The Sun Hydraulics RVCDLCV (RVCDLCV) is a ventable, pilot-operated, balanced piston relief cartridge with an external drain, designed for precise pressure regulation in hydraulic systems. This valve is normally closed and begins to open when the inlet port 1 reaches the predetermined pressure setting, directing flow to tank port 2 to maintain the desired pressure level. It features a vent port 3 for remote control by other pilot or two-way valves and a drain port 4 that renders it insensitive to back pressure. Notable for its accuracy, low-pressure rise versus flow characteristics, smooth and quiet operation, and moderate speed, this valve is highly effective in various applications. The RVCDLCV can accept maximum pressure at port 2 and is suitable for cross-port relief circuits; however, spool leakage should be considered in such applications. The main stage orifice is safeguarded by a 150-micron stainless steel screen. It is important to note that this valve is not suitable for load-holding applications due to spool leakage. Pressure at port 4 directly adds to the valve setting at a 1:1 ratio but must not exceed 5000 psi (350 bar). Cartridges equipped with EPDM seals are intended for systems using phosphate ester fluids and are incompatible with petroleum-based fluids. This model incorporates Sun's floating style construction to prevent internal parts binding from excessive installation torque or cavity/cartridge machining variations. With a capacity of up to 15 gpm (60 L/min), it operates under a maximum pressure of 5000 psi (350 bar) and features an adjustment range facilitated by W or Y controls if specified without special settings. The RVCDLCV has a typical response time of approximately 10 ms and minimal leakage rates under specific conditions.
