Gate Valves

Gate valves function through lifting or lowering of a gate to start or stop flow.

Applications of gate valves are as follows:

•       Oil pipelines
•       Water distribution
•       Steam systems
•       Isolation services

They are built to provide complete open or complete shut positions and not for throttling.

Globe Valves

Globe valves are made to regulate flow with accuracy.

Globe valves are used in:

•       Chemical industries

These provide better throttling performance than gate valves.

Check Valves

Check valves allow flow in one direction and prevent flow in reverse direction.

Their common uses include:

•       Pump discharge lines
•       Water supply systems
•       Chemical transfer systems
•       Compressors

Selecting a proper check valve will protect equipment from backflow.

Plug Valves

Plug valves have a cylindrical or tapered plug for flow control.

Their common applications include:

• Chemical Processing
• Fuel Systems
• Slurry Applications
• Corrosive Media

Key Factors to Consider When Selecting an Industrial Valve

Selection of the right valve requires consideration of a number of operating parameters.

Type of Fluid

It is necessary to understand the nature of the fluid passing through the pipe:

• Water
• Steam
• Oil
• Gas

Sealing requirements depend on the nature of the fluid.

Operating Pressure

Each valve has a rated operating pressure.

The valve to be chosen must have a pressure rating higher than that of the system being operated.

Operating Temperature

Temperature greatly influences the operation of valves.

In high-temperature applications special materials and sealers are needed to handle thermal expansion and continuous heat resistance.

Valve Size

Valve size must coincide with the system and flow rate capacity.

Large or small valves decrease efficiency and cause excessive wear.

Corrosion Resistance

If there is corrosive medium, the valve must be corrosion resistant.

Corrosion resistant valves require less maintenance and have extended lifespan.

Maintenance Requirements

To choose valves which are easy to maintain and inspect.

Low maintenance valves decrease lifecycle costs and production downtime.

How Different Industries Select Industrial Valves

All industries have different requirements for their operations.

Oil & Gas

The valves used in the oil and gas industry should be able to handle:

•       High pressure
•       High temperature
•       Aggressive fluids
•       Concentration

Commonly used valves are ball valves, gate valves, and control valves.

Chemical Processing

For valves used in the chemical industry, corrosion resistance and durability to aggressive materials are important.

Material compatibility comes first.

Power Generation

Valves that can deal with:

•       Concentration of high-pressure steam
•       High temperature
