Manual Gate Valves

DOYLES stocks both new and re-manufactured manual gate valves in common bore sizes and pressure ranges. A wide range of body and trim materials are also available to meet various operating conditions. All valves meet API 6A specifications and NACE MR0175 requirements to satisfy your service needs.

Hydraulic Gate Valves

Hydraulic gate valves are available with a manual closing and locking screw and the 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. Both our manual and hydraulic valves meet API 6A specifications and NACE MR0175 requirements to satisfy your sour service needs.
