INTRODUTCTION

ADVANTAGES

  • Solid valve body, more stable

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

  • 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.

  • 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.

  • 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 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.

  • Provide material inspection report of main parts

    All bonde products can provide the material inspection report of the main parts.

FEATURES

Lugged Knife Gate Valve Feature:
1. Knife gate valve opening and closing part is the valve plate, the plate movement direction is perpendicular to the direction of the fluid. Knife gate valve can only be fully open and fully closed, can’t be used for adjusted and the throttle.
2.The valve plate has two sealing surfaces. The two sealing surfaces of the most common gate valve forming the wedge, the wedge angle various according to the valve parameters, usually is 50. Wedge knife gate valve plate can be made into a whole part , called the rigid gate plate; also be made to that can produce small quantities of deformation in order to improve its production process, to make up the sealing surface angle deviations arising during processing, this plate called resilient plate. The seal can only rely on media pressure to seal, which rely on media pressure to ram pressure to the sealing surface of the other side of the seat to ensure the seal, which is self-sealing.
