Accessories for Oil Transformers
Pressure Safety Valves Type T-0.5
This type of Pressure Relief Valves features a one-piece brass housing. A stainless-steel spring, factory selected to a predetermined rating, is designed to release pressure build-up from within a sealed tank. A rubber o-ring seals the valve. There is a stainless steel pull ring attached to the valve shaft to allow for manual operation. These valves are designed to operate under environmental conditions encountered on outdoor applications. The exhaust port is protected by a “bug shield” cover which inhibits foreign matter from entering the valve body. The valve setting is stamped on the “bug shield” for fast and easy identification. These types are suitable for hermetically sealed transformers.

Operation
When gas pressure in the tank exceeds a specified limit, the valve automatically compresses the spring and drives the poppet valve, breaking the seal and venting potentially dangerous pressure. With the pressure reduced the valve automatically reseals itself to prevent entry of outside air.
