Our transformer radiator valves DIN 42560 type A and A OR are designed to be welded onto the transformer wall or on connection pipes. The radiator will be flanged on the four M16 holes (PCD=160). The housing of the radiator valve is made of forged steel S355J2G3 and thus not subject to any leakage as it may occur with casted housing.
Due to the metal sealed clap a low leakage is permitted while the soft-sealed radiator valve is absolutely oil- and vacuum-tight. Both types are absolutely tight in operation condition to the outside. Our welding neck radiator valves DIN 42560 A NW 80 fulfil the tightness requirements and operating conditions in accordance with DIN 42560 as well as EN 50216-8.
