The Sun Hydraulics RPKECNV (Material Number: RPKECNV) is a fast-acting, pilot-operated, balanced piston relief cartridge designed to protect hydraulic components from pressure transients. This normally closed, pressure-limiting valve opens quickly when the inlet port pressure reaches the valve setting, directing flow to the tank port to manage pressure rise. It features low pressure rise relative to flow and rapid response times, making it suitable for applications where speed is critical. The valve is interchangeable with other 2-port relief cartridges of the same frame size and can handle maximum pressure at port 2, making it apt for cross-port relief circuits. However, users should note potential spool leakage in such configurations. The RPKECNV includes a main stage orifice shielded by a 150-micron stainless steel screen and employs Sun's floating style construction to reduce internal binding risks due to installation torque or machining variations. It is not recommended for load-holding applications due to spool leakage concerns. The backpressure on port 2 directly affects the valve setting at a 1:1 ratio. The cartridge can handle up to 200 gpm (760 L/min) capacity and operates under a maximum pressure of 5000 psi (350 bar). Typical response time is around 2 ms, with maximum leakage at specified conditions being 5 in\u00b3/min (80 cc/min). Adjustment involves up to five clockwise turns with specified torque settings for secure installation and locknut adjustments. The product weighs approximately 2.50 lb (1.15 kg) and comes with an optional Viton seal kit for enhanced durability under varying fluid conditions.
