Summary of Functions
The double eccentric soft seal butterfly valve is designed as bi-directional rubber sealing according to the American association of hydraulic AWWA C504, AWWA C 516 standard, BS EN593 standard, ISO 10631 standard and GB/T12238 standard. The main advantage is the good sealing performance, long service life, simple construction, convenient in disassembling and so on. and its widely used in water supply and drainage, water treatment, electric power, shipbuilding, chemical industry, medicine and other industrial area for shutting off, regulating and controlling flow.

Products Features
1. The double eccentric resilient-seated sealing construction. Zero Leakage in Bi-directional sealing test.
2. Excellent isolation function for liquid and gas and reliable flow control characteristics.
3. Easy to replace and adjust the elastic sealing ring to make sure good sealing performance.
4. Opening and closing fast, small torque, flexibly operation, energy saving.
5. Adjust the compaction of the sealing ring to make the sealing ring in the best condition to prolong the service life.

Construction Feature
For corrosive medium, double eccentric rubber lined type butterfly valve can be used to reduce the cost. the butterfly valve integrates the advantages of both concentric rubber lined butterfly valves and double eccentric soft seal butterfly valves. (Comparing to the concentric rubber lined butterfly valves, the service life of double eccentric rubber lined type butterfly valve is longer and it can be used for higher pressure.)

Instruction:
Eccentric 1: E- The eccentric between the center line of shaft and the center line of the body.
Eccentric 2: H- The eccentric between the center line of shaft and the center of the seat sealing surface.
Cone Angle: The inclination angle of the seat sealing surface.

Due to the double eccentric construction, in the process of opening, the disc of the valve get away from the seat gradually, the friction between the sealing surface is reduced, so that the service life is prolonged.
The designed body seat: For cast steel body, the body seat is Integral seat with welded layer of anti-corrosive material; For cast iron body, the body seat is replaceable seat
