• Shuttle valve senses the greater of two pressures
• Standard D03 interface on 16mm to 63mm sizes
• Standard orifice installed in X & A
• Removable orifice plug options
On/Off Check Valve
Will hold valve closed in one condition and serve as a check valve in the other condition.
Senses the greater of two pressures between the “X” pilot & the “A” pilot. The “X” pilot should be connected to the “B” port (side of insert) and the “Z1” port should be connected to the “A” port (nose of insert).
By using a standard D03 directional control with flow from “P to A” in the de-energized condition the shuttle will use the greater pressure to hold the valve closed. Energizing the solenoid prevents the shuttle from sensing the Z1 pilot, thereby establishing free flow from A to B & a check valve function from B to A
