Product Detail:

What is Soft seat butterfly valve ?

Soft seat butterfly valve is a valve used for flow regulation in large pipe diameters in which the disc takes the form of disk. Operation is similar to that of a ball valve. A plate or disc is positioned in the center of the pipe. The disc has a rod passing through it that is connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, therefore a pressure drop is always induced in the flow, regardless of valve position.

Soft seat butterfly valve suitable for corrosive and abrasive process media in liquid, powder, or gas state Shut-off, flow control and throttling.

Our advantages of Soft seat butterfly valve

Compact construction results in low weight, less space in storage and installation.

Centric shaft position,100% bi-directional bubble tightness,which makes installation acceptable at any direction.

Full bore body gives low resistance to flow.

Low operating torques results in easy operation and economical actuator selection.

PTFE lined bearings are disigned for anti-friction and wear,no lubrication is required.

Inserted lining to the body, liner easy to replace,no corrosion between body and lining, suitable for end of line use.
