The Sun Hydraulics RVISLQV (RVISLQV) is a ventable, pilot-operated, balanced-poppet relief cartridge designed for precise pressure regulation. This valve is typically closed and begins to open to the tank port when the inlet pressure reaches the preset level, effectively throttling flow to maintain desired pressure levels. It features a vent port that enables remote control via other pilot or 2-way valves, making it suitable for load-holding applications where zero leak valving on the vent port is essential. The RVISLQV can handle maximum pressure at port 2 and is ideal for cross-port relief circuits. With its design, this valve remains stable even with varying oil temperatures and contamination levels, thanks to its internal modulating mechanism that mitigates cavitation-related issues such as noise and manifold erosion. The main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and reliability. The valve's backpressure on the tank port adds directly to the valve setting at a 1:1 ratio. Its construction minimizes internal binding risks due to excessive installation torque or machining variations. The RVISLQV has a capacity of 120 gpm (480 L/min) and can operate at pressures up to 5000 psi (350 bar). Its response time is typically around 2 ms, with maximum leakage at reseat being minimal at 10 drops/min (0.7 cc/min). Adjustments can be made via an internal hex screw with specific torque requirements for optimal performance. Weighing in at 3.10 lb (1.40 kg), this robust valve includes a Viton seal kit for enhanced sealing capabilities in demanding conditions.
