Valvelink are dedicated to providing a wide range of heavy-duty valves for industrial applications including iron wafer butterfly check valves. These valves are particularly used for preventing the back-going of medium in pipelines. The pressure of the medium in pipes will operate the opening and closing functions of the valves automatically. In the event of back-going medium in the pipelines, the valve disc on the iron wafer butterfly check valves will automatically close to prevent accidents.

Features of iron wafer butterfly check valves include:

  • Tight seal to prevent any leakage under pressure
  • Safe and reliable operation
  • High interference resistance
  • Robust cast iron material for longevity
Specifications of iron wafer butterfly check valves include:
  • DN nominal diameter: 40 ~ 600mm
  • Nominal pressure: 1.0 - 1.6 PN
  • Sealing testing pressure:  1.1 - 1.76 MPa
  • Body testing pressure: 1.5 - 2.4 MPa
  • Working temperature: -15ºC - +80ºC
  • Suitable mediums: Sea water, fresh water, sewage, air, steam, food, medicine oils, acids etc.
Iron wafer butterfly check valves are robustly designed to provide a solid performance particularly in preventing unwanted back-going medium to avoid accidents making them ideal solutions as safety valves.
