Our radiator valves DIN 42560 type B and type B OR for transformers are designed to be mounted between two flanges or between tank wall flange and radiator flange. The flange is made of forged steel S355J2G3 and thus not subject to any leakage. Flange thickness is h=40 mm with recessed body. Our radiator valves DIN 42560 B and B OR NW 80 fulfill the tightness requirements and operating conditions in accordance with DIN 42560 as well as EN 50216-8. Due to the metal sealed clap a low leakage is permitted while the soft-sealed radiator valve is absolutely oil and vacuum-tight (zero-leakage). Both variations are absolutely tight in operation condition to the outside of the transformer.
