When the downstreampressure is too low, nopressure is acting on themembrane and the pilotG opens, pressure in theupper chamber is relea-sed and the valve Aopens reproducing themovement of the pilot.

The pilot G is set at agiven downstream pressu-re to be maintained. If thepressure downstream ishigher than the settingpressure, the valve Aworks in closing phaseuntil the setting pressure isreached. When the downstreampressure is below the set-ting pressure the valveworks in opening phaseuntil the setting pressure isreached downstream.The upstream pressuremust be fairly higher thanthe setting pressure.

DISCHARGE VALVE

Installed on a bypass of the zoneto be protected, this valve openswhen the preset pressure is rea-ched. It stays open for as long asthe overpressure lasts and eva-cuates the surplus water into atank, a drain or to a low pressurezone.Equipped with non-return valves (checkvalves) it closes in the event of a returnof water in the discharge network.(C 401 C).

Setting ranges :


13.78 to 27.57 bar

Eliminates pressure fluctuationsdue to start up, shut down or fai-lure of a pump, or in case ofpower failure.This valve, always installed on a bypass,drains a certain volume of water towaste or back to the feeding reservoir.This may happen in two phases :a) the water hammer action creates inanticipation a drop in pressure which willrelease the corresponding volume ofwater.b) if effect is not sufficient, the valve willreact in real time to the following over-pressure.

• C 502 is similar to C 501 but the antici-pated surge protection pilot is replacedby a solenoïd valve.• C 503 is a combination of both C 501and C 502.

Setting ranges :


Generally installed on the mainline, this valve eliminates down-stream pressure surges and waterhammer during normal startingand stopping of a pump.This valve, whose control is integratedinto the electrical circuit of the pump,opens and closes at a slow, controlledspeed during start up and shut downphases of the pump.Set pressure depends on solenoid valve.

Its role is to protect systemsagainst surges (water hammer),whatever their source, by evacua-ting the water in excess straighta-way.The mechanism consists of a springwhich is adjustable to the correctweighting to hold the valve firmly in place against its seat, keeping itwatertight.

When a pressure wave occurs this causescompression of the spring and the opening of the valve to allow evacuationof the water.

It should be noted that the stem (7) isdesigned to compensate for defect of alignment which could be caused by hydraulic pressure on the valve andby the force of the spring.

This avoids any instability and allows a self centering of the valve seat to centralize itself automatically whenwater passes.

PROGRESSIVE OPENINGAND CLOSUREPrevents overflowing and maintainsa constant level in a reservoir bymeans of a float tap. Opening andclosure are very gradual over thefew centimeters above and belowthe required level.This valve should preferably be installedat the foot of a reservoir or the top of a tank.Connecting pipe 10/12 mm from thefloat tap to the valve not included.(Must be adjusted on measure on site).

Identical to C 701, it guaranteesthe maintenance of sufficient upstream pressure while allowingthe reservoir to be filled when thenetwork permits. (diversion)Connecting pipe 10/12 mm from the pressure float tap to the valve notincluded.(Must be adjusted on measure on site).

NON-MODULATINGWORKS FULLY OPEN-FULLY CLOSEDValve controlled by a solenoidvalve connected to a float switch*.The solenoid (normally closed) isactivated when the float reachesthe low level ; it then re-closes atthe high level.Regulated by volume not by level, this valveis suitable for night-time filling, since the"fullly open - fully closed" principle econo-mizes on energy in the case of supply by apump.

Equipped with non-return valves (checkvalves),• it closes automatically in the event of areturn of water. (C 707 C)• it guarantees the maintenance of sufficientupstream pressure while allowing the reser-voir to be filled when the pressure in the sys-tem allows it (C 727).Working pressure depends on solenoid valve.

PROGRESSIVE OPENING AND CLOSUREPrevents overflowing and main-tains a constant level in a storagetank or reservoir by means of apilot. Both opening and closureare very gradual over the fewcentimeters above and below therequired level.This type of valve should be used whenthe supply pressure is appreciably higher(about 1 bar) than the head developedby a full storage tank or reservoir.

