Solenoid Valves Flow Characteristics
(How to indicate flow characteristics)
Conversion of flow coefficient:
Av = 28 x 10–6 Kv = 24 x 10–6Cv ···········································································(11)
Here,
Kv factor: It is the value representing the flow rate of clean water in m3/h which runs through the valve at 5 to 40°C, when the
pressure difference is 1 bar.
Cv factor (Reference values): It is the value representing the flow rate of clean water in US gal/min which runs through the valve
at 60°F, when the pressure difference is 1 lbf/in2 (psi).
Values of pneumatic Kv are different from Cv because the testing method is different from each other.

Example 1)
Obtain the pressure difference when 15 [l/min] of water runs through the solenoid valve with an Av = 45 x 10–6 [m2].
Since Q0 = 15/45 = 0.33 [l/min], according to the Graph (2), if reading P when Q0 is 0.33, it will be 0.031 [MPa].
Example 2)
Obtain the flow rate of saturated aqueous vapour when P1 = 0.8 [MPa], P = 0.008 [MPa] with a solenoid valve with an Av =1.5 x
10–6 [m2].
According to the Graph (2), if reading Q0 when P1 is 0.8 and P is 0.008, it is 0.7 [kg/h]. Hence, the flow rate Q = 0.7 x 1.5 = 1.05
[kg/h].
