We Keep Bulk Stock of ASTM A216 Gr. WCB Wafer Type Butterfly Valve at our stockyard, contact us for Free Sample of ASME B16.34 Butterfly Valve Lug Type

Wafer Type Butterfly Valve maintains the sealing against the walls of the valve. This avoids the backflow of the fluids inside a piping system. The Lug And Wafer Type Butterfly Valves  are used for different application types. The lug type has threaded inserts at both sides of the valve body. So they could be easily installed into a system with just two bolts and nuts. The Wafer Type Butterfly Check Valve can also come in concentric, doubly eccentric and triply eccentric types. These have their differences in applications as well. The concentric ones have a resilient rubber seat with a metal disc. The doubly eccentric type has high performance and it uses different materials for the seat and the disc.

The Wafer Type Triple Offset Butterfly Valve has seats laminated or in solid metal. The wafer style valves have tightly fitting seal or gasket that prevents backflow and allows for unidirectional flow. The o-ring or gasket is precision machined. The valve also has flat faces on the upstream and downstream.

What is Wafer Types Butterfly Valve?

The Wafer Lug Type Butterfly Valve is made from different material types ranging from duplex steel to alloy steel and in ordinary austenitic stainless steels. The sizes and dimensions of the valves differ as well. They range from ½ inches to 48 inches with pressure capacities ranging up to 2500lbs. There are also rotary valves which belong to the family of butterfly valves.
