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 and Reliable Coating

With an epoxy-painted cast iron body, this plug valve is engineered for enhanced durability and corrosion resistance. The plug-type structure, coupled with quality sealing materials like PTFE and elastomer, ensures stable operation even in demanding environments, making it ideal for water, gas, and oil pipelines.

Versatile Applications and Flexible Sizing

Covering sizes from 15 mm to 100 mm, this valve accommodates a range of pipeline requirements. Its female threaded ends (BSP/NPT) enable easy integration into various systems, supporting both isolation and flow control procedures in municipal, industrial, or commercial pipelines.

Effortless Operation and Maintenance

Featuring a quarter-turn operation with stainless steel or carbon steel coated handles, the valve guarantees ease of use and quick shutoff. Designed for low maintenance and straightforward serviceability, it helps reduce downtime, improving overall system efficiency and reliability.

FAQ's of Screwed End Plug Valve:

Q: How do I install a Screwed End Plug Valve with female threaded connections?

A: To install a Screwed End Plug Valve, ensure proper alignment with your pipeline and apply thread sealant to the BSP or NPT female threaded ends. Carefully screw the valve onto the pipeline, avoiding over-tightening to prevent thread damage. Once positioned, verify that the quarter-turn handle operates smoothly before testing for leaks.

Q: What media types can this valve safely handle?

A: This plug valve is suitable for controlling flow in water, gas, and oil pipelines. The PTFE and elastomer sealing materials provide reliable sealing across a wide temperature range (-10C to 180C), ensuring compatibility and safe operation with these media types.

Q: When should I service or maintain this plug valve?

A: Thanks to its low maintenance design, regular inspection for wear or debris is recommended every few months, depending on usage intensity and media. If performance diminishes, the valve can be easily serviced; simply isolate the pipeline, remove the valve, and clean or replace internal components as needed.

Q: Where can this valve be used in industrial or commercial settings?

A: This valve is appropriate for pipeline shutoff, isolation, and flow control in industries such as water treatment, gas distribution, oil transfer, and general fluid handling systems. Its robust construction and reliable sealing make it suitable for both indoor and outdoor installations.

Q: What benefits does the bubble-tight Class VI leakage rating offer?

A: A Class VI (bubble-tight) leakage rating ensures virtually zero leakage when the valve is closed. This feature is particularly beneficial for critical applications, minimizing product loss, ensuring safety, and maintaining system integrity.

Q: How does the manual quarter-turn operation improve valve usage?

A: The quarter-turn handle enables fast and easy operation, allowing users to open or close the valve with minimal effort. This design enhances responsiveness in isolation or control scenarios, supporting quick shutoff during emergencies.
