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.

Reliable Sealing and Durability

With PTFE or metal seated options and graphite/PTFE packing, the Buttweld Plug Valve ensures secure, leak-free operation across a broad temperature range. The corrosion-resistant and epoxy coatings extend the valve's service life, making it a trusted solution for demanding industrial environments.

Versatile Applications and Easy Operation

Available in sizes 12" to 6", this plug valve is designed for manual, quarter-turn rotary operation, offering quick shutoff in pipeline, petrochemical, oil & gas, and chemical applications. ASME B16.10 face-to-face dimensions standardize installation and maintenance across varied systems.

Comprehensive Testing and Certification

Every valve undergoes rigorous testing in accordance with API 598, ensuring consistent performance under variable pressure conditions. Fire-safe design, blowout-proof stems, and compliance with leading standards make it suitable for critical installations, with material selection tailored to media and operating temperature.

FAQ's of Buttweld Plug Valve:

Q: How is the Buttweld Plug Valve used in industrial settings?

A: The Buttweld Plug Valve is commonly installed in pipeline systems within petrochemical, oil & gas, and chemical industries to regulate flow or shut off media such as oil, gas, water, and chemicals. Its quarter-turn operation enables fast, reliable switching.

Q: What materials are used for the body and sealing components of the valve?

A: Body materials include forged carbon steel, stainless steel, and alloy steel, specifically grades A105, F304, F316, F11, and F22. Sealing is achieved using PTFE or metal seats, with packing options of graphite or PTFE for leak prevention.

Q: When should I consider a fire-safe design for this valve?

A: A fire-safe design is recommended for installations where media pose fire risks or where industry regulations require additional safety. This feature is available on request and provides enhanced protection in hazardous environments.

Q: Where can the Buttweld Plug Valve be installed?

A: It is suitable for pipeline systems, petrochemical plants, refineries, oil & gas infrastructure, and chemical processing facilities, especially where buttweld end connections are standard.

Q: What is the process for valve testing and certification?

A: Each valve is tested according to API 598 standards to verify pressure integrity and performance. Face-to-face dimensions comply with ASME B16.10 to ensure compatibility in installation and operation.

Q: How does the blowout-proof stem benefit the application?

A: The blowout-proof stem design provides an added safety measure, preventing stem ejection even in the event of high-pressure scenarios or packing failure, thereby enhancing operational reliability.

Q: What are the main benefits of using this plug valve?

A: Key benefits include reliable shutoff, corrosion resistance, adaptable material options for diverse media and temperatures, and standards compliance for quality assurance, ensuring low maintenance and long-term operation in demanding environments.
