The Sun Hydraulics SDHTCWN (SDHTCWN) is a pilot-operated anti-shock relief cartridge designed to limit maximum system pressure and control the rate of pressure rise. This valve is engineered to open and ramp closed at a constant speed, unaffected by settings and flow rates, with an adjust screw to determine both maximum relief and minimum threshold settings. Featuring an external drain, the valve remains insensitive to pressure at port 2, making it suitable for cross-port relief circuits. The internal modulation of the cartridge protects against cavitation issues like noise and manifold erosion. It is crucial to note that this valve is not appropriate for sequencing cylinders or load-holding applications. The SDHTCWN can handle pressures up to 5000 psi (350 bar) at port 3, with pressure settings that remain stable regardless of back pressure at port 2. The valve's performance is relatively unaffected by changes in oil temperature or contamination levels. With a capacity of 60 gpm (240 L/min), it features a response time typically around 2 ms and a pressure ramp-up time between 300 to 500 ms. The main stage orifice is contamination-protected, while its floating-style construction minimizes risks of internal binding due to installation torque or machining variations. Installation requires specific torque values: 150-160 lbf ft (203-217 Nm) for the valve and 80-90 lbf in (9-10 Nm) for the locknut. The adjustment screw has an internal hex size of 5/32 in (4 mm), while the locknut hex size measures 9/16 in (15 mm). Weighing approximately 1.50 lb (0.70 kg), this cartridge also supports Viton seal kits under part number 990217006.

Pilot-operated, anti shock relief cartridges limit maximum system pressure and also limit the rate of pressure rise. The valve opens and then ramps closed at a constant speed, independent of settings and flows. The adjust screw determines the maximum (relief) setting and the minimum (threshold) setting.The external drain makes the valve insensitive to pressure at port 2.
- Because the modulating occurs inside the cartridge, these valves are immune to most of the problems associated with cavitation, namely noise and manifold erosion.
- 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.
- Not suitable for sequncing cylinders.
- Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar).
- Pressure settings are insensitive to back pressure at port 2.
- Will accept maximum pressure at port 2; suitable for use in cross port relief circuits.
- Valve is relatively insensitive to varying oil temperatures and oil borne contamination.
- Not suitable for use in load holding applications.
- When pressure at the inlet (port 1) exceeds the threshold setting, the valve opens to tank (port 2). The pilot section moves forward at a steady rate, increasing the setting by compressing the pilot spring. Maximum setting is achieved when the pilot section reaches a mechanical stop.
- The main stage orifice is protected against contamination.
- 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.
