Control Valve

Salient Feature


This type of Valve with its classic globe body shape, which reflects its Name, uses the variable area generated between the plug and seat to Control fluid flow. It is very versatile offering reduced trim options as well As a variety of special trims for severe high pressure drop applications. This style of valve is easily adapted for use on cryogenic temperatures And for high temperature duties.

This valve is preferred for tight shut – Off, positioning accuracy, high range ability and simplified maintenance, Satisfy the majority of control valve applications throughout the process And power industries in control of Air, Steam, Water, Gas, Chemicals, Paper mills, Sugar Industries, Power plant, Oil refinery Industries, Rice mills industries, Etc.

  • High flow capacity and rangeability.
  • Large variety of Trim design.
  • Top entry for ease of inspection and maintenance.
  • Tight closing for reliable control even when changes in pressure / temperature are sudden and extreme.
  • Bolts located outside of the piping stress area to eliminate gasket crush problems.
  • Wide selection of actuators to meet most system requirement.
  • Rigorously proven on-site performance
