Butterfly Valve by manual Operator with Stainless Steel Material

Butterfly Valve by manual Operator with Stainless Steel Material


as one of the most durable of all resilient-seated butterfly valves in the industry, this valve excels in a wide variety of applications. Cast in both wafer and tapped-lug patterns in a wide variety of material choices, butterfly valve features a one-piece body for reduced weight and increased strength. The unique stem-hole design in the disc ensures a dry stem journal, and the hard-backed seat allows ease of installation, reliable operation, and is field-replaceable without special tools. The butterfly valve is available in sizes 2" through 36" (50 mm through 900 mm). Engineered for long-term, maintenance-free performance, the butterfly valve is commonly selected for a variety of applications spanning a wide range of industries.

Design Details: A butterfly valve is a valve which can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. Operation is similar to that of a ball valve (quarter turn) which allows for quick shut off. Butterfly valves are generally favoured because they are lower in cost to other valve designs as well as being lighter in weight, meaning less support is required. The disc is positioned in the centre of the pipe, passing through the disc is a rod connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, therefore a pressure drop is always induced in the flow, regardless of valve position. The valve may also be opened incrementally to throttle flow.
