Connected pipes - Import export

DVK-HD® quick closure pipe couplings are ideal for a quick and safe mounting in pressure conveyors. The coupling is closed with two clamping levers, therefore a quick opening and closing of pipe connections is possible. The clamping lever can be locked in any desired position by a simple upward pull.

According to DIN2353 for pipe connections up to 60 bar

The oil drain device Type C2 is used for oil sampling or emptying the transformer tank. The device is welded into the transformer case. The device is designed for use together with connection pipe F DIN 42551 for draining the transformer case for regeneration purpose of the oil. The oil drain device Type C2 is deisgned in accordance with EN 50216-4:2002 type C2.

Our radiator valves DIN 42560 type A and type 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 mm). 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 type A NW 80 fulfil the tightness requirements and operating conditions in accordance with DIN 42560 as well as EN 50216-8.
