The Sun Hydraulics RSJSKNV (RSJSKNV) 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 regulates pressure at port 1 relative to the drain port 3, remaining insensitive to back pressure at port 2 up to the valve setting. This makes it suitable for use in cross port relief circuits and as an alternative to two-port relief valves if there's pressure in the return line. The valve's design ensures interchangeability across all three-port sequence cartridges, maintaining consistent flow paths and cavity dimensions for a given frame size. The RSJSKNV features a main stage orifice protected by a 150-micron stainless steel screen and incorporates Sun's floating style construction, minimizing internal binding due to excessive torque or machining variations. It can handle a maximum operating pressure of 5000 psi (350 bar) and has a capacity of 120 gpm (480 L/min). The control pilot flow ranges from 15 to 20 in\u00b3/min (0.25 to 0.33 L/min), with a typical response time of 2 ms. This valve is designed for durability with maximum valve leakage at reseat limited to 10 drops/min (0.7 cc/min). The adjustment mechanism allows for five clockwise turns to increase settings, with specific torque requirements for installation and locknut adjustments. Weighing in at 3.10 lb (1.40 kg), it comes equipped with Viton seals as part of its cartridge seal kit, ensuring reliable performance under various conditions. Overall, the Sun Hydraulics RSJSKNV sequence valve offers robust performance in managing hydraulic pressures and flows while providing versatility through its interchangeable design and high-pressure tolerance capabilities.

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).
- 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.