Equipped with non-return valves (checkvalves)• it closes automatically should any waterreturn. (C 201 C)• it opens automatically to reverse waterflow if the upstream pressure becomesless than the downstream pressure. (C 201 DS)

Exists in top-fill or bottom-fill versions.Setting ranges :


NON-MODULATING WORKSFULLY OPEN OR FULLY CLOSEDPrevents overflowing and main-tains a constant maximum level(minimum 1.5 m) in a ground sto-rage tank or reservoir by meansof a pilot.A non modulating valve, it is either fullyopen or fully closed and should be usedwhen the supply pressure is only slightlyhigher than the head developed by thefull tank.

C 801 : Electrically controlledvalve which is normally closed in the absence of power.Used whenever an on/off systemis required.C 802 : Identical to C 801 butnormally open when switched off.Working pressure depends on solenoïdvalve.

This control valve functions as ahydraulic check valve whichopens and closes at a controllableand regulated speed, reducingsudden jumps in pressure.The speed of closure can be regulatedindependently from the speed of opening.Like a conventional non return-valve(check valve), it reduces sudden jumps inpressure should water return (C 1001 C).After pressure jumps have stopped, thenormal flow is restored progressively.

A control valve is a modulating valve which throttlesdepending on the application to maintain a preset upstreamor downstream pressure, a preset flow, a preset fluid level...To correctly size this valve and avoid undesirable operatingcharacteristics (noise, excessive wear, poor regulation) whichresult from oversizing (or undersizing), use the sizing guideand choose the smallest valve size compatible with theindicated flow rates.NOTA :1 - For a throttling valve application requiring a large fluctuant

flow rate, a dual valve installation should be used.2 - The maximum flow rates listed above were calculated by

using a velocity of 4,5 m/second. The throttling valve iscapable of handling larger flows for short periods of time ;however, the increase in maximum flow should be limitedto 25% of the above values.

3 - For C900 series : min. flow 1m/s.

CAVITATION HEADLOSS CHART

A too large differential pressure and alow downstream pressure may result indamage to the valve by cavitation. Toavoid it, refer to the cavitation curve.If necessary take the differential pressurein two or more stages by installing andconnecting directly two or more controlvalves in tandem.

If the differential does not create toomuch cavitation (near the cavitation linein the cavitation zone), option 2 (seepage 14) can be recommended.

1. FAST RELEASE OF AIRWhen a system is filled, the aircontained in the pipes must be eva-cuated.The primary function of the airvalve is therefore to allow a largequantity of air to be evacuated.Because in the beginning the pipesare full of air, the mobile float/valveseat assembly is resting on theshield profile.Thus the air can be evacuatedrapidly through the large orificewithout involving the float/valve seatmechanism.

2. RELEASING AIR UNDERPRESSURE

When the network is under pres-sure, the closing head stays flatagainst the seal. The float alonerises with the level of the waterbecause of the clearance gap inthe sleeve of the float.Thus, as air accumulates in the airvalve the float falls with the levelof the water which frees the smallorifice which acts as a drain. Thisevacuates the air.

3. RAPID INFLUX OF AIRDuring emptying or a burst in the system, there will be sudden loss of pressure in the pipework.The 3rd function is to allow a largequantity of air to enter in order toavoid problems associated withsuch a pressure loss. (Vacuumeffect).A rapid drop of water level occursin the pipework.The float/valve seat mechanismfalls to rest on the aerodynamicshield allowing the air to enter.

All water pipes carryair... This air mayhave been introducedat the time the watersystem was filled, orduring maintenanceworks, but can alsoarise from the wor-king of pumps or dissolved air in reser-voirs...

The installation ofautomatic equipmentsuch as air valves andanti-water hammervalves allows most of the problems caused by air to beresolved.
