The Sun Hydraulics RVCDCAV (RVCDCAV) 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 set value, thus throttling flow to maintain desired pressure levels. This valve features a vent port 3 for remote control by other pilot or two-way valves and a drain port 4 that ensures insensitivity to back pressure. Known for its accuracy and quiet operation, it has a low-pressure rise versus flow and responds moderately fast. The RVCDCAV is suitable for cross-port relief circuits but not recommended for load-holding applications due to spool leakage. This cartridge can handle maximum pressures at port 2 and incorporates Sun's floating style construction to prevent internal binding from installation torque or machining variations. It includes a stainless steel screen protecting the main stage orifice and is compatible with EPDM seals for systems using phosphate ester fluids while avoiding petroleum-based fluids that could damage the seals. The valve allows adjustments using W or Y controls across its full range unless a special setting is specified. Additional specifications include a maximum operating pressure of 5000 psi (350 bar), control pilot flow between 7-10 in\u00b3/min (0.11-0.16 L/min), and typical response time of 10 ms. The valve's installation requires specific torque settings, including a hex size of 7/8 in (22.2 mm) and installation torque between 30-35 lbf ft (41-47 Nm). The adjustment screw features an internal hex size of 5/32 in (4 mm), while the locknut has a hex size of 9/16 in (15 mm) with torque specifications ranging from 80-90 lbf in (9-10 Nm). This model weighs approximately .40 lb (.20 kg) and comes with an optional Viton seal kit identified as cartridge number: 990021006.

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.
- A remote pilot relief on port 3 (vent) will control the valve below its own setting.
- 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.
