The Sun Hydraulics RSDS8WN (RSDS8WN) is a high-performance, normally closed poppet valve designed with an integral pilot control cavity for precise pressure regulation. This valve features an externally drained, balanced poppet design that is compatible with any T8A pressure control cartridge. Its primary function is to regulate the pressure by opening the poppet element to port 2 when the inlet port 1 reaches the pilot control cartridge's set pressure. The valve's setting is determined by the difference in pressure between inlet port 1 and drain port 3, making it insensitive to back pressure at port 2 up to its set value. This makes it suitable for use in cross-port relief circuits and as a replacement for two-port relief valves when there is return line pressure. The RSDS8WN valve has a main stage protected by a 150-micron stainless steel screen and incorporates Sun's floating style construction to minimize internal binding due to installation torque variations. It can handle pressures up to 5000 psi (350 bar) and has a capacity of 15 gpm (60 L/min). The pilot flow increases as the inlet pressure at port 1 exceeds the valve setting relative to the drain at port 3, with a typical response time of 10 ms. The valve installation torque ranges from 30-35 lbf ft (41-47 Nm), while the pilot control valve requires a torque of 20-25 lbf ft (27-33 Nm). Equipped with Viton seals, this robust valve ensures minimal leakage with main stage leakage at reseat limited to just ten drops per minute.

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.
- 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.
