HYDRAULIC SHUTTLE VALVES
HYDRAULIC SHUTTLE VALVES
Parker’s sequence valves are used to control the sequence of operation of two or more hydraulic actuators. The sequence valve pressure is set higher than the first actuator operation pressure. Once the first actuator has completed its cycle, the sequence valve opens, allowing the second actuator to move. Parker’s line of pilot-operated sequence valves include a series of internally piloted, externally drained valves and a series of externally piloted, internally vented valves.
HYDRAULIC SHUTTLE VALVES INCLUDE
Parker’s ball type inline shuttle valves are plumbed external from manifolds and line bodies and are available in two flow size options of 11 lpm (3 gpm) or 22 lpm (6 gpm), and pressures up to 207 bar (3000 psi).
ASHX Series

Additional Technical Insight:
The valve consists of a steel ball that can seal against one of two adjacent seats, providing a path from the highest pressure signal to another function. When one inlet port is pressurized, the ball or poppet is forced against the opposite seat, blocking that inlet and providing a flow path to the outlet port.
