 4406:1999 Class 18/16/13 INSTALLATION We recommend the VEP03MSV-PDR valve be installed either horizontally or vertically with the solenoid downwards. The minimum regulated pressure may vary from the graphs shown on page 3 if the valve is installed vertically with the solenoid upwards. Bleed the air from the hydraulic circuit. Be sure that the solenoid tube is always full of oil. It may be necessary to vent entrapped air from the solenoid tube in certain applications or after a long shutdown period. The air bleed vent is located on the end of the solenoid tube. See page 4 for the location. Be sure to close the air bleed when the process is complete. Connect the valve T port directly to the tank. Any back pressure from the tank line will add directly to the controlled pressure. The maximum allowable back pressure in the tank line under operational conditions is 2 bar. Valves are fixed by means of screws or tie rods on a flat surface with planarity and roughness equal to or better than those indicated in the relative symbols. If minimum values are not observed, fluid can easily leak between the valve and support surface.
