Seat hydraulic directional control valve 9613

hydraulically-operated

Sequence valves control the order of events within a hydraulic system by directing pressure to the two circuits in a pressurecontrolled sequence. For example, this allows clamps to be actuated before work supports are locked. Initially, the valve is closed. Oil flows to the primary circuit until pressure reaches the valve setting. The valve then opens to deliver oil to the secondary circuit while holding pressure on the primary circuit. Once secondary and primary pressures are equal, the pressure increases uniformly in both circuits. There is no reduction of pressure available to either circuit. • Will not reduce pressure to the secondary circuit • Minimum operation pressure should be 120% of sequence pressure setting • Internal check valve allows free flow in reverse direction • Suitable for single- and double-acting circuits • NPT, SAE or manifold mounting
