Middleeast valve is the fastest growing Diaphragm Valve supplier in Oman. It is supplies industrial valves in Bahrain, Egypt, Iran, Iraq, Israel, Jordan, Kuwait, Lebanon, Oman. A diaphragm valve is a type of shut-off valve that is bi-directional. Structured differently than regular valves. A diaphragm, as the name implies, is the opening and closing element in a diaphragm valve. It is made of a soft/flexible material that is elastic, non-corrosive, and nonpermeable, such as rubber and plastic or elastomer. Diaphragm valves can be used for low pressure, low temperature, corrosive, and suspended materials applications. The benefits of a diaphragm valve are that they have a strong and positive sealing, corrosion-resistance, and low fluid resistance. These valves do not leak.

Advantages of diaphragm valve:

  • Diaphragm valves are particularly well-suited for the treatment of corrosive oils, fibrous slurries, toxic fluids, and other fluids that are free of contamination.
  • Throttling service can also be provided by diaphragm valves.
  • A diaphragm valve’s operating mechanism is not exposed to the media within the pipeline. Sticky or viscous fluids cannot enter the bonnet and disrupt the operating mechanism.
  • Many fluids that would clog, corrode, or gum up the working parts of most other types of valves will not clog, corrode, or gum up the working parts of a diaphragm valve.

Industries which use Diaphragm valve:

  • Water treatment plants.
  • Power plants.
  • Vacuum services.
  • Corrosion prone applications.
