Omega Valves supplies parallel slide valves. The valves are used for isolating gas and liquid. They are particularly suitable for applications involving high pressure, and high temperature steam or water.

The gate valve with parallel slide can be manufactured for various applications and environments. Contact us now for more information.

The valves’ sealing action is generated by pressure, therefore a minimum differential pressure is required for satisfactory application of the product

Benefits of the parallel slide valve

  • No wedging is required - The valve uses system pressure and position to provide positive isolation tightness
  • The spring fitted between the disc provides the initial sealing factor. Line pressure is then used to maintain the sealing force
  • No torque required – Once the disc is in position no additional torque is required to maintain the seal
  • The valve is not subjected to dangerous stress levels during the opening/closing action
  • The valve requires a smaller operating force
  • The sliding action of the valve prevents debris accumulation and the premature damage of the components
  • The prevention of debris accumulation helps avoid seat failure, erosion, and leakage in the valve
  • The seal is placed on the outlet seat face only
  • The valve guarantees a smooth flow path between the seats

Any minor seat distortions can be accommodated for, as the discs have some freedom to align themselves between the seat faces

The parallel slide valve is suitable for the following locations and applications:

  • Power generation
  • Combined heat and power (CHP)
  • Chemical and petrochemical
  • Hospitals
  • Breweries
  • Coal
  • Gas and oil-fired power stations
  • Nuclear power stations
  • Turbine and process industries
  • Heating and ventilation
  • Large and small industrial complexes

Omega Valves fulfils the following standards

  • BE EN ISO 9001:2015
  • PED 2014/68/EU

The parallel slide isolation gate valve can be used in different environments. Special consideration is needed in extreme temperatures and pressure in regard to the material used.
