Working principle and purpose of the product:

The ventilation butterfly valve has a small driving torque, flexible opening and closing, and easy operation. The valve body is equipped with a sealing ring, and there is no visible gap between the sealing pairs, resulting in a low leakage rate. The expansion gap between the butterfly plate and the valve body is large, which can effectively prevent jamming caused by thermal expansion and contraction. The TD41W handle operated ventilation butterfly valve produced by Shanghai High Valve can be equipped with various driving devices, such as manual device, turbine transmission device, starting device, and electric device. Ventilation butterfly valves are used in industrial pipelines such as metallurgy, petrochemicals, electricity, building materials, and mining to control or regulate medium gases.

Product Structure Features:

1. The D41W ventilation butterfly valve is manufactured by welding steel plates and has the characteristics of short structural dimensions, light weight, and easy installation.

2. This valve is designed and manufactured using a new structural form of welding a midline disc plate and a short structural steel plate. It has a compact structure, light weight, easy installation, low flow resistance, large flow capacity, avoids the influence of high temperature expansion, and is easy to operate.

3. No connecting rods, bolts, etc. inside, reliable operation, long service life. It can be installed in multiple workstations without being affected by the flow direction of the medium.
