Handwheel wafer butterfly valve

Overview:

A manual butterfly valve is composed of a valve stem, valve body, valve plate, valve seat and handle, etc. Rotate the handle to pass it on to the valve stem, causing the valve plate to rotate and thereby changing the on-off state of the valve. The soft sealing design and structure of the valve seat enable the valve to have good sealing performance in the closed state, and it is widely used in the fluid control system in the industrial production process.
