The Sun Hydraulics RPGETQV (RPGETQV) is a fast-acting, pilot-operated, balanced piston relief cartridge designed to protect hydraulic components from pressure transients. These normally closed, pressure-limiting valves open quickly when the inlet port pressure reaches the valve setting, diverting flow to the tank port to prevent excessive pressure rise. Despite their rapid response time of approximately 2 ms, this speed comes at the expense of smoothness in operation. The RPGETQV features low pressure rise relative to flow and is suitable for cross-port relief circuits with caution regarding spool leakage. It can handle a maximum operating pressure of 5000 psi (350 bar) and a capacity of 50 gpm (200 L/min). The valve's main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and reliability. The RPGETQV model incorporates Sun's floating style construction to minimize internal binding risks due to installation torque or machining variations. It is not recommended for load-holding applications because of potential spool leakage. The backpressure on the tank port directly adds to the valve setting at a 1:1 ratio, which should be considered during installation and operation. This model also offers compatibility with EPDM seals for systems using phosphate ester fluids but warns against exposure to petroleum-based substances that could damage these seals. Installation specifics include a valve hex size of 1 1/8 inches (28.6 mm), requiring an installation torque between 45-50 lbf ft (61-68 Nm). The adjustment screw has an internal hex size of 5/32 inches (4 mm), while the locknut requires a torque of 80-90 lbf in (9-10 Nm). The Sun Hydraulics RPGETQV weighs approximately .50 lb (.25 kg) and provides reliable performance for applications needing quick response relief valves in hydraulic systems.

Fast-acting, pilot-operated, balanced piston relief cartridges are normally closed, pressure-limiting valves used to protect hydraulics components from pressure transients. Fast opening and closing is gained at the expense of smoothness. When the pressure at the inlet (port 1) reaches the valve setting, the valve starts to open to tank (port 2), throttling flow to limit the pressure rise. These valves have low pressure rise vs. flow and are very fast.
- 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. 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.
- Back pressure on the tank port (port 2) is directly additive to the valve setting at a 1:1 ratio.
- 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.
