Resistant to stress corrosion cracking and used on single, multi boiler or calorifier installations.
Fitting a Three-way Vent Cock ensures a constant connection from the boiler or calorifier to the atmosphere. Levers are available as an optional extra.
The use of specially designed 3-way vent cock on multi-boiler vented hot water heating systems, ensures that there is
always a direct connection from the boiler or calorifier to atmosphere, i.e. either to open vent or drain position,
enabling maintenance to be carried out on individual boilers.
