The Sun Hydraulics RPGC8DV (RPGC8DV) is a sophisticated hydraulic valve designed as a normally closed modulating element with an integral pilot control cavity. This balanced piston valve is engineered to accept any T8A pressure control cartridge, allowing it to start opening to tank port 2 and throttle flow when the inlet port 1 pressure reaches the pilot control cartridge's setting. The resulting pressure difference between port 1 and port 2 is determined by the pilot cartridge's setting. Notably, this valve can withstand maximum pressure at port 2, making it suitable for cross-port relief circuits; however, it should not be used in load-holding applications due to potential spool leakage. Additionally, back pressure on the tank port is directly additive to the valve setting at a 1:1 ratio. The RPGC8DV features a main stage orifice protected by a 150-micron stainless steel screen and incorporates Sun's floating style construction to minimize internal part binding due to excessive torque or machining variations. It requires careful installation of both the main stage valve and T8A pilot control valve, which are sold separately and include various operation options such as electroproportional, solenoid, air pilot, and hydraulic pilot operation. The valve has a capacity of up to 50 gpm (200 L/min) with a maximum operating pressure of 5000 psi (350 bar). It also supports systems using phosphate ester fluids when configured with EPDM seals but should avoid exposure to petroleum-based substances. With its robust design and versatile application potential, this cartridge is ideal for regulating pressures in hydraulic circuits while maintaining operational integrity under demanding conditions.

This valve is a normally closed modulating element that incorporates an integral pilot control cavity. It is a balanced piston design. The pilot control cavity will accept any T-8A pressure control cartridge. When the pressure at the inlet (port 1) reaches the pilot control cartridge's setting, the modulating element starts to open to tank (port 2), throttling flow to regulate the pressure. The pilot cartridge's setting determines the difference in pressure between port 1 and port 2.
- All 2-port relief cartridges (except pilot reliefs) are physically and functionally interchangeable (same flow path, same cavity for a given frame size).
- Will accept maximum pressure at port 2; suitable for use in cross port relief circuits.
- Main stage orifice is protected by a 150 micron stainless steel screen.
- Not suitable for use in load holding applications due to spool leakage.
- Back pressure on the tank port (port 2) is directly additive to the valve setting at a 1:1 ratio.
- NOTE: With the -8 control option, the main stage valve should first be installed to the correct torque value. The T-8A pilot control valve should then be installed into the main stage valve to its required torque value.
- The -8 control option allows the pilot control valve to be incorporated directly into the end of the relief cartridge via the T-8A cavity. These pilot control cartridges are sold separately and include electro-proportional, solenoid, air pilot, and hydraulic pilot operation. See Pilot Control Cartridges.
- 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.
