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 RSHCYNV (RSHCYNV) is a pilot-operated, balanced piston sequence valve designed to manage hydraulic flow in secondary circuits once the inlet pressure at port 1 surpasses the valve's set threshold. This valve effectively controls pressure at port 1 relative to the drain port 3, and is unaffected by back pressure at port 2 up to its setting. It can replace two-port relief valves in systems where there is return line pressure. Notably, all three-port sequence cartridges from Sun Hydraulics are interchangeable, offering consistent flow paths and cavity sizes for a given frame size. The main stage orifice of the RSHCYNV is protected by a durable 150-micron stainless steel screen, ensuring reliability in demanding applications. With a maximum operating pressure of 5000 psi (350 bar), this valve features an adjustable control range using W or Y controls and incorporates Sun's floating style construction to prevent internal binding due to installation or machining variations. However, it is not recommended for load-holding applications due to spool leakage. The valve has a capacity of 60 gpm (240 L/min) and offers quick response times typical at around 10 ms. The product includes specific adjustment features such as five clockwise turns to increase settings and comes with Viton seal kits for enhanced durability under various conditions.

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.
