The Sun Hydraulics RVCDKAV (RVCDKAV) is a ventable, pilot-operated, balanced piston relief cartridge designed to provide precise pressure regulation in hydraulic systems. This normally closed valve opens to the tank port when the inlet pressure reaches the set level, effectively throttling flow to maintain desired pressure levels. It features a vent port that allows for remote control and an external drain port that ensures insensitivity to back pressure. The valve is noted for its accuracy, smooth operation, moderate speed, and low noise levels. It is particularly suited for applications requiring maximum pressure acceptance at the tank port and is useful in cross-port relief circuits, although spool leakage should be taken into account in such scenarios. The RVCDKAV model incorporates a main stage orifice protected by a 150-micron stainless steel screen and is not recommended for load-holding applications due to potential spool leakage. The valve's setting can be adjusted using W or Y controls, with options for specifying a special maximum setting. It employs Sun's floating style construction to prevent internal binding from installation torque or machining variations. This cartridge has a capacity of 15 gpm (60 L/min) and operates at pressures up to 5000 psi (350 bar). Its control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), with typical response times around 10 ms. The valve's hex size measures 7/8 inch (22.2 mm), with an installation torque between 30-35 lbf ft (41-47 Nm). The adjustment screw has an internal hex size of 5/32 inch (4 mm), while the locknut requires a torque of 80-90 lbf in (9-10 Nm). This model weighs approximately .40 lb (.20 kg) and comes with Viton seals compatible with phosphate ester fluids; however, exposure to petroleum-based substances will damage these seals.
