The Sun Hydraulics RVGSCNV (Material Number: RVGSCNV) is a ventable, pilot-operated, balanced poppet relief cartridge designed as a normally closed pressure regulating valve. When the inlet port pressure reaches the valve setting, it opens to the tank port, throttling flow to regulate pressure. This model features a vent port for remote control by other pilot or 2-way valves. It is known for its accuracy, low pressure rise versus flow, smooth operation, quiet performance, and moderate speed. The internal modulation makes it resistant to cavitation issues such as noise and manifold erosion. It is suitable for load holding applications when any valving on the vent port is zero leak. The cartridge can handle maximum pressure at port 2, making it appropriate for cross-port relief circuits. A remote pilot relief on the vent port controls the valve below its own setting. It performs reliably despite varying oil temperatures and contamination levels. The main stage orifice is protected by a 150-micron stainless steel screen. Back pressure on the tank port adds directly to the valve setting at a 1:1 ratio. The floating style construction minimizes binding due to excessive installation torque or machining variations. Specifications include a T-17A cavity configuration with Series 3 capacity of 50 gpm (200 L/min) and maximum operating pressure of 5000 psi (350 bar). 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 and maximum leakage at reseat of 10 drops/min (0.7 cc/min). Adjustment requires approximately five clockwise turns to increase settings, with specific torque requirements for installation and adjustments provided in detail.
