304 316L Stainless Steel Sanitary Welding Butterfly Valve Butt Welding Valve

Butt welding butterfly valve is a national key new product. The high-performance manual butterfly valve adopts a double eccentric and a special oblique cone oval sealing structure. It solves the shortcoming of the traditional eccentric butterfly valve that the sealing surface is still in sliding contact friction at the moment of opening and closing 0°~10°, and the sealing surface of the butterfly plate is separated at the moment of opening, and the effect of sealing when the contact is closed, so as to extend the service life and maximize the sealing performance. Good purpose.

Welded butterfly valve are valves with a circular body and a rotary motion disk closure member which is pivotally supported by its stem. Buterfly valve is either remote-controlled by means of an actuator or manually operated by means of a handle. The handle for manual operation mechanically locks the valve in its full open, half open and closed position. By rotating the handle, the motion disk either parallel or perpendicular to the flow of water, shutting off the flow. The actuator is designed so that an axial movement of a piston is transformed into a 90° rotation of a shaft. The torque of the actuator is increased when the valve disc contacts the seal ring of the butterfly valve.
