Adaptor fitting for radiator valves

摘要

The fitting includes a shut-off valve (14,15) in each channel (3,4). The two shut-off valves can be operated independently of each other and of the regulating or shut-off valve (9) in the associated connecting channel. The closure bodies (16,19) are connected together by a preferably integral valve spindle (2). The valve spring can have a threaded bore on the operating side (23) which can be closed by an emptying spindle. The valve spindle can also have a through-bore connected to the threaded bore and closable by a projection of the emptying spindle.
