Non-return Valves

Caliber Valves offers Non-return Valves. They are used for practically all process fluids. They are of lift check type with bolted bonnet construction. They have flanged end connection for easy fitment and maintenance. The flange drilling can be as per ND 40/ ANSI B16.5 Class 150 as the case may be. These valves are available from 15 to 200 mm sizes. The body and cover plate are ASTM A 216 Grade WCB and the seat and disc are CS hard faced with 13% chrome steel for wear resistance. The spindle and other trims are of 13% chrome steel; and spiral wound gaskets are provided for positive sealing of the body cover plate joint. These non-return valves are essentially used for the safety of the equipment and the people handling them particularly in parallel operations. These valves make sure that there is no unintentional by-passing of the process media through the equipments and pipe lines when not required.
