pressure reducing valve difinition
2012-05-11
This valve reduces the pressure of the water
that goes through it, and is used to obtaining a regulated and constant value at
its outlet.
It is installed at the water mains (for a bungalow as for a flat). It protects the whole installation from problems due to excess pressure : noises in the pipes, water hammer, splashes, premature wear of household electrical appliances and taps.
The pressure REDUCING VALVES are completely automatic.
Practical rule : the pressure reducing valve
is generally chosen according to the diameter of the installed pipe, provided,
of course, that the latter is of the right size.
The choice of pipe diameters must follow the
rules of the trade and must conform to the standards in force.
Refer to the flow rate curves of each
pressure REDUCING VALVE, given in the technical documents.
