Flanged Stainless Steel Turbine Butterfly Valve

The flange type stainless steel turbine butterfly valve is a type of valve that uses a circular butterfly plate as the opening and closing element and rotates with the valve stem to open, close, and regulate the fluid. The turbine butterfly valve not only has a simple structure, small volume, light weight, and low material consumption, but also has small driving torque, effortless operation, and fast opening and closing. It has good flow regulation function and closing sealing characteristics. The streamlined design of the butterfly plate reduces fluid resistance loss, making it an energy-saving valve.

The flange type stainless steel turbine butterfly valve stem is a through rod structure, which has undergone quenching and tempering treatment, and has good comprehensive mechanical properties, corrosion resistance, and scratch resistance. When the butterfly valve is opened and closed, the valve stem only rotates without lifting, and the packing of the valve stem is not easily damaged, ensuring reliable sealing.

The flange type stainless steel turbine butterfly valve is usually less than 90 ° when fully opened to fully closed. The butterfly plate and butterfly stem themselves do not have self-locking ability. In order to position the butterfly plate, a worm gear reducer needs to be installed on the valve stem. By using a worm gear reducer, not only can the butterfly plate have self-locking ability and stop at any position, but it can also improve the operational performance of the valve.
