The Sun Hydraulics RSHCQBV (RSHCQBV) is a pilot-operated, balanced piston sequence valve designed to supply a secondary circuit with flow once the inlet pressure at port 1 surpasses the valve's setting. This sequence valve controls the pressure at port 1 relative to the drain port 3 and remains unaffected by back pressure at port 2 up to the valve setting. It can substitute for 2-port relief valves when there is return line pressure and offers functional interchangeability across all three-port sequence cartridges of similar frame sizes. The valve features a main stage orifice protected by a 150-micron stainless steel screen, ensuring durability and reliability. The RSHCQBV model is not intended for load holding applications due to potential spool leakage. It incorporates Sun's floating style construction, which minimizes internal part binding from excessive installation torque or machining variations. With a capacity of 60 gpm (240 L/min) and maximum operating pressure of 5000 psi (350 bar), this valve is adjustable throughout its full range using W or Y controls unless a special setting is specified. The factory pressure settings are established at 4 gpm (15 L/min), with control pilot flow ranging between 15-20 in\u00b3/min (0.25-0.33 L/min) and typical response time around 10 ms. Additional specifications include a maximum valve leakage of 4 in\u00b3/min at 110 SUS (24 cSt) under conditions of 1000 psi (70 bar), with adjustment requiring up to five clockwise turns to increase settings. The valve hex size measures at 1\u00bc inches (31.8 mm), with installation torque recommended between 150-160 lbf\u00b7ft (203-217 Nm). The adjustment screw has an internal hex size of ^5\u204432 inches (4 mm), while the locknut hex size is ^9\u204416 inches (15 mm) with locknut torque set between 80-90 lbf\u00b7in (9-10 Nm). This model weighs approximately 1.50 lb (0.70 kg) and uses Viton seal kits such as part number: 990017006 for maintenance purposes.

Pilot-operated, balanced piston sequence valves will supply a secondary circuit with flow once the pressure at the inlet (port 1) has exceeded the valve setting. The pressure setting of a sequence valve controls the pressure at port 1 relative to the pressure at the drain (port 3). These valves are insensitive to back pressure at port 2 (sequence), up to the valve setting. They may be used to regulate pressure in place of 2-port relief valves if there is pressure in the return line.
- All 3 port sequence cartridges are physically and functionally interchangeable (i.e. same flow path, same cavity for a given frame size).
- Pilot flow continues to increase as the pressure at port 1 (inlet), relative to the pressure at port 3 (drain), rises above the valve setting.
- The main stage orifice is protected by a 150 micron stainless steel screen.
- Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar).
- Not suitable for use in load holding applications due to spool leakage.
- W and Y controls (where applicable) can be specified with or without a special setting. When no special setting is specified, the valve is adjustable throughout its full range using the W or Y control. When a special setting is specified, this setting represents the maximum setting of the valve.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
