The Sun Hydraulics SQHBKAN (SQHBKAN) is a kickdown sequence valve designed to create an unrestricted flow path from port 1 to port 2 once the pressure at the inlet port 1 exceeds the valve setting. The valve remains open as long as the pressure at port 1 surpasses that at port 2. Resetting occurs when pressure at port 1 falls below the set level, flow ceases, and pressure at port 2 is equal to or greater than at port 1. This valve should not be used in load-holding applications and is intended for use on the actuator side of a system, requiring cessation of flow for resetting. The main stage orifice is protected by a 150-micron stainless steel screen, and pressure at port 3 should not exceed 5000 psi (350 bar). Featuring Sun's floating style construction, it minimizes binding due to excessive installation torque or machining variations. It fits into cavity T-17A, Series 3 with a capacity of up to 60 gpm (240 L/min) and has a factory-set kickdown point with a maximum operating pressure of 5000 psi (350 bar). The typical response time is around 25 ms, with maximum leakage rated at 4 in\u00b3/min (65 cc/min) under specific conditions. Adjustments can be made by turning clockwise up to five turns to increase settings. Installation requires a torque of between 150-160 lbf ft (203-217 Nm), with locknut torque specified between 80-90 lbf in (9-10 Nm). The valve weighs approximately 1.50 lb (0.70 kg), and it comes equipped with Viton seals as standard through cartridge seal kit number: 990017006.
