The Sun Hydraulics SDHTCCN (SDHTCCN) is a pilot-operated, anti-shock relief cartridge designed to regulate maximum system pressure and control the rate of pressure rise effectively. This valve opens and ramps closed at a constant speed, independent of settings and flows, with an adjustable screw to set the maximum relief and minimum threshold settings. It incorporates an external drain, making it insensitive to pressure at port 2, thus suitable for use in cross port relief circuits. The valve is engineered to be immune to cavitation issues such as noise and manifold erosion due to its internal modulation. It features a maximum operating pressure of 5000 psi (350 bar) and can handle a flow capacity of up to 60 gpm (240 L/min). The SDHTCCN is relatively insensitive to varying oil temperatures and contamination, enhancing its reliability in demanding conditions. Notably, this valve is not suitable for sequencing cylinders or load-holding applications. When the inlet port 1 pressure exceeds the threshold setting, the valve opens to tank port 2, with the pilot section moving forward steadily to increase the setting by compressing the pilot spring until a mechanical stop is reached. The design includes Sun's floating style construction, minimizing internal part binding risks due to excessive installation torque or cavity/cartridge machining variations. Installation requires specific torque settings: 150-160 lbf ft (203-217 Nm) for the valve hex size of 1 1/4 in. (31.8 mm). Additionally, it offers a rapid response time typically around 2 ms and a pressure ramp-up time between 300-500 ms. The model weighs approximately 1.50 lb (0.70 kg), with Viton seal kits available under part number 990217006 for enhanced durability against various hydraulic fluids.

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.
