对夹式蝶阀

对夹式蝶阀由橡胶密封蝶阀和碳钢或不锈钢阀板、阀杆构成，采用对夹式安装方式。适用于温度≤80～120℃如食品、医药、化工、石油、电力、轻纺、造纸等给排水、气体管道上作调节流量和截流介质的作用。

Note: Seat materials are capable of withstanding lower temperatures without damage. However, the elastomer becomes hard and torques increase. Some flow media may further restrict the published temperature limits and/or significantly reduce seat life.

Options

Seats: Buna-N, EPDM, Hypalon, Viton, Neoprene, PTFE.

Disc: Nickel plated Ductile iron, nylon coated ductile Iron,

aluminum bronze, 316 stainless steel.

Body: Cast iron, ductile iron.
