EPDM is the abbreviated name for Ethylene Propylene Diene Monomer. In general industry, one may see other abbreviations or trade names used in lieu of EPDM such as EPT, Nordel, ECD, or EPR. All of these are the same materials as EPDM. EPDM is a standard seat material offered in Bray resilient-seated butterfly valves.

Flanged Butterfly valves These Flanged Butterfly valves with flanges on both ends. The flange ends connect with the flanges on the pipeline by bolts.  Lug-Style Butterfly valves A Lug-Style Butterfly valve has the function of reducing pressure rating.  Welded Butterfly valves Butt Weld Butterfly valves and Socket Weld Butterfly valves are two commonly used Welded Butterfly valves. These kinds of valves are of the enclosed type, helping to both on-off and regulate service.   Parts of EPDM Butterfly Valve    Parts Material  Body Cast iron, Ductile iron, WCB  Seat EPDM, NBR, VITON, PTFE  Disc Nickel ductile iron, AI bronze, Stainless Steel  Stem Stainless Steel, Monel  Bushing PTFE  &#8220;O&#8221; ring PTFE  Pin Stainless Steel  Key Stainless Steel    Advantages of EPDM Butterfly Valve  Butterfly valves are similar to ball valves but have more advantages. They are open and close very quickly when actuated pneumatically. The disc is lighter than a ball, and the valves require less structural support than a ball valve of comparable diameter. Butterfly valves are very precise, which makes them advantageous in industrial applications. They are quite reliable and require very little maintenance.  Turning on\/off easily and rapidly with less force. Having less fluid resistance and can be operated frequently. Simple structure, small size, and short face-to-face dimension, which are suitable for large-diameter valves. It can be used for transmitting mud, fewer liquids are stored at the apertures of the pipe. Long service life. Standing the test of tens of thousands of opening\/closing operations. Butterfly valves have excellent regulation performance. Small torque. The pressure on discs at the two sides of the spindle is almost equal, causing contrary torque. Thereby, the valves can be opened with less force. A sealing face is generally made of rubber or plastic. So the butterfly valves can be with good sealing under low pressure.
