Flanged butterfly valve is a type of flow control product that features simple switching and linear adjustment. Flanged butterfly valve has a simple structure, allowing it to achieve 90-degree rotation, enabling quickly opening and closing. Due to the low operating torque, it is effort-saving.

Features

Flanged butterfly valve has a novel structure with small overall size and light weight.
Double eccentricity for the valve disc makes quick switching, and labor-saving operation.
No sliding friction between the valve disc and sealing ring, designed with wear-resistant sealing surface, leading to long service life, reliable sealing and easy adjustment.

Applications

This flanged butterfly valve, as a type of flow control valve, is used to regulate the flow of gas, liquid and a variety of corrosive media and slurries, etc. in the petroleum, gas, chemical, and water treatment industries.

The butterfly valve is used in limited space as well as the fully open and fully closed positions for throttling or regulating flow.

Flanged butterfly valve is a user-friendly switch valve, installed in limited space for adjusting and throttling fluid flow.

Double flange butterfly valve is used for flow regulation and flow segmentation in water utilities, pipelines, irrigation and other areas. Due to the hydrodynamic design of the valve disc, it has a low water head loss, is 100% watertight and is gaskets-free.

Single flange valve is suitable for smaller pipework systems and general industrial applications, typically used in low pressure environments. Double flange valve is suitable for larger pipework systems and high pressure applications, better enduring the high pressure environments.

Butterfly valve, also known as flap valve, can be used to regulate, isolate and control fluid flow.

We produce flow control valves and accessories in accordance with various standards such as GB, ASTM, ASNI, BS, DIN, JIS, etc.!
