The Sun Hydraulics RSHCCAV (RSHCCAV) is a pilot-operated, balanced piston sequence valve designed to supply a secondary circuit with flow once the inlet port pressure exceeds the valve setting. This valve precisely manages pressure at port 1 relative to the drain port 3, remaining unaffected by back pressure at port 2 up to its set point. It is interchangeable with all 3-port sequence cartridges of the same frame size, offering flexibility in installation and operation. The valve features a stainless steel screen protecting the main stage orifice and allows for pilot flow increase as inlet pressure rises above the set point. With a maximum operating pressure of 5000 psi (350 bar), it is not suitable for load-holding applications due to spool leakage. The RSHCCAV employs Sun's floating style construction to prevent internal binding from excessive torque or machining variations. It supports adjustable settings via W and Y controls, with or without special settings, across its full range. Specifications include a cavity T-17A, series 3 capacity of 60 gpm (240 L/min), typical response time of 10 ms, and maximum valve leakage of 4 in\u00b3/min at 1000 psi (65 cc/min at 70 bar). The valve's hex size is 1\u00bc in. (31.8 mm), with installation torque between 150-160 lbf-ft (203-217 Nm). Adjustment involves an internal hex screw size of ^5/32 in. (4 mm) and locknut hex size of ^9/16 in. (15 mm) with torque between 80-90 lbf-in (9-10 Nm). Weighing approximately 1.50 lb (0.70 kg), it comes equipped with a Viton seal kit (990017006).
