Non Slam Check Valves Collection

Specifically designed to handle water hammering caused by stored pressure in the valve, non-slam check valves (also called nozzle check valves) close without creating excess pressure spikes. The check valve’s unique pressure-eliminating feature makes it indispensable in oil and gas, refining, chemical processing, and power generation industries.

Honed by over 20 years of manufacturing experience, DomBor is the industry leader in affordable and reliable non-slam check valves in the market. Implementing streamlined processing and strict quality control standards, our non-slam check valves provide long-term service and peerless performance.

Highlights

  • None Slam type
  • Low Noise
  • Integral valve body without dew point
  • Venturi port design
  • Low Water Hammer

Main Features of the Product

  • Streamline flow passage, medium does not flow around, valve flow resistance is small, energy saving
  • The valve disc adopts anti erosion structure, so the fluid erosion to the sealing surface is small, which increases the service life of the valve
  • The valve disc is opened and closed automatically by medium force
  • Venturi port to minimize pressure drop
  • Short opening and closing stroke, automatic reset, no impact, in a small flow rate, the valve can be fully opened, short closing time.
  • The floating disc structure can automatically compensate the error caused by wear during installation and use, ensure the sealing surface to fit closely, and improve the sealing performance.
  • The unique structure enables the valve to be installed horizontally, vertically and at any angle without the limitation of installation position
