While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Sun Hydraulics directly.***
The Sun Hydraulics RSHCLBN (RSHCLBN) is a pilot-operated, balanced piston sequence valve designed to supply a secondary circuit with flow once the pressure at the inlet port 1 exceeds the valve setting. This valve regulates pressure at port 1 relative to the pressure at drain port 3 and is insensitive to back pressure at port 2 up to the valve setting, making it suitable for applications where pressure regulation is needed in place of two-port relief valves with return line pressure. The RSHCLBN features interchangeable three-port sequence cartridges with consistent flow paths and cavities for given frame sizes. It accommodates pilot flow increases as inlet pressure rises above the valve setting and includes a main stage orifice protected by a 150-micron stainless steel screen. The valve's maximum operating pressure is 5000 psi (350 bar), and it should not exceed this at port 3 due to its direct additive relationship with the valve setting. Notably, this model is unsuitable for load-holding applications due to spool leakage. The RSHCLBN incorporates Sun's floating style construction, minimizing internal part binding risks from excessive installation torque or machining variations. It has an adjustable range using W or Y controls, with special settings representing maximum settings if specified. Key specifications include a capacity of 60 gpm (240 L/min), typical response time of 10 ms, and maximum leakage of 4 in\u00b3/min at 1000 psi (65 cc/min at 70 bar). The adjustment screw features an internal hex size of 5/32 inch (4 mm), while locknut torque ranges from 80-90 lbf\u00b7in (9-10 Nm). This model weighs approximately 1.50 lb (0.70 kg) and utilizes a Viton seal kit for cartridge sealing needs.

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.
