The Sun Hydraulics RVIDKEV (RVIDKEV) is a ventable, pilot-operated, balanced piston relief cartridge with an external drain, designed as a normally closed pressure regulating valve. It operates by opening to tank port 2 when the inlet port 1 pressure reaches the valve setting, thereby throttling flow to regulate pressure. The valve features a vent port 3 for remote control and a drain port 4 that renders it insensitive to back pressure. This model is recognized for its accuracy, low pressure rise versus flow, smooth operation, moderate speed, and quiet performance. It can handle maximum pressure at port 2 and is suitable for cross-port relief circuits; however, it should not be used in load holding applications due to spool leakage. The main stage orifice is safeguarded by a 150-micron stainless steel screen. Pressure at port 4 directly adds to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar). Cartridges with EPDM seals are compatible with phosphate ester fluids but are vulnerable to petroleum-based substances. Sun's floating style construction minimizes internal part binding risks due to excessive installation torque or cavity/cartridge machining variations. The RVIDKEV fits in Cavity T-24A Series 4 and has a capacity of up to 120 gpm (480 L/min). Its factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar) and control pilot flow between 15-20 in\u00b3/min (0.25-0.33 L/min). The typical response time is around 10 ms, with maximum valve leakage of approximately 5 in\u00b3/min at 1000 psi (80 cc/min at 70 bar). Adjustments require up to five clockwise turns, with specific torque requirements for installation and locknut adjustments provided for precision assembly.

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.
- 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.
