Pressure balance lubricated plug valves are metal seated valves providing a tight shut off ( 0 leakage ) sealing, valves shall be regularly lubricated along with their operation by injection of suitable grease. Due to no body cavity and as well as a simple & tough design, they are highly recommended for any critical Full P operation and for handling any media with an high % of solids contents, further more they provide an excellent resistance to abrasion, they are free from routine maintenance, providing a long service life.

Built for Demanding Industrial Applications

The Class 300 Plug Valve is trusted by distributors, exporters, and manufacturers for industrial piping systems in oil & gas, petrochemical plants, and refineries. With a durable forged carbon steel body and premium epoxy or anti-corrosive coatings, it ensures long-lasting performance even under harsh operating conditions and wide temperature ranges of -29C to 425C.

Enhanced Performance and Leak-Proof Integrity

Precision-designed to ASME and API standards, this plug valve guarantees reliable flow regulation and superior sealing through PTFE or metal-to-metal seats. Its full port options minimize pressure drops, while robust flanged connections ensure secure installation and easy integration into existing piping networks.

FAQs of Class 300 Plug Valve:

Q: How does the quarter turn operation benefit users of the Class 300 Plug Valve?

A: The quarter turn operation enables quick and effortless opening or closing of the valve, making it highly suitable for manual control in pipelines requiring reliable shut-off or flow adjustment with minimal effort.

Q: What are the advantages of the blowout-proof stem design and epoxy coating?

A: The blowout-proof stem provides enhanced safety by preventing stem ejection under pressure, while the epoxy or anti-corrosive coating extends the valves lifespan by resisting corrosion and wear in aggressive environments.

Q: When should I select full port versus regular port for this plug valve?

A: Full port is ideal for applications where minimal flow restriction is needed, as it allows maximum media passage. Regular port is suitable for most general-purpose uses where slight pressure drops are acceptable.

Q: Where is the Class 300 Plug Valve typically installed?

A: This valve finds widespread application in oil & gas pipelines, petrochemical processing facilities, refineries, and various industrial piping systems requiring dependable shut-off and regulation.

Q: What is the process for routine maintenance of this valve?

A: Routine maintenance involves checking the seal integrity, lubricating moving parts, and inspecting the epoxy or anti-corrosive coating. The non-rising stem and simple construction make service and repairs quick and straightforward.

Q: How does the valve ensure effective sealing for different media?

A: Depending on the application, the valve can be supplied with either PTFE (for chemical compatibility and low friction) or metal-to-metal seats (for high-temperature or abrasive service), guaranteeing optimal sealing and performance.
