Our company's electric flange extendable stem butterfly valve can be extended by adding a length, which can be determined according to the usage requirements. The electric flange extendable stem butterfly valve is a multi-layer metal-sealed butterfly valve with a three-seal eccentric structure, which reduces the wear between the valve seat and the valve plate sealing ring, thereby increasing the service life and sealing performance of the valve. The butterfly valve with a three-seal eccentric structure has the characteristic of becoming tighter as it closes, with the best sealing performance and zero leakage. When opened simultaneously, it ensures that the sealing surfaces are separated from contact, protecting the sealing surfaces from friction damage. 

The performance of the electric actuator complies with the provisions of JB/T8528-1997 (Technical Conditions for Electric Actuators of Ordinary Valves). The performance of the explosion-proof type complies with the provisions of GB3836.1-2000 (Part 1 of Electrical Equipment for Explosive Gas Atmospheres: General Requirements), GB3836.2-2000 (Part 2 of Electrical Equipment for Explosive Gas Atmospheres: Explosion-proof Type "d") and JB/T8529-1997 (Technical Conditions for Explosion-proof Electric Actuators).

The application scope of the electric flange extension rod butterfly valve includes: 

Industrial field: Applicable to light and heavy industries such as chemical, petrochemical, petroleum, papermaking, etc., as well as building pipelines.
