6 Inch Stainless Steel 304 Body Disc Seat EPDM Wafer Type Butterfly Valves Pneumatic Actuator Butterfly Valve

6 Inch Stainless Steel 304 Body Disc Seat EPDM Wafer Type Butterfly Valves Pneumatic Actuator Butterfly Valve

The wafer style butterfly valve is designed to maintain a seal against bi-directional pressure differential to prevent any backflow in systems designed for unidirectional flow. It accomplishes this with a tightly fitting seal; i.e., gasket, o-ring, precision machined, and a flat valve face on the upstream and downstream sides of the valve.

Lug-style valves have threaded inserts at both sides of the valve body. This allows them to be installed into a system using two sets of bolts and no nuts. The valve is installed between two flanges using a separate set of bolts for each flange. This setup permits either side of the piping system to be disconnected without disturbing the other side.

A lug-style butterfly valve used in dead end service generally has a reduced pressure rating. For example a lug-style butterfly valve mounted between two flanges has a 150 psi pressure rating. The same valve mounted with one flange, in dead end service, has a 75 psi rating.

Product advantages:

The product side flanges comply with national, German, Russian, American, British and Japanese standards and other domestic and international standards for multiple pressures, easy connection and wide adaptability, which can reduce the type of purchase and stock.

Wafer Handle Butterfly Valve Features :

(1). This valve has a tighter sealing function as it closes, and its sealing performance is reliable.
(2). The sealing material is made of nitrile and oil resistant rubber, which has a long service life.
(3). The rubber sealing ring can be located on the valve body or on the butterfly plate, which can be applied to different characteristics of media for users to choose.
(4). The butterfly plate adopts a frame structure with high strength, large flow area and small flow resistance.
(5). The overall baking varnish can effectively prevent corrosion and can be used in different media as long as the sealing material of the sealing valve seat is replaced.
(6). This valve has a two-way sealing function. It is not controlled by the flow direction of the medium during installation and is not affected by the spatial position. It can be installed in any direction.
(7). This valve has unique structure, flexible operation, labor saving and convenient.
