The Sun Hydraulics RSJSLBV (RSJSLBV) is a pilot-operated, balanced poppet sequence valve designed to manage the flow in secondary circuits once the inlet port pressure surpasses the valve's setpoint. Specifically engineered for precision and reliability, this valve controls pressure at port 1 relative to the drain port 3, remaining unaffected by back pressure at port 2 up to its setting. It can serve as a substitute for two-port relief valves when there's pressure in the return line. Notably versatile, all three-port sequence cartridges from Sun Hydraulics are interchangeable, featuring identical flow paths and cavity dimensions for a given frame size. As the inlet pressure at port 1 increases relative to the drain at port 3, pilot flow correspondingly rises above the valve setting. With a maximum operating pressure of 5000 psi (350 bar), this valve incorporates a main stage orifice protected by a 150-micron stainless steel screen. The design ensures that modulating occurs within the cartridge, rendering it immune to cavitation issues such as noise and manifold erosion. The RSJSLBV is well-suited for cross-port relief circuits due to its capacity to accept maximum pressure at port 2. It features Sun's floating style construction, minimizing risks of internal binding from excessive installation torque or variations in cavity/cartridge machining. The valve supports a capacity of up to 120 gpm (480 L/min) with factory settings established at 4 gpm (15 L/min). Its response time is typically around 2 ms with minimal leakage upon reseat. Installation requires specific torque values and adjustments can be made via an internal hex screw. This robust product weighs approximately 3.10 lb (1.40 kg) and utilizes Viton seals for enhanced durability under various conditions.
