Choke valve

Choke valve is mainly used in wellhead equipment, choke manifold or other high-pressure pipe line to throttle. Wellhead Choke Valve of SCOTON has the characteristic of simple structure. Bonnet is connected by hammering fig, which make it easy to remove and maintain on site. Complete hard-faced parts can improve valve's life service.

Main features are as follows

• Complete hard-faced parts are more anti-erosion than ordinary material, and has longer service life;
• Can be designed as double flange, thread of fig connection according to customers requirement;
• Easy to maintain, much easier to change parts on sites;
• The trim can be changed with adjustable choke valves of SCOTON, has flexible response capacity;
• The design of stem sealing covers all pressure class. Temperature class and all flow service which could be meet in wellhead and manifold;
• To ensure safety, pressure releasing valves are installed om positive choke valve, The parts could be changed in pipeline.
