Flow Rates
Subject: Flow capacity through ECO VALVE, back pressure/pressure sustaining and
pressure relief valves.
Under continuous flow conditions: @
100 PSI with ambient temperature water with the valve
set@ 50PSIG.
1/4 ” valve 17 USGPM
3/8 ” valve 18 USGPM
1/2 ” valve 19 USGPM
Note: Capacities will increase with pressure. (If pressure is doubled, flow rate will
approximately double)
For capacities of valves with pulsating flow use approximately 1/3 of the above given flow
values.
TEMPERATURE EFFECTS: Thermoplastics and thermosets will decrease in tensile strength as the
temperature increases; therefore, the working pressure must be reduced accordingly. The following factors
will apply:
