MODULATING FLOAT<br />
CONTROL VALVE, <strong>E5<strong>10</strong>0</strong>-<strong>10</strong><br />
Envotec <strong>E5<strong>10</strong>0</strong>-<strong>10</strong> Pilot Operated <strong>Modulating</strong> <strong>Float</strong> <strong>Control</strong><br />
<strong>Valve</strong> designed to maintain water level in a reservoir or tank.<br />
Buoyancy of float pilot assembly throttles main valve to open<br />
on a lowering water level and throttles to close upon a rising<br />
water level. The valve proportionately begins to close upon a<br />
rising water level and drip-tight at the maximum level reached.<br />
The float pilot assembly is remotely (inside water tank) installed<br />
where the main valve installed externally is inter-connected with<br />
a sensing tube field installed to operate main valve.<br />

CAVITATION CURVE<br />
Too high pressure loss and too low downstream<br />
pressure may cause valve deterioration. To determine if<br />
cavitation is due to pressure conditions, it is necessary<br />
to refer to cavitation curve. Just in case reduce ∆p by<br />
installing more cascade flow control valves will help<br />
valve to work outside cavitation zone.<br />
A. Cavitation free zone<br />
B. Cavitation zone<br />
Kv FACTOR<br />
Kv factor values expressed in m3/h are intended for fully open valve and refer to flow rate which passing through the valve, causes<br />
a pressure loss equal to 1 bar.<br />

INSTALLATION REQUIREMENTS<br />
Recommended to install valves in horizontal position.<br />
Avoid installing valves 6" and above in a vertical discharge position.<br />
If your installation requires vertical position, Consult factory or specify<br />
at the time of order.<br />
MAINTENANCE REQUIREMENTS<br />
An Isolation valve (Gate valve/Butterfly valve/Ball valve) should be installed before the automatic float<br />
control valve for easy maintenance without draining the piping system.<br />
