The Sun Hydraulics RVCANCV (RVCANCV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation in hydraulic systems. This normally closed valve begins to open once the inlet port pressure reaches the preset valve setting, allowing flow to the tank port and managing system pressure effectively. It features a vent port that facilitates remote control by other pilot or 2-way valves, offering enhanced versatility in system design. The RVCANCV is noted for its accuracy, smooth operation, and moderate response speed. This cartridge is suitable for cross-port relief circuits due to its ability to accept maximum pressure at port 2; however, users should consider spool leakage in such applications. It includes a 150-micron stainless steel screen protecting the main stage orifice. Notably, it is not recommended for load-holding applications because of potential spool leakage. Back pressure on the tank port directly adds to the valve setting at a 1:1 ratio. The RVCANCV incorporates Sun's floating style construction to reduce internal binding risks from installation torque variations or machining inconsistencies. It can handle systems with phosphate ester fluids when equipped with EPDM seals but should avoid petroleum-based fluids due to seal incompatibility. With a capacity of 15 gpm (60 L/min) and maximum operating pressure of 5000 psi (350 bar), this valve provides reliable performance under demanding conditions. The control pilot flow ranges between 7-10 in\u00b3/min (0.11-0.16 L/min), with a typical response time of 10 ms. Maximum leakage at specified conditions is limited to 2 in\u00b3/min (30 cc/min). Installation requires specific torque settings: valve hex size is 7/8 inch with an installation torque of 30-35 lbf ft; adjustment screw internal hex size is 5/32 inch; locknut hex size is 9/16 inch with locknut torque set between 80-90 lbf in.
