进口不锈钢蝶阀原理特点
进口不锈钢蝶阀是由橡胶密封蝶阀和碳钢或不锈钢阀板、阀杆构成，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.
Note: Please refer to “Numbering System” sheet to obtain detailed figure numbers.
Caution: All 2000 series valves must be installed in the partial open position. Installing in the full closed position may damage the seat during start up and void any warrantees.
