API 6A Positive Choke Valve for Christmas Tree
FC Gate Valves' feature:
'FC type Gate Valve is the valve that provides reliability and interchangeability.
The 'FC' valves is non-rising stem and has bidirectional sealing making it ideally suited for Manifolds, X-mas trees in drilling and oil production field.
The surface of the gate and the seats are TC alloy spray welding to against corrosion, abrasion, erosion, etc
The slab-gate design provides a metal-to-metal seal on the flow stream and the bolted bonnet provides for ease of maintenance and repair.
The Stem pin protects the stem and internal parts from failure by shearing if the handwheel is over-torqued
Single gate helps to prevent line sediment from entering the body cavity and prevents pressure locks when the upstream pressure drops.
A wide range of body and trim material is available to meet various operating conditions.
Hydraulic Actuators type valve can be used on Manifold or other remote control system.
Union connection makes installation and dismounting convenient.
The automatic open/close of valve is realized through a spring without shutting down the system for protection, with a better performance than shear type safety valve.
The value ofpressure release can be adjusted.
