Bray: Metal Seated High Performance Butterfly Valves

Bray McCannalok Metal Seated High Performance Butterfly Valves. The Bray McCannalok Metal Seated Valve has been extensively performance tested in our state-of-the-art technology center and test laboratory. The Inconel® 718 metal seat has been contoured to provide control, strength and flexibility in high temperature applications. The Technology Groups design validation procedure includes cycle, Metal Seated Butterfly Valve - TechmaticA metal seated butterfly valve is a type of valve which can be used for isolating or regulating flow. The closing mechanism is the disc, which sits in the center of the valve body. The disc is connected to a handle or actuator via the shaft, which passes from the disc through the top of the valve body.Neles® buttefly valves - MetsoNeles® metal-seated butterfly valves are designed to truly optimize the efficiency of process operations by offering best-in-class valve capacity.

Herewith, sand and pebbles are embedded in the bore. The pipe system will never be completely free from impurities regardless of how thoroughly the pipe is flushed upon installation or repair.

When To Use Metal Seat Valves Vs. Soft Seat Ball Valves

Sep 29, 2016 · The primary advantage of metal seated valves over soft seated valves is their ability to withstand high temperatures and severe service conditions. Metal seats can endure severe flashing, hydraulic shock, abrasive process fluid, and high temperatures up to and exceeding 1,000° F. They are also ideal for high erosion or corrosion applications.High Performance Butterfly Valves - HuameiThe HUAMEI metal-to-metal seat high-performance butterfly valve are with metal seat for higher tensile strength, a 300 series stainless steel back-up ring in the seat cavity for axial seat support, and a disc that is case hardened by nitriding.Butterfly Valves - Henry Pratt CompanyButterfly Valves In 1901, a small group of industrialists started in their small metal fabricating shop and officially entered the valve industry in 1926 with the design/development of the first Pratt® rubber seated butterfly valve. Growth of our Company has also been closely associated with the increased use of rubber seat butterfly valves.

In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway.
