Lug Butterfly Valve PTFE Seated With Worm Gear

Product Description

Functional Role and Target Users

This lug-type butterfly valve is designed for controlling and regulating fluid flow in systems managing corrosive substances such as acids, alkalis, and organic solvents. It targets industries requiring chemical resistance and flow precision, including chemical processing and related sectors. The valve’s compact size suits installations with limited space and scenarios needing reliable sealing performance.

Technical Features and Specifications

Equipped with a PTFE lining for chemical resistance and a worm gear mechanism for smooth 90° rotational control, this valve ensures minimal leakage and ease of operation. It conforms to standards such as BS EN593 and API609, with flange compatibility following ASME B16.47 and DIN specifications. The body uses carbon steel with PTFE lining, and the operating temperature range spans -30°C to 180°C, supporting pressures up to PN1.6 MPa depending on the model.

Application Compatibility and Value

This valve replaces various valve types including gate and globe valves, providing a versatile option for pipelines requiring corrosion resistance and precise flow control. Options for pneumatic or electric actuators enable remote operation, making it suitable for automated systems. It fits well in industrial environments that manage corrosive media and demand consistent sealing under varying pressures and temperatures.

Product Advantages

Procurement-Relevant Design and Compliance

The valve’s design complies with multiple international standards, supporting cross-regional sourcing and installation requirements. The use of certified materials such as PTFE-lined carbon steel contributes to predictable performance in corrosive environments. Its lug-type configuration facilitates straightforward flange connections, beneficial for maintenance and replacement considerations within procurement processes.

Operational Fit and Supply Chain Value

Available options for pneumatic or electric actuators allow adaptation to different control systems, supporting OEM or customized applications. The valve’s compact and lightweight construction reduces handling and shipping complexity. Quality testing aligned with EN12266-1 and API598 ensures product consistency that distributors and buyers can verify before bulk orders or project deployment.
