• Radiator (Butterfly) Valves are used as shut off valves for detachable radiators of Oil Cooled transformers.

Exclusive Features of our Buchholz Relay:

• Our flap has an Angular Flat edge, as compared to the conventional V shape which has only line contact with the valve body. Flat edge ensures almost Zero leakage
• Shell molded, Shot blasted and Fettled CI casting for Zero body Leakage and better finish
• Streamlined Flap design minimizes Frictional Resistance to fluid flow
• No Rubber lining, yet leak proof
• Valve is able to lock in "OPEN" and "SHUT" position by the cap
• Valve is equipped with a Butterfly Flap, which can be turned to Open and Close the valve
• The valve remains in Open position when the transformer is in "On-load" condition
• For Inspection and Repair of the radiator, the Butterfly flap is closed and the Radiator is detached from the transformer
