The Sun Hydraulics RSHS8WN (RSHS8WN) is a normally closed poppet element valve featuring an integral pilot control cavity, designed for precise pressure regulation. This valve is externally drained and utilizes a balanced poppet design, making it suitable for applications requiring consistent pressure control. It accepts any T8A pressure control cartridge in its pilot control cavity, allowing for customizable pressure settings. When the inlet port 1 reaches the set pressure of the pilot cartridge, the poppet element begins to open towards port 2, throttling flow to maintain the desired pressure differential between port 1 and the drain port 3. The valve is insensitive to back pressure at port 2 up to its set point, and can replace two-port relief valves when return line pressure is present. The RSHS8WN's main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and reliability in operation. Pressure at port 3 directly adds to the valve setting at a 1:1 ratio but should not exceed 5000 psi (350 bar). The valve's design includes a floating style construction to prevent internal parts from binding due to excessive installation torque or machining variations of cavity/cartridge interfaces. This model supports up to 60 gpm (240 L/min) capacity and operates effectively under maximum pressures of up to 5000 psi (350 bar). It features a fast typical response time of just 2 milliseconds and maintains minimal leakage at reseat with only about ten drops per minute. The RSHS8WN also accommodates maximum pressures at port 2, making it ideal for cross-port relief circuits. The pilot control cartridges are sold separately and offer solenoid, air pilot, or hydraulic pilot operations for versatile application needs.

This valve is a normally closed poppet element that incorporates an integral pilot control cavity. It is externally drained, and is a balanced poppet design. The pilot control cavity will accept any T-8A pressure control cartridge. When the pressure at the inlet (port 1) reaches the pilot control cartridge's setting, the poppet element starts to open to port 2, throttling flow to regulate the pressure. The pilot cartridge's setting determines the difference in pressure between the inlet (port 1) and the drain (port 3). These valves are insensitive to back pressure at port 2, 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).
- NOTE: With the -8 control option, the main stage valve should first be installed to the correct torque value. The T-8A pilot control valve should then be installed into the main stage valve to its required torque value.
- The -8 control option allows the pilot control valve to be incorporated directly into the end of the relief cartridge via the T-8A cavity. These pilot control cartridges are sold separately and include solenoid operation, air pilot operation, and hydraulic pilot operation. See Pilot Control Cartridges.
- Because the modulating occurs inside the cartridge these valves are immune to most of the problems associated with cavitation, namely noise and manifold erosion.
- Will accept maximum pressure at port 2; suitable for use in cross port relief circuits.
- 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.
