Key Features:

  • The dustproof ring combined with three layers of O-rings ensures reliable sealing and allows for online replacement.
  • Equipped with an aluminum bronze bearing embedded in the gate, providing excellent self-lubrication and high strength. The bearing can be replaced without replacing the entire gate after long-term use.
  • The gate is coated with rubber, offering anti-corrosion properties and strong sealing performance.
  • Advanced surface treatment with non-toxic epoxy resin powder coating enhances corrosion resistance and makes it suitable for potable water pipelines.
  • The body is designed without gate slots, ensuring a smooth flow channel that prevents debris buildup, making it ideal for sewage environments.
  • Offers reliable integral sealing, with zero leakage under 1.5 times the nominal pressure and low-pressure sealing at 0.02 MPa.
