The Sun Hydraulics RVEDCDV (RVEDCDV) is a ventable, pilot-operated, balanced piston relief cartridge designed for accurate pressure regulation with low pressure rise versus flow. This valve is normally closed and opens to the tank port 2 when the inlet port 1 pressure reaches the set value, effectively throttling flow to maintain desired pressure levels. It features a vent port 3 for remote control and a drain port 4 that ensures insensitivity to back pressure, making it suitable for cross-port relief circuits while considering spool leakage. The main stage orifice is safeguarded by a 150-micron stainless steel screen. However, it is not recommended for load-holding applications due to potential spool leakage. The RVEDCDV can handle a maximum operating pressure of 5000 psi (350 bar) and has factory pressure settings established at 4 gpm (15 L/min). The control pilot flow ranges from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min), with a typical response time of about 10 ms. Maximum valve leakage at 110 SUS (24 cSt) is approximately 3 in\u00b3/min (50 cc/min) at 1000 psi (70 bar). The valve allows adjustments via an internal hex screw, with up to five clockwise turns increasing the setting. This model incorporates Sun's floating style construction to reduce internal binding risks due to installation torque or cavity machining variations. It features an installation torque requirement of between 45 and 50 lbf ft (61-68 Nm) with specific hex sizes for adjustment and locknut operations. The cartridge's weight is approximately .70 lb (.30 kg), and it can be configured with EPDM seals for use in systems utilizing phosphate ester fluids, though exposure to petroleum-based substances should be avoided as they may damage the seals.

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.
