Double Eccentric Butterfly Valve
Double Eccentric Butterfly Valve Specifications
The Double Eccentric Butterfly Valve adopts a double-offset disc design, which allows the disc to move away from the valve seat, thereby reducing operating torque and valve seat wear. Double eccentric butterfly valve operation can be done by gearbox and handwheel or electric, pneumatic or hydraulic actuators. Tested to comply with DIN3202, DIN2501 PN10/PN16 standards. This ensures the highest quality available. Dual offset disc design reduces torque and valve seat wear
The butterfly valve should be designed specifically for water plant applications and should be a double offset design. Zero and single offset butterfly valve designs are unacceptable. The valve should exceed the requirements of PN10. The valve should conform to the size and grade specified in the valve table. All valves should be airtight valves, the size is suitable for two-way water supply, full rated pressure
