About Lubricated Plug Valve

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.

Superior Sealing and Leakage Protection

The valve achieves a Class VI bubble-tight seal through advanced sealing options such as PTFE, elastomer, and metal-to-metal, making it reliable for water, oil, and gas media. This minimizes emissions and leakage, vital for safety and environmental compliance in critical process industries.

Compliance with Global Standards

Designed and tested according to API 599 (design) and API 598 (testing), as well as ASME B16.10 for face-to-face dimensions, this lubricated plug valve meets stringent international requirements. End standards ANSI, DIN, BS, and JIS support seamless integration into global infrastructure projects.

Versatile Operation and Installation

Engineered for manual or gear-operated power modes, this valve is suitable for both small and large diameter pipelines. The choice of flanged, screwed, or welded connections, combined with a range of valve sizes (DN50 to DN300), allows fast, secure installation and adaptability in complex plant layouts.

FAQ's of Lubricated Plug Valve:

Q: How is the lubricated plug valve operated and in which scenarios is manual or gear operation preferred?

A: This plug valve is operated via a quarter-turn rotary mechanism, available in both manual and gear-operated modes. Manual operation suits smaller valve sizes or less frequent adjustments, while gear operation is recommended for larger valves (such as DN150-DN300) or where torque requirements are higher, such as in oil and gas or power plant pipelines.

Q: What standards does the lubricated plug valve comply with and how does this benefit users?

A: The valve adheres to end standards like ANSI, DIN, BS, and JIS, and is designed to API 599, tested per API 598, and follows ASME B16.10 face-to-face dimensions. Compliance ensures high product quality, compatibility with global piping systems, and confidence in safety and performance.

Q: Where can this lubricated plug valve be installed and what is the typical range of applications?

A: These valves can be installed in oil and gas facilities, petrochemical plants, and power generation units. They are suitable for controlling water, oil, or gas flow within a temperature range of -20C to 200C, providing reliable service in both upstream and downstream processes.

Q: What materials and surface finishes are available for the valve, and why are they important?

A: Available in carbon steel, stainless steel, and alloy steel, with surface finishes like epoxy coating or paint, these options enhance corrosion resistance and allow the valve to withstand harsh media and environments typical of industrial applications.

Q: How does the plug type and body design influence valve performance?

A: The choice between cylindrical and tapered plugs allows for tailored sealing efficiency and flow characteristics, while the bolted cover body type enables easier maintenance and access, contributing to reduced downtime and improved operational reliability.
