Plate heater body water union - has seat in T=piece for valve plug inserted through plate opening

摘要

The water union is particularly for a double-layer plate heater body, and comprises a T-piece whose side unions lead to openings in the plates, the other being connected to the heating system. The front plate(1) at least has a further opening(8) in the side furtherst from the T-piece(4), for insertion of a valve plug(10). This works against a seat(11) in the T-piece union(5). ADVANTAGE - No need for separate valve between circuit and heater body.
