The Sun Hydraulics RSDSKCN (RSDSKCN) is a pilot-operated, balanced poppet sequence valve designed to supply a secondary circuit with flow once the pressure at the inlet port 1 exceeds the valve setting. It effectively manages pressure at port 1 relative to the drain port 3 and remains unaffected by back pressure at port 2 up to the valve setting. This makes it suitable for load holding applications and cross-port relief circuits. The valve features a main stage orifice protected by a 150-micron stainless steel screen and can handle maximum pressures up to 5000 psi (350 bar). With its floating style construction, it minimizes internal binding issues due to installation torque or machining variations. The RSDSKCN model is interchangeable with other three-port sequence cartridges, maintaining consistent flow paths and cavity sizes within its series. The valve's response time is typically around 10 milliseconds, with maximum leakage at reseat being minimal at 10 drops per minute (0.7 cc/min). It allows for adjustment through five clockwise turns to increase the setting, with specific torque requirements for installation and locknut adjustments. Weighing only .30 lbs (0.15 kg), this valve incorporates Viton seals for reliable performance under various conditions. This model's design ensures immunity from cavitation-related issues such as noise and manifold erosion, making it a robust choice for regulating pressure in hydraulic systems where there is existing pressure in the return line. Its versatility in application is further enhanced by its ability to accept maximum pressure at port 2 without compromising performance, providing an efficient solution for maintaining desired pressure levels in complex hydraulic systems.

Pilot-operated, balanced poppet sequence valves will supply a secondary circuit with flow once the pressure at the inlet (port 1) has exceeded the valve setting. The pressure setting of a sequence valve controls the pressure at port 1 relative to the pressure at the drain (port 3). These valves are insensitive to back pressure at port 2 (sequence), 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).
- Suitable for use in load holding applications.
- 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.
