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.

  • The seat has a long service life

    Valve seat is made of imported rubber, with 50% rubber content, long service life and more than 10000 opening and closing times.

  • Solid valve body, more stable

    Valve body is solid body, same caliber weight is heavier than other manufacturers.

  • 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.

  • Valve body spray brand epoxy resin plastic powder

    Valve body spray using brand aksu epoxy resin plastic powder, can deposit thicker thickness, melt curing adhesion is stronger. 

  • The sign has a beautiful appearance and strong connection

    Laser marking, clear writing, long life.Use stainless steel rivet to fix, the appearance is more beautiful, the connection is more firm.

FEATURES

1. The fluid resistance is small, and the effective circulation area is large when the pneumatic disc valve is fully open.
2. The opening and closing are quick and easy, and the disc is rotated 90 angles to complete the opening and closing.
3. Due to the proximity of the dielectric force of the disc plate on both sides of the rotating shaft, the torque direction is the opposite, so the opening torque is smaller.
4.can achieve good sealing, low disc valve sealing materials have nitrile butadiene rubber, fluorine rubber, rubber, four fluorine lining so sealed performance is good, the butterfly valve is not only in the oil, gas, chemical industry, water treatment and other general industrial used widely, but also applied to the cooling water system of thermal power plants.
