Parallel slide valve for isolating liquid and gas

Parallel slide isolating gate valve [Parallel slide valve]

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.
