INTRODUTCTION

VENTAJAS

  • Bundor patented valve products

    Valve side flange conform to a variety of domestic and foreign standards of multiple pressures, easy connection, wide adaptability.

  • Strong pressure bearing capacity of valve body wall

    Valve body wall thickness to meet the requirements of GB 26640, thick thickness, pressure strength is guaranteed.

  • 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.

  • 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.
