Lug type hard seal butterfly valve

Product Overview

The Lug Type Hard Seal Butterfly Valve is a rugged, high performance valve designed for demanding industrial applications. Its lugged connection allows for safe and easy installation between two flanges, thus permitting maintenance to be performed on one side of the pipeline without affecting the other side. The hard seal design ensures excellent sealing performance even under extreme conditions and is suitable for high temperature, high pressure and abrasive media.

The valves are widely used in petrochemical, power generation, metallurgy and water treatment industries that require reliable and durable flow control.

Product Characteristics

Lug design: easy connection with threaded inserts, no interference with neighboring pipe sections during valve installation or removal.
Ensures secure installation even in high vibration environments.

Hard seal structure: metal-to-metal seal design with excellent wear resistance, resistance to thermal cycling and deformation.
Withstands temperatures up to 450°C and pressures up to PN40.

High-performance valve flap and seat materials: Flap and seat materials include stainless steel, stellite, or special alloys for increased durability and corrosion resistance.

Low Torque Operation: Precision engineering ensures smooth operation with minimal torque, thus reducing the energy requirements of the actuator.

Ease of Maintenance: Replaceable valve seats and modular construction allow for easy maintenance and extended service life.

Wide range of compatibility: A wide range of sizes and material options are available to suit different media and working conditions.

Product Advantages

Enhanced durability: The hard seal design ensures long service life even in harsh environments containing abrasive or corrosive media.

High reliability: zero leakage in both directions (bi-directional sealing).

Wide temperature and pressure ranges: efficient operation even under extreme conditions, suitable for a wide range of industrial applications.

Cost-effective: Low maintenance requirements and durable construction reduce overall life cycle costs.

Flexible Installation: The lug design allows for quick and flexible installation in flanged pipes.
