The Sun Hydraulics RVEACNN (RVEACNN) is a ventable, pilot-operated, balanced piston relief cartridge valve designed for precision pressure regulation. This normally closed valve opens at the inlet port 1 when the pressure reaches its set point, allowing flow to the tank port 2 and regulating pressure through throttling. Featuring a vent port 3, it enables remote control via other pilot or 2-way valves. Known for its accuracy and smooth operation, this valve is moderately fast with low pressure rise versus flow. It is suitable for use in cross-port relief circuits but not recommended for load-holding applications due to spool leakage. The main stage orifice is protected by a 150-micron stainless steel screen, ensuring durability and reliability. The RVEACNN can handle maximum pressures at port 2 and allows backpressure on tank port 2 to be directly additive to the valve setting at a ratio of 1:1. Cartridges with EPDM seals are compatible with systems using phosphate ester fluids but are vulnerable to damage from petroleum-based substances. The Sun floating style construction minimizes binding risks during installation or due to machining variations. This cartridge fits into a T-2A cavity series and has a capacity of 30 gpm (120 L/min). It operates at maximum pressures up to 5000 psi (350 bar) with a typical response time of 10 ms. The valve's adjustment involves up to five clockwise turns, with specific torque requirements for installation and locknut adjustments. Weighing approximately .70 lb (0.30 kg), this model comes with Viton seal kits available under part number 990202006 for maintenance needs.
