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 Performance for Multiple Applications

Designed for use with a variety of media-water, oil, gas, and steam-the flange end plug valve delivers reliable isolation and flow control. Its durable structure and flexible sealing options make it ideal for harsh environments in chemical plants, process industries, and water treatment facilities. With manual operation, users can easily adjust flow using lever or gear mechanism, ensuring straightforward and safe handling during plant operation.

Compliant with International Standards

Quality and safety are ensured through strict adherence to international standards, including API 598, EN 12266 for testing, ISO 5208 Rate A for leakage, and end connections matching ANSI, DIN, and JIS requirements. Face-to-face dimensions follow EN 558 Series 1 or ANSI B16.10, simplifying installation and retrofitting into existing systems. Buyers benefit from a proven solution trusted by distributors, manufacturers, and exporters nationwide.

Customizable Structure and Material Options

Clients can specify the body and cover materials-cast iron, mild steel, stainless steel, or alloy steel-matching unique operational or environmental needs. Flexible body coatings (epoxy or powder) enhance the valve's corrosion resistance. The plug valve's design also allows the selection of sealing type tailored to medium and application, supporting long-term reliability and maintenance ease.

FAQ's of Flange End Plug Valve:

Q: How do I select the correct pressure rating for a flange end plug valve?

A: To choose the appropriate pressure rating (PN10, PN16, Class 150, Class 300), consider your system's operating pressure and the medium being handled. Consult with your engineering team and reference site-specific standards to ensure compatibility with existing infrastructure.

Q: What materials are available for the body and cover of this plug valve?

A: Body and cover materials include cast iron, mild steel, stainless steel, and alloy steel. Custom materials can be requested to accommodate special chemical, temperature, or corrosion resistance needs for your application.

Q: When is it advisable to use a tapered plug-type valve in process industries?

A: Tapered plug-type valves are recommended for isolating and regulating flow in systems handling water, oil, gas, or steam-especially where bidirectional sealing and low leakage (ISO 5208 Rate A) are necessary for operational safety and efficiency.

Q: Where can these plug valves be installed in industrial plants?

A: These valves can be installed in pipelines requiring frequent shut-off or control, such as chemical dosing units, water treatment lines, and oil or gas process flow management areas. Their compatibility with standard flanged ends ensures easy integration.

Q: What is the process for operating this valve manually?

A: Manual operation is achieved via a quarter-turn lever or gear handle. Turn the handle through 90 degrees to open or close the valve, enabling fast and simple control of flow direction with minimal effort.

Q: What are the main benefits of using this valve for water treatment or chemical plants?

A: Key advantages include robust corrosion resistance, reliable sealing with several material choices, bidirectional flow, and straightforward manual operation. Its adherence to global testing and leakage standards ensures dependable service in demanding industrial environments.

Q: How is leakage class ISO 5208 Rate A beneficial for my application?

A: ISO 5208 Rate A certifies extremely low leakage, making these plug valves suitable for applications requiring strict fluid containment and enhanced operational safety, such as chemical processing and critical water supply systems.
