The Sun Hydraulics SQJBCEV (SQJBCEV) is a kickdown sequence valve designed to provide an unrestricted flow path from port 1 to port 2 once the pressure at the inlet port exceeds the valve setting. This valve is specifically engineered for applications where it is necessary to maintain open flow as long as the pressure at port 1 remains higher than at port 2. It features a floating style construction, which helps prevent internal binding due to installation torque or machining variations. The main stage orifice is protected by a 150-micron stainless steel screen, ensuring durability and reliable performance. The SQJBCEV should not be used in load holding applications and is intended for use on the actuator side of a hydraulic system, where flow must cease for the valve to reset. This model has a maximum operating pressure of 5000 psi (350 bar) and offers a capacity of up to 120 gpm (480 L/min). The response time is typically around 25 ms, with maximum valve leakage at specified conditions being minimal at 5 in\u00b3/min (80 cc/min). The valve's adjustment can be modified with up to five clockwise turns to increase the setting, and it incorporates specific hex sizes for both the adjustment screw and locknut. The installation torque ranges between 350 - 375 lbf ft (474 - 508 Nm), ensuring secure placement within its designated cavity. Additionally, this model weighs approximately 3.10 lb (1.40 kg) and comes with an available Viton seal kit for enhanced sealing capabilities under various conditions.
