Product Description

Lever Operated Concentric Ductile Iron Body Fully Lug Type Butterfly Valve 

Product Description

The lever-operated concentric ductile iron body fully lug type butterfly valve is designed to regulate fluid passages by opening and closing the disc through reciprocating gyrations at approximately 90 degrees.

This valve offers a range of benefits, including a simple structure, compact size, lightweight design, low material consumption, small installation footprint, low driving moment, easy operation, and fast response.

Additionally, it boasts excellent flow regulation capabilities and sealing characteristics.

Over the past few decades, butterfly valves have experienced significant growth and have become one of the most popular valve types worldwide.

Developed countries such as America, Japan, Germany, France, and Italy have widely adopted butterfly valves, leading to an expansion in both variety and quantity.

Furthermore, these valves are continuously evolving to meet the demands of high-temperature, high-pressure, large-caliber applications, while also offering enhanced sealing, extended lifespan, superior regulation capabilities, and multifunctionality.

To cater to industrial applications that involve extreme temperatures, corrosive environments, and prolonged service life, our lever-operated concentric ductile iron body fully lug type butterfly valve is the ideal choice.

With its robust construction and advanced features, this valve ensures reliable performance and longevity.

Advantages:

Butterfly valves are easy and fast to open.

Butterfly valves are relatively inexpensive to build.

Butterfly valves have less space requirements.

Butterfly Valves are generally associated with reduced maintenance.
