Bidirectional pressure butterfly valve, butterfly valve

Characteristics of the Bidirectional Pressure Butterfly Valve

Since this product's butterfly valve adopts a three-dimensional eccentric principle design, the spatial movement trajectory of the sealing surfaces is made ideal. There is no friction or interference between the sealing surfaces, and with the appropriate selection of sealing materials, the sealing performance, corrosion resistance, high-temperature resistance and wear resistance of the butterfly valve have been reliably guaranteed. Its main features are as follows: 

1. The opening torque is small, it is flexible and convenient, and saves effort and energy.

2. The three-dimensional core structure enables the butterfly plate to close tighter and tighter, and its sealing performance is reliable, achieving zero leakage.

3. It is resistant to high pressure, corrosion, wear, and has a long service life, etc. 

The two-way pressure butterfly valve adopts the standard.

The two-way compression sealing butterfly valve is widely used in industries such as petroleum, chemical engineering, power, metallurgy, food, medicine, light industry, papermaking, etc. It can be installed on industrial pipelines with a temperature of ≤ 425℃ and the medium being gas, air, steam, water, seawater, oil products, etc. for regulating flow and cutting off the medium. The driving forms include manual, worm gear transmission, pneumatic, hydraulic, electric, electro-hydraulic linkage and other actuators, which can achieve remote control and automatic operation. Its structure is designed based on the three-dimensional core principle, and the valve seat adopts a multi-level structure of hard and soft sealing compatibility. The processing and technology. This product is composed of main components such as valve body, butterfly plate, multi-level valve seat, valve stem, transmission mechanism, etc. Therefore, it is widely applied in pipelines with corrosive media such as metallurgy, power, petroleum, chemical engineering, air, gas, flammable gas, and water supply and drainage.
