1/2″ To 4″ Food Grade DIN Threaded Butterfly Valve With Pull Handle

The sanitary round thread butterfly valve is a valve that uses a circular butterfly plate as an opening and closing part and rotates with the valve stem to open, close and adjust the fluid passage. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°. When the rotation reaches 90°, the valve is fully opened.
