High-performance double eccentric butterfly valve
Product description
Wide application fields:
1.Petroleum,Chemical industry,natural gas;
2.Power station,water treatment ;
3.Iron and steel metallurgy;
4.Light industry machinery;
Technology Strength:
1.DN50/2“-DN600/24”
2. Applicable temperature:-46~425℃
3.PN10/16/25/40.ANSI cl.150/300（DN50-600）
4.Connection way: Wafer,lug
5. Shaft seal meet the requirement of TA-LUFT（Germany standard）
6. Special seal-compensation packing design can stop the valve from leakage effectively.
7. Actuator mounting based on the standard ISO5211,make sure the actuator and shaft turn
8.The seat with automatic compensation function provide a reliable seal,which can be used for the working condition with the vacuum degree more than 38mmHg in a synchro way
Features:
1. Special actuator assembly flat according to ISO5211: Easy to assemble with actuator and laegely decrease the cost for assembling actuator and valve.
2. Coaxial ring design used for connect actuator and valve: Can avoid shaft offfset that would cause abrasion in early stage, which can boost the valve's seal
performance and lifetime.
3. Special shaft design of preventing the shaft from flying out: The upper shaft with step structure can prevent the shaft from being blew out due to the incidental
fracture.（See figure B,point a）.
