REGULATION & PROTECTION
In order to optimise, protect and get the best possible performance from water networks (drinking, raw or waste water) and to ensure water availability for everyone, the networks must be regulated and protected against air, water hammer and foreign bodies. Regulating and protecting water networks also helps to reduce wastage due to losses in drinking water networks.
Many products can help you to do this:
- Pressure reducer
- Control valve
- Venting devices, air inlet damper, air venting device
- Surge tank, valve

Pipes regulation and protection
Pressure regulating valve
The pressure regulating valve has many functions.
Here are the applicable functions:
Downstream pressure reduction and stabilization
Upstream pressure maintenance
Flow restrictor (diaphragm or electric)
Reservoir's filling (Altimetric, by float, electric, etc...)
Electrical control and...
Spring pressure stabiliser
The pressure stabiliser allows the pressure in the water networks to be reduced.
Characteristics of the spring pressure stabiliser
Material :
Cast iron or brass
Coating :
Epoxy
Connection :
- Gas thread Ø 1/2 to 1
- Flange 40 to...
Anti-hammer relief valve
The anti-hammer relief valve is the equipment used to protect pipes against water hammer caused by the rapid closure of a shut-off device, a pump malfunction or the presence of air. It very quickly relieves the overpressure during a water hammer.
Characteristics of the anti-hammer relief...
Specific valve
Plunger valve
Device allowing to reduce the pressure or to regulate a flow rate with a very high precision and reliability over time.
Characteristics of Plunger valve
Body :
Cast iron
Coating :
Epoxy
DN :
100 to 2000 flanged (other DN on request)
PFA
10 to 160...
Air purge valve
The air purge valve is a system that allows the evacuation of air at a calibrated flow rate.
It allows to limit as much as possible the water hammer at the end of the filling of the pipes.
The air purge valve is installed in addition to an air inlet check valve.
Characteristics of the Air...
Single, double and triple function air relief valve
The single, double or triple function air relief valve allows:
The evacuation of air when filling the pipes
Air entry when emptying the pipes (or breakage)
Elimination of air pockets during operation
Characteristics of air relief valve
Body :
Cast iron, brass,...
Air inlet check valve
The air inlet check valve allows air to pass through the duct at a high flow rate during accidental vacuuming or draining.
It prevents damage to the pipes and/or the suction of the seals.
Characteristics of Air inlet check valve
Body:
Cast iron
Coating :
Epoxy
DN:
40 to...
Hydropneumatic anti-waterhammer
The hydropneumatic anti-waterhammer is used to absorb water hammer in transitory regimes.
Characteristics of Hydropneumatic anti-waterhammer
Water :
Clear or used
Coating :
Epoxy or stainless steel
Flow rate :
100 to 20,000 l depending on the length profile and...
