Description
Double eccentric end-flanged resilient sealing butterfly valve is operated by the disc rotating from 0° to 90 ,can be applied to cutoff of regulate the flow of media Vitreous be actuated by available upon request. Valve can be actuated by operating ever. handle wheel. electric actuator or pneumatic actuator.
Technical Specifications: 
Design: EN593
Face to face: ISO5752/EN558 SERIES13
Flange drilling: EN1092
Upper flange connection:ISO5211

Professional Design:
* When initating the rotary opening movement the disc is off-seated after only few degree of opening movement and there is very little wear and tear between seat ring and disc
* Body surface welding Brass when DN >700(see the picture),Our factory car also manufacture extension stem butterfly valve, butterfly valve of DN1800 extension stem lengthened 16.5 meters.
* Rubber sealing ring and disc can adjust tightness or softness with clamping ring, it insures best performance of adjusting the compression of sealing
* Body and disc made of ductile iron which promote the impact resistance and pressure-bearing capacity; sealing ring made of rubber and valve seat's sealing surface is conical shaped,make the sealing               capacity more reliable.
