INTRODUTCTION

ADVANTAGES

  • Spherification rate 3, suitable for higher working pressure

    Valve body is qt450-10 material, mechanical properties are stronger, the same thickness of tensile strength is twice the iron body.

  • Valve shaft support is strong, axial sealing is reliable

    Valve shaft and valve body with 4 oil-free bearings, 3 O sealing, valve shaft support more powerful, more reliable axial sealing.

  • Ultrasonic cleaning before packaging

    Eliminate impurities in the valve body, ensure the cleanliness of the valve and prevent the valve itself to pipe water pollution.

  • The position of signboard is humanized

    The position of the signboard is humanized and set on both sides of the valve body for users to view after installation.

  • Heat-shrinkable film for independent packaging

    PE thermal shrinkable film is used to package the valve independently, and built-in desiccant, to isolate air dust, avoid damp pollution valve.

  • Disc pin has high strength and abrasion resistance

    The pin adopts tempering treatment, high strength, abrasion resistance, safe and reliable connection.
