Stainless steel pneumatic butterfly valve structure features: the use of stainless steel as the main material is a circular disc rotation with the valve citrus hoist, pneumatic valves to enable action to achieve the main job of the cut-off valve can also be designed to be capable of regulating or, paragraph valve and adjust the function, the current use of pneumatic butterfly valve on the low-pressure medium and large diameter pipes is very wide.
Stainless steel pneumatic butterfly valve of the major advantages of simple structure, small size, light weight, low cost, This feature is particularly pneumatic butterfly valve installed in the high-altitude underground passage after two five-way solenoid valve controls easy to operate, regulate the flow of media. Fluid resistance is small, large diameter pneumatic butterfly valve fully open when the effective flow area, close quickly and effort, the 90 angle of rotation of the disc pull to complete the opening and closing force due to the shaft on both sides of the disc plate hand media close to equal. torque in the opposite direction, thus opening and closing torque is small, low pressure to achieve a good seal butterfly valve sealing material nitrile rubber, fluorine rubber consumption of rubber, PTFE lined therefore, good sealing performance, including sealing butterfly valve weight advantages of hard and soft cascading sheet metal to metal seal and the flexible seal with excellent sealing performance at low temperatures. |
