A multi-turn valve with a closing element that moves perpendicularly to the valve body seat and generally seals in a plane parallel to the direction of flow. This type of valves is suited both to throttling and general flow control.
Structure Type: With Bypass Pattern, without Bypass Pattern
Operated Way: Lever, Gear, Pneumatic, Electric
2. Y-pattern Globe Valve
Y-Pattern valves are available in three bonnet designs. The first design is the Bolted Bonnet, with male-female joint, spiral wound gasket, made in F30L/graphite. Ring joint gaskets are also available on request. The second design is the welded bonnet, with a threaded and seal welded joint. On request a full penetration strength welded joint is available. The third design is the pressure seal bonnet, with a threaded and pressure seal bonnet joint.
The Y-Pattern valves are available in globe and check design configurations.
