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.

Robust Construction & Design

Each API 6D Plug Valve features a sturdy expanding plug structure, engineered for double block and bleed functionality and blow-out proof stem safety. Manufactured in carbon steel, stainless steel, or custom materials, these valves offer excellent durability for critical pipeline applications, with corrosion protection available via fusion bonded epoxy coating.

Versatile Operation & End Connections

Designed for flexibility, these plug valves accommodate RF, RTJ, and BW end connections according to API 6D standards. Operators can select manual, electric, or pneumatic actuation to suit their process needs, and choose between reduced or full bore configurations for optimal flow control and isolation.

Stringent Testing & Reliable Sealing

Every valve is subjected to 100% hydrostatic and pneumatic testing for dependable performance at pressure ratings from Class 150 to 900. Sealing options include PTFE, Peek, and metal-to-metal, ensuring compatibility with diverse pipelines and secure shutoff for oil, gas, and water media.

FAQ's of API 6D Plug Valve:

Q: How is the API 6D Plug Valve tested before delivery?

A: Every API 6D Plug Valve undergoes comprehensive hydrostatic and pneumatic testing on 100% of production, ensuring leak-proof operation and compliance with international standards. This rigorous process certifies performance and reliability for demanding pipeline environments.

Q: What types of end connections are available for these plug valves?

A: API 6D Plug Valves are offered with Raised Face (RF), Ring-Type Joint (RTJ), and Butt Weld (BW) end connections, adhering to standard API 6D dimensions for seamless integration into various pipeline systems.

Q: When should double block and bleed plug valves be used in pipelines?

A: Double block and bleed plug valves are ideal for applications that require positive isolation, such as pipeline shutoff, maintenance, or sampling. Their design enables complete isolation and venting, enhancing operational safety and efficiency.

Q: Where can API 6D Plug Valves be installed?

A: These plug valves can be installed in oil, gas, and water pipelines for shutoff, isolation, or flow control. They are well-suited for both aboveground and buried service and are commonly used in distribution, export, and process systems throughout India and worldwide.

Q: What are the main benefits of an expanding plug valve structure?

A: The expanding plug structure provides tight shutoff, improved sealing under varying pressure conditions, and reduced wear on the sealing surfaces. This results in enhanced longevity and reliability in both full bore and reduced bore installations.

Q: How does the optional fusion bonded epoxy coating improve valve performance?

A: Fusion bonded epoxy coating offers superior corrosion protection, extending the service life of the plug valve, especially in harsh or corrosive environments. It safeguards internal and external surfaces against rust, moisture, and chemical exposure.
