The Sun Hydraulics RVIACWV (RVIACWV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation. It operates as a normally closed valve that opens when inlet pressure reaches the set threshold, directing flow to the tank port to manage pressure levels. This model features a vent port that allows for remote control via other pilot or 2-way valves. Known for its accuracy and low-pressure rise against flow, the RVIACWV provides smooth and quiet operation with moderate speed. It is suitable for use in cross-port relief circuits, accepting maximum pressure at port 2, although spool leakage should be considered in such applications. The main stage orifice is safeguarded by a stainless steel screen with a 150-micron rating. This cartridge is not intended for load-holding applications due to potential spool leakage and requires that the relief valve setting be higher than any pilot valve setting used in conjunction. The RVIACWV incorporates Sun's floating style construction to reduce risks of internal binding from excessive installation torque or machining variations. With EPDM seals, this cartridge is compatible with systems using phosphate ester fluids but should not be exposed to petroleum-based substances as they may damage the seals. The RVIACWV fits into a T-19A cavity and offers a series 4 capacity of up to 120 gpm (480 L/min). Its factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). The control pilot flow ranges from 15 to 20 in\u00b3/min (0.25 to 0.33 L/min) with typical response times around 10 ms. Maximum valve leakage is rated at 5 in\u00b3/min at 1000 psi (80 cc/min at 70 bar). Adjustments can be made through an internal hex screw, requiring specific torque values for installation and locknut adjustments.
