Principle Features

INTRODUCTION
Leader Horizontal Lift Check valves are designed with high sensitivity to pressure so that the valve closes immediately before significant fluid starts flowing backward. Fluid reversing backward causes damage to equipment like boilers or pumps. The valve is activated by the flowing material in the pipeline. The pressure of the fluid passing through the system opens the valve disc, while any reversal of flow will lose the valve disc. Closure is accomplished by the weight of the check mechanism, by back pressure. Disc guides enhance the proper alignment of the disc and seat configuration when the disc closes. Entirely automatic in action, depending upon differential pressure and velocity of flow within the line to perform their functions of opening and closing.

  • Design Std.: DIN EN 12334.
  • Bolted Cover, Piston type Disc design.
  • Metal to Metal seating.
  • Stainless Steel Body & Disc rings.
  • Rigid & Sturdy design.
  • Long service life as wear is minimal which makes it highly reliable.
  • Valve is mechanically automatic and thus it does not need an actuator or valve operator.
  • Suitable for only horizontal installation.
  • The valve must be installed in the direction of the flow arrow.
  • Flanged ends as per DIN EN 2533 PN-16 R.F.
  • Valves are available with IBR Certification up to size 200mm.
  • Widely applied for low-pressure and ambient-temperature utility services such as water supply, power plants, gas supply, district heating piping, irrigation projects, air conditioning systems, as well as food processing industry, chemical and petrochemical industry, Boiler industry, pharmaceutical, and powder industry to prevent the backflow.

END CONNECTION

  • Flanged ends as per DIN EN 2533 PN-16 R.F.
  • Flange drilling as per other standards also available upon request.
