Industrial valves are mechanical devices used to regulate, control, or direct the flow of liquids, gases, or slurries within a piping system. They play a critical role in industries such as oil & gas, power, water treatment, marine, and chemical processing.
1. Types of Industrial Valves
• Gate Valve
Used for on/off service with minimal pressure drop. Suitable for full flow applications.
• Globe Valve
Designed for throttling and flow control with better sealing capability.
• Ball Valve
Quarter-turn valve offering quick shut-off and low maintenance. Available in 1-piece, 2-piece, and 3-piece designs.
• Butterfly Valve
Lightweight and cost-effective valve for large diameter pipelines.
• Check Valve (NRV)
Prevents backflow in pipelines. Types include swing check and lift check.
• Plug Valve
Simple quarter-turn valve used for isolation in various industries.
