The Sun Hydraulics RVEDCYV (RVEDCYV) is a ventable, pilot-operated, balanced piston relief cartridge with an external drain, designed as a normally closed pressure regulating valve. It effectively manages pressure by opening to tank port 2 when the inlet port 1 reaches the preset valve setting, thereby throttling flow to maintain desired pressure levels. This model features a vent port 3 for remote control integration and a drain port 4 to ensure insensitivity to back pressure. Known for its accuracy and smooth operation, this valve is suitable for cross-port relief circuits but not recommended for load-holding applications due to spool leakage considerations. The main stage orifice is safeguarded by a 150-micron stainless steel screen, and it accommodates maximum pressure at port 2 up to 5000 psi (350 bar). Cartridges with EPDM seals are compatible with phosphate ester fluids but can be damaged by petroleum-based substances. The valve incorporates Sun's floating style construction, minimizing internal part binding risks. With a capacity of 30 gpm (120 L/min), the RVEDCYV operates efficiently under factory settings established at 4 gpm (15 L/min) and provides a control pilot flow of 10-15 in\u00b3/min (0.16-0.25 L/min). Its response time is typically around 10 ms, and it exhibits minimal leakage under specified conditions. Installation requires specific torque settings for optimal performance, and adjustments can be made using an internal hex screw or locknut as needed.

Ventable, pilot-operated, balanced piston relief cartridges with external drain are normally closed pressure regulating valves. When the pressure at the inlet (port 1) reaches the valve setting, the valve starts to open to tank (port 2), throttling flow to regulate the pressure. They provide a vent port (port 3) that connects between the main piston and pilot stage to provide for remote control by other pilot or 2-way valves and a drain (port 4) that makes them insensitive to back pressure. These valves are accurate, have low pressure rise vs. flow, they are smooth and quiet, and are moderately fast.

  • Will accept maximum pressure at port 2; suitable for use in cross port relief circuits. If used in cross port relief circuits, consider spool leakage.
  • Main stage orifice is protected by a 150 micron stainless steel screen.
  • Not suitable for use in load holding applications due to spool leakage.
  • Pressure at port 4 is directly additive to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar).
  • Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
  • W and Y controls (where applicable) can be specified with or without a special setting. When no special setting is specified, the valve is adjustable throughout its full range using the W or Y control. When a special setting is specified, this setting represents the maximum setting of the valve.
  • Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
