Dual phase steel butterfly valve opening and closing is a disc-shaped butterfly plate, the body rotation around its own axis, so as to achieve open/close or regulating valve butterfly valve. Dual phase steel butterfly valve fully open to the barrier is usually less than 90 degrees, butterfly valve and the adjustment lever itself not powerful, self-locking to butterfly plate positioning, to add worm gear reducer on the valve stem. The use of worm gear reducer, can not only make the butterfly plate with self-locking ability, make the butterfly plate to stop at any position, also can improve the performance of the valve. Dual phase steel butterfly valve USES the nickel metal forging compound craft manufacture, nickel alloy valve stem and pin, silicon carbide bushings, corrosion resistant, reliable and good performance. Dual phase steel butterfly valve products are widely used in the transmission process of corrosive medium.

The characteristic of dual phase steel butterfly valve

(1) three unique to the eccentricity of the design between the sealing surface friction drive, prolong the service life of the valve.

(2) the dual phase steel butterfly valves produced by torque elastic seal.

(3) clever wedge design allows for automatic sealing valve has closed more and more tightly, compensatory, zero leakage between the sealing surface.

(4) small volume, light weight, light, easy to install dual phase steel butterfly valve operation.

(5) according to user requirements with pneumatic, electric devices, meet the needs of the remote control and programmed control.

6 replacement parts material can be applied to all kinds of medium.

All landowners continuous structure diversification: the clamp, flange, butt welding
