Electric Flange Soft Sealing Gate Valve

1.Structure design, valve body: mostly select and use nodular cast iron or carbon steel materials, nodular cast iron valve body has excellent strength and anti shock performance, able to withstand a certain degree external force shock; carbon steel valve body has excellent withstand pressure performance, applicable to middle and high pressure working status. The internal runner design is straight in type, and surface smooth, ultra big degree reduce the resistance when medium flowing, reduce the energy consumption and guarantee the fluid smoothly pass through. Gate plate: make the metal as base, surface fitting best quality rubber sealing layer, such as the nitrile rubber, EPDM and other best quality rubber and others. The metal base provide stable structure support, the rubber sealing layer able to tightly fitting the valve based on high elastic and flexibility, realize dual ways sealing, able to validly prevent medium leakage. Valve rod: select and use the best quality stainless stee…
