Three-eccentric multi-layer Metal Butterfly Valve
ˇ¤Structure & Performance
ˇ¤Structure

The series of multi-layer metal-to metal butterfly valve is the new one wiht long lifetime and energy eccomized .The seat is designed according to the three-dimensional principle,the compatible to sotf sealing and metal multi-layer structure,with best designed according to the three-dimensional principle,the compatible to soft sealing and metal multi-layer structure,with best designed according to the three-dimensional principle,the compatilble to soft sealing and metal multi-layer structure,with best machinign and advanced technology.And the valve is mainly made pu of body,disc,multi-layer seat,stem and actuator.

ˇ¤Features

The butterfly valve has the ideal sealing track because of following three-eccentric principle,without friction and intererence between sealing sets,and also adopts the proper material,which make the butterfly valve have the reliable sealing ability,corrosion resistant,temperature resistant,and wearing resistance.The main features as bellow:
1.Small open torque,flexible,convenient,labor saving and energy economized.
2.Three-eccentric structure to make the disc mor and more tighter,with reliable sealing ability and on leakage.
3.High pressure resistant,corrosion resistant,wearing resistance,long lifetime.
