zhejiang soft sealing valve production pneumatic butterfly valve beautiful shape, the valve body, valve plate and valve spindle is concentric structure, including rubber and epdm seal valve body can be in the seat design, not only low cost, and convenient maintenance, and ZMA pneumatic actuator systems. Widely used in food, environmental protection, light industry, petroleum, paper making, chemical industry, electric power industries such as industrial automation systems.

these days meet a customer order in pneumatic butterfly valve to the clamp, the use of medium temperature errors, caused by valve seal configuration is wrong, we often emphasize inquiry with a customer must provide the accurate using parameter, but some customers are middleman, don't understand the site usage, often ignored when inquiry many details, such as the valve to the scene found that selection is wrong, and want a replacement, the Industrial Valves is made according to the working condition of each user's standard, the exchange will generate depreciation cost, freight, packing costs, etc.

so soft sealing pneumatic butterfly valve is according to which parameters selection? Today and all simple share several important parameters.

1。 Soft sealing material: nitrile butadiene rubber ( Oil resistant) , epdm ( Ageing resistance) , wear-resisting rubber ( Wear resistant) And these three material heat resistance & le; 80℃； Ptfe sealing ( High temperature resistance, corrosion resistance) Heat-resistant & le; 150℃。

2。 The valve body material: cast iron, cast steel, 304316316 L

3. The valve material: iron plate, galvanized sheet, nylon sheet, 304316316 L

4. Working medium: water, oil, gas, fine powder, etc.

5. Using pressure: 1. 0 - 1. 6 mpa as domestic high-end valve manufacturer, has been in response to national policy and called for, committed to research and development, manufacture, electric butterfly valve, stainless steel ball valve, discharge valve, electric gate valves, stainless steel gate, stainless steel valve, stainless steel check valve, high pressure gate valves high-quality let customer trust of good valves, valve to keep the traditional valve product sales profits to escort for the innovation research.
