Vacuum Valves & Components Butterfly Valves


Butterfly valve 

Butterfly valves are the most efficient and reliable sealing Isolation valve mechanism under high vacuum working conditions. A vacuum seal provided around the plate periphery in the main body of the valve ensures fail proof working of the valve. For efficient working of the valve it is advised to ensure that the sealing plates are facing atmosphere.

Butterfly Valves are of small in terms of thickness which ensures easy and faster passage for air and gases and are ideally suited for "In-line" isolation purpose. Though the butterfly valve is not intended to be used as an independent valve, it is widely used as a Baffle Valve in union with a chevron baffle at the top of a Diffusion Pump. These Butterfly Valves are offered in stainless steel SS-304 non-magnetic AISI quality high carbon steel chromium plated construction and they can be manually or pneumatically operated as per customer choice.
