The Sun Hydraulics SDHTCAN (Material Number: SDHTCAN) is a pilot-operated, anti-shock relief cartridge designed to limit maximum system pressure and the rate of pressure rise. This valve opens and ramps closed at a constant speed, independent of settings and flows. The adjustment screw allows for setting the maximum relief and minimum threshold levels. An external drain ensures the valve's insensitivity to pressure at port 2, making it suitable for cross-port relief circuits but not for sequencing cylinders or load-holding applications. With a capacity of 60 gpm (240 L/min) and a maximum operating pressure of 5000 psi (350 bar), this cartridge is relatively insensitive to varying oil temperatures and contamination. The valve features Sun's floating style construction, minimizing internal binding risks due to torque or machining variations. It incorporates a main stage orifice protected against contamination and offers a typical response time of 2 ms with a pressure ramp-up time between 300-500 ms. Installation requires specific torque values: valve installation torque ranges from 150-160 lbf-ft (203-217 Nm), while locknut torque is set between 80-90 lbf-in (9-10 Nm). The cartridge includes an adjustment screw with an internal hex size of 5/32 in (4 mm) and requires up to five turns clockwise to increase the setting. The SDHTCAN model weighs approximately 1.50 lb (0.70 kg) and utilizes Viton seals, with seal kit part number 990217006 available for maintenance needs.

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.
