D-FC Hydraulic Gate Valve
D-FC hydraulic gate valves are modeled after the OEM Model FC hydraulic gate valve. All dimensions are interchangeable with the original Model FC.
- DOYLES D-FC hydraulic gate valve is available with a manual closing and locking screw.
- Adjusting nut in the blind cylinder head absorbs the overload or test pressures applied to the opening side of the valve, preventing the pressure from reaching the stem.
- Cylinder head allows the piston to cover the exhaust port before the end of the stroke. This arrangement provides enough damping to protect the valve from shock loading.
- The overload or test pressures applied to the closing side of the cylinder are absorbed by the piston bottoming out against the packing gland of the stem.
- The tail rod and the operating stem have back seating shoulders to allow changing the stem packing while the valve is under pressure.
- Cylinder-operated valves have a special body containing a stuffing box through which a tail rod passes from the gate. The tail rod serves the following purposes:
- Acts as a pressure balance for the stem which connects the gate to the operating piston.
- Compensates for the volume displaced by the operating stem.
- Guaranteed to be 100% interchangeable with the OEM model.
- DOYLES D-FC hydraulic gate valves meet or exceeds API 6A standards.
