Plug Valve Manufacturer in India

• 3-Way Plug Valve: Directs one inlet stream between two outlets or combines flow paths.

• Connection Lift Plug Valve: Lifts the plug before rotation to reduce sealing-surface friction.

• Eccentric Plug Valve: Uses an offset plug that moves away from the seat during opening.

• Jacketed Plug Valve: Uses a body jacket through which a heating or cooling medium can be circulated to help maintain the required process temperature.

• Lubricated Plug Valve: Uses an injected lubricant/sealant system between the plug and body to support sealing and reduce operating friction.

• Non-Lubricated Plug Valve: Uses a non-lubricated sealing arrangement, commonly incorporating a sleeve or other design-specific sealing system.

• Orbit Plug Valve: Combines lifting and rotary movement so the plug disengages before turning.

• Twin Seal Plug Valve: Uses two independent seals with a bleed arrangement between them.

Plug Valve Technical Specifications:

Plug Valve Selection for Process Conditions:

Selection should consider:

• Medium composition, solids content, and viscosity

• Operating pressure and temperature

• Required flow path and port configuration

• Allowable pressure drop

• Shut-off and leakage requirement

• Operating torque and actuator sizing

• Fire-safe or fugitive-emission requirements

• Body, plug, sleeve, seat, and seal materials

• Maintenance access and cycling frequency

Plug Valve Applications:

• Crude Oil and Gas Pipelines: Isolation of gathering, transmission and transfer lines.

• Refinery and Petrochemical Units: Shut-off and flow diversion in hydrocarbon process and transfer lines.

• Chemical and Fertilizer Plants: Isolation of compatible liquids and gases in process piping.

• Fuel Gas and Power Plant Lines: Shut-off of fuel-gas, fuel-oil and selected utility lines.

• Marine, Terminal and Offshore Systems: Isolation and flow switching in compatible loading, unloading and transfer piping.

Plug Valve Standards and Testing:

• API 599 – Metal plug valves within its applicable scope

• API 598 – Valve inspection and pressure testing

• ASME B16.34 – Pressure-temperature ratings, design, materials, testing and marking where applicable

• Fire-safe / fugitive-emission requirements – Applied according to the valve design and approved project specification

Inspection and testing may include material and dimensional checks, shell and closure testing, operating-torque verification, functional checks and required documentation.
