The FC gate valve features a non-rising stem with a slab gate, Full-Bore Thru-Conduit Design, Floating Slab Gate and Seats, floating seat ring body bushing design to provide safe dependable service. It is available in flanged or threaded ends in standard bore sizes from 1-13/16” thru 7-1/16” in working pressures of 5,000 psi thru 15,000 psi wp. Seat rings, body bushings, gate, stem are easily replaced in the field, Simple routine maintenance program limits repairs, eases operation, protects against corrosion, and extends service life.
The FL Gate Valves have earned a reputation in all types of applications. They are full-bore, through-conduit valves with forged bodies and slab gates. FL valves feature a single spring-loaded, pressure-energized, non-elastomeric lip seal. This seal assists in low pressure sealing and protects against contaminants.
The PFA gate valve features a non-rising stem with a slab gate, are vailable in temperature classes L, P, R, S,T, and U specified in API 6A, gate valves to be used in the X or Y high temperature can be supplied on request.
The FC 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.
The PFY hydraulic gate valves are widely used in the automatic control systems and remote control systems, featuring the hydraulically controlled opening and closing, stable performance and easy opera
The hydraulic or air drive safety valve, as executive part of safety system on well, can classify both parts of preparation valve and driver.
High pressure oil enters the empty chamber of the driver and then press the bottom spring as to open the valve, if the pressure exceed the bearing ability of wellhead assembly, by the sigh part through the sensor, the control mechanism unload the pressure out of the oil cylinder, and the spring pushes the valve stem to close the valve and wellhead assembly so as to ensure equipment safe.
The expanding gate valve features a non-ring stem with an expanding gate design to provide safe, dependable service in a variety of environments, It’s a available in flanged or threaded ends in standard bore sizes from 2-1/16” thru 4-1/16” in working pressures of 3000psi thru 5000psi. Full-Bore Design: Maximizes valve service life.
