Valve castings

Different types of Industrial Valves include:


Gate Valves.

Gate valves are used to either halt or start the flow of water. Functioning of gate valves includes the lifting of a circular of the rectangular gate out of the fluid path. When gate valves are open, there will be nothing to obstruct the flow as the pipeline diameter and gate have the same opening. The valve size can be determined with this bore diameter.

 Globe Valves

Globe valves are composed of a baffle that splits the inside of the pipe, which is typically parallel to the pipe's length. They are named for their spherical body shape with the two halves of the body being separated by an internal baffle. It consists of a movable disk-type element and a stationary ring seat in a generally spherical body.

 Ball Valves

Ball valves work by allowing the hole to be open, blocked, or open partially to regulate the flow of gas/liquid. Ball valves are the ideal choice for using with gases as they are able to offer better sealing. They are very versatile as they support pressures up to 700 bars and temperatures up to 200°C and sizes typically range from 0.5 cm to 30 cm. They are easy to operate and repair as they contain a simple structure.

 Butterfly Valves

Butterfly Valves are designed to regulate flow, but with limited control capability. Butterfly valves are easily operated by rotating a handle 90 degrees. It consists of a metal disc in the body of the valve which is positioned perpendicular to the flow in the closed position. Regulation of liquid flow can be allowed through intermediate rotations. Butterfly valves are configured to operate electronically, manually or pneumatically.

 Check Valves

Check Valves are also known as Non Return Valve (NRV). They allow liquid to flow in one direction only and prevents back flow of media in the reverse direction. The purpose of check valves is to prevent process flow from reversing in the system which could damage equipment or upset the process.As they have a simpler design, they can operate without human interaction and automation. They rely on the flow velocity of the fluid to open and close. The higher the flow rate, the more open the valve will be until it reaches it maximum, full open position.


  • Gate valves are used for on-off appplicaitons  and in high temperature and pressure conditions.
  • Global valves are used primarily for throttling purposes
  •  Ball Valves are used for flow ,pressure control and shut off for corrosive fluids, slurries, normal liquid and gases in oil and natural gas industry.
  • Butterfly valves are used for corrosive liquids at low temp and pressure in pharmaceutical, chemical, and food processing services.
  • Check Valves used to to prevent backflow and maintain pressure, protecting pumps in liquid applications or compressors in gas systems
