The Sun Hydraulics RVEDKAN (RVEDKAN) is a ventable, pilot-operated, balanced piston relief cartridge with an external drain, designed for precise pressure regulation in hydraulic systems. This valve is typically closed and begins to open to tank port 2 when the inlet port 1 pressure reaches the set threshold, effectively throttling flow to manage pressure levels. It features a vent port for remote control capabilities and a drain port that ensures insensitivity to back pressure. The RVEDKAN model is known for its accuracy, smooth operation, and moderate response speed. It can handle maximum pressures at port 2 and is suitable for cross-port relief circuits, though spool leakage should be considered in such applications. The main stage orifice is protected by a durable 150-micron stainless steel screen. This model is not recommended for load-holding applications due to potential spool leakage. Pressure at port 4 directly adds to the valve setting on a 1:1 ratio but should not exceed 5000 psi (350 bar). Cartridges with EPDM seals are intended for systems using phosphate ester fluids; exposure to petroleum-based substances will damage these seals. The valve's W and Y controls allow full-range adjustments unless specified otherwise. Sun's floating style construction minimizes binding risks from excessive torque or machining variations. The RVEDKAN fits into Cavity T-22A Series 2 with a capacity of up to 30 gpm (120 L/min) and operates at pressures up to 5000 psi (350 bar). It has a typical response time of about 10 ms and minimal leakage rates under specified conditions. The valve requires specific installation torques and adjustment settings, ensuring reliable performance across various hydraulic applications.
