Hunting’s Dual Pilot Valve, specifically designed for use in Intervention Workover Control Systems (IWOCS).
The DPV controls both the open and closing side of the BOP, while eliminating numerous valves from the operation.
The valve routes input from a single hydraulic supply to either of two function circuits, depending on pilot signal.
The other function circuit is routed to vent. In an IWOCS, these two function circuits open and close the BOP.
4-way, 2-position directional-control valve, which can also be configured as a 3-way, 2-position directional-control valve
Dual pilot circuits for redundancy
7,500-psi working pressure supply and function circuits; 6,000-psi pilot circuits
Manufactured from high-strength stainless steels
Sliding metal seals
Extensively tested in-house to ensure more than 10,000 leak-free cycles
Qualification report available on request
Available standard with JIC-12 (f) supply and function connections and JIC-6 (f) pilot connections. Other end connections are available upon request.
Resists dirty fluid
Long, leak-free operation
Reduces number of SPM valves and regulators
Provides redundancy to offset potential pilot signal failure
One DPV can eliminate all shuttle valves from the BOP circuit
