Applications

The Fig 175 Three Way Cock has been designed for use on vented hot water systems, to ensure there is a permanent connection from the boiler or calorifier to atomosphere. Fitting a Fig 175 allows the use of a single common vent pipe, and permits continued operation of the system whilst maintenance is carried out on an individual unit.

Construction

The Fig 175 is of gunmetal construction, with all wetted parts manufactured from dezincification resistant materials. A stop incorporated in the gland locates with the plug to ensure that the boiler connection is always open to atmosphere, either via the vent or the drain. End connections have female threads to BS 21, and the DN65 size is also available with flanged boiler and vent connections. Fig 176 malleable iron operating keys, designed to fit the plug squares, can be supplied if required.

Features

  • BOILER CONNECTION PERMANENTLY OPEN
  • NO WATER LOSS ON CHANGEOVER
