VIS Hydraulics SQA0.G38

Direct acting in-line sequence valve with steel housing. The SQA combines in one easy-to-install in line valve the typical function ofshock relief and anticavitation through the check valve. In the pressure relief function it provides very low pressure rise thanks to thesmart deflector design. When the pressure at the high pressure inlet (2) reaches the valve setting, the valve starts to open to tank(1). In the free reverse flow function a very light bias spring allows for ease of flow passage from nose to side (1 to 2). Highprecision machining guarantees quick response to load changes, limited hysteresis and reduced leakage.
