PRODUCT DESCRIPTION
The RADIATOR VALVE series has been designed to offer an easy and reliable solution for disconnecting the transformer radiator, featuring a typical square DIN flange (3"/80 mm opening), on transformer tank walls and cooling banks.
The SW series features metal-to-metal sealing and has a special thin butterfly blade that allows for a low oil-leakage rate in the closed position. It is available with the "wafer" design (mounting between flanges) and "welding neck" design—flanges either with OR6400 seats or flat without seats.
The TW series features total sealing with an O-ring (zero leakage) and has a special throttle with an O-ring. It is available only with the "wafer" design and flanges with OR6400 seats.
Both the SW and TW 80 series bodies are made of forged mild steel (no cast iron, so no porosity and no sweating), zinc-plated and with an epoxy paint finish suitable for standard indoor and outdoor applications. The shaft comes in carbon steel or stainless steel. The drive and gland are made of nickel-plated brass and have a padlocking function. An aluminum label indicates the open/closed position in 4 languages.
The radiator valve series features a special finish by request for extreme environmental conditions (i.e. very polluted areas, very cold/hot or very low temperature, corrosive/aggressive environments, etc.). The TW80 series is also available with an AISI 316-L stainless steel body for offshore applications.
