The Sun Hydraulics SCGACWV (SCGACWV) is a direct-acting sequence valve with an integrated reverse-flow check valve, designed to supply a secondary circuit with flow once the inlet port 1 pressure surpasses the valve setting. This model ensures reverse flow from port 2 to port 1 via its integral check valve. It controls pressure at port 1 relative to the drain port 3 and requires connection of port 3 to maintain proper pressure reference in the control chamber. Blocking port 3 can lead to malfunction due to seal weepage. The pressure at port 3 should not exceed 5000 psi, as it is additive to the valve setting at a 1:1 ratio. The SCGACWV is suitable for load-holding applications and incorporates Sun's floating-style construction, reducing internal part binding risks due to excessive torque or machining variations. This sequence valve fits into a Cavity T-17A series and has a capacity of up to 60 gpm (240 L/min). It operates effectively under maximum pressures of up to 5000 psi (350 bar) and has typical response times of around 2 ms. The maximum leakage at reseat is limited to 10 drops/min (0.7 cc/min), and it features a check cracking pressure of approximately 25 psi (1.7 bar). The adjustment mechanism allows for increasing settings through five full clockwise turns, with specific dimensions for installation torque and adjustment screws provided for accurate setup. The model weighs approximately 1.50 lb (0.70 kg) and utilizes Viton seals, available under seal kit number: 990017006, ensuring durability and reliability in various hydraulic applications.
