Two-Way Butterfly Valve
Ovonic butterfly valve is widely used in petroleum, chemical, electric power, metallurgy, food, medicine, textile, papermaking and other industries. It can be installed at a temperature of ≤425℃, and the medium is gas, air, steam, water, seawater, oil and other industries. The pipe network is used to adjust the flow and cut off the medium.
The driving forms include manual, worm gear, pneumatic, hydraulic, electric, electro-hydraulic linkage and other actuators, which can realize remote control and automatic operation. Two-way butterfly valve series products are long-life, energy-saving butterfly valves. Its structure adopts three-dimensional core design principle, the valve seat adopts a multi-layer structure compatible with hard and soft sealing, exquisite processing and advanced technology. This product is composed of main components such as valve body, butterfly plate, multi-level valve seat, valve stem and the transmission mechanism. Therefore, it is widely used in metallurgy, electric power, petroleum, chemical industry, air, gas, combustible gas, water supply and drainage and other corrosive media pipelines.
