Product characteristics
Can be equipped with handles, worm gears, electric or pneumatic controls.
Reduce rotary torque, support the stem, and allow it to effectively separate from the body, reduce stem wear.
After polishing, the valve seat precision is high.
Meet the requirement of zero leakage of air tightness test. Low opening and closing torque for extended valve seat life.
Stem seals are not easily deformed, thus avoiding common stem leaks.
The utility model has high precision and high strength and is suitable for mounting handles and other control devices.
The utility model is characterized by a valve stem and a valve plate firmly connected with the valve plate, and has the characteristics of anti-vibration and easy replacement.
High precision, high reliability, easy to control the opening and closing of the valve plate.
Good overall stability, stability, tension, leak proof.
Auxiliary shaft end leakage
Scope of application
Worm gear flanged butterfly valve is mainly used to adjust and cut off the fluid in the pipeline, using three eccentric multi-layer metal hard seal design structure. Its compact structure, light weight, simple operation, stable operation, widely used in water supply and drainage, chemical smelting, liquefied petroleum gas and urban construction and other engineering systems.
