The Welded Butterfly Valve adopts a triple eccentric structure. This valve is a bubble-grade metal seated butterfly valve in high temperature, high pressure, and fire protection applications. The valve can be operated by worm gear, pneumatic or electric actuators.
Welded Butterfly Valve
Welded ends avoid the bolted flange joints used by flanged connections, but welding alone does not establish permanent leak-free performance. Confirm the approved welding procedure, weld inspection and pressure or leakage testing requirements for the actual installation.
Size: 3”-60”

Frequently Asked Questions
What information do you need to match the welded ends to my pipe?
Provide the pipe material, outside diameter, wall thickness and required weld-end preparation, together with the applicable project specification. Request the selected valve drawing before finalizing the joint design.
Can I apply the same welding and heat-treatment procedure to every size of this valve?
Do not assume one universal procedure. Obtain the model-specific installation instructions and an approved project welding and heat-treatment procedure that addresses the valve materials and protection of its internal components.
What should I include when ordering the worm-gear configuration?
Specify the installation orientation, available operating space and required isolation duty, together with the medium and design conditions. Request confirmation of the complete valve and gearbox arrangement and its access requirements.
