The Sun Hydraulics RSHCQAV (RSHCQAV) is a pilot-operated, balanced piston sequence valve designed to supply a secondary circuit with flow once the inlet port 1 pressure exceeds the valve setting. This valve is ideal for applications where pressure regulation is required in place of 2-port relief valves, especially when there is pressure in the return line. It features a 150-micron stainless steel screen protecting the main stage orifice and is insensitive to back pressure at port 2 sequence up to the valve setting. The valve's construction allows for interchangeable use across all 3-port sequence cartridges, maintaining consistent flow paths and cavity sizes for a given frame size. The RSHCQAV model incorporates Sun's floating style construction to reduce internal binding risks due to excessive installation torque or machining variations. It has a maximum operating pressure of 5000 psi (350 bar) and a capacity of 60 gpm (240 L/min). 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. Valve leakage at maximum conditions measures approximately 4 in\u00b3/min (65 cc/min) at 1000 psi (70 bar). Adjustments can be made using W or Y controls, with or without special settings, and are adjustable throughout their full range when no special setting is specified. The valve's hex size is 1-1/4 inches (31.8 mm), with an installation torque requirement of 150-160 lbf-ft (203-217 Nm). It weighs approximately 1.50 lb (0.70 kg) and uses Viton seal kits for optimal performance under various conditions.
