Solenoid Valves Flow Characteristics (How to indicate flow characteristics) 1. Indication of flow characteristics Indication of the flow characteristics in specifications for equipment such as a solenoid valve, etc. is depending on “Table (1)”.
Solenoid Valves Flow Characteristics C b P1 P2 t : Sonic conductance [dm3/(s·bar)] : Critical pressure ratio [—] : Upstream pressure [MPa] : Downstream pressure [MPa] : Temperature [°C] Note) Formula of subsonic flow is the elliptic analogous curve. Flow characteristics curve is indicated in the Graph (1) For details, please use SMC’s “Energy Saving Program”. Example) Obtain the air flow rate when P1 = 0.4 [MPa], P 2 = 0.3 [MPa], t = 20 [°C] for a solenoid valve where C = 2 [dm3/(s·bar)] and b = 0.3.

Solenoid Valves Flow Characteristics 2.3 Flow coefficient Cv factor The United States Standard ANSI/(NFPA)T3.21.3:1990: Pneumatic fluid power—Flow rating test procedure and reporting method for fixed orifice components defines the flow coefficient Cv factor by the following formula which is based on testing conducted with a test circuit analogo us to ISO 6358. Q Cv = ——————————— ·········································································(7) ∆P (P2 + Pa) 114.

Solenoid Valves Flow Characteristics (4) Test method By attaching the equipment for testing with the test circuit shown in Fig. (3) and running water at 5 to 40°C, measure the flow rate with a pressure difference of 0.075 MPa. However, the pressure difference needs to be set with a large enough difference so that the Reynolds number does not go below a range of 4 x 104. By substituting the measurement results for formula (8) to figure out Av.
Flow Characteristics Note) Use this graph as a guide. In the case of obtaining an accurate flow rate, refer to front matter pages 1 to 6. For Air How to read the graph Downstream pressure of valve (P2) MPa The sonic range pressure to generate a flow rate of 100 l/min (ANR) is P1 ≈ 0.1 MPa for a ø3 orifice (VX313), P1 ≈ 0.23 MPa for a ø2.2 orifice (VX312), and P1 ≈ 0.55 MPa for a ø1.5 orifice (VX311).

Glossary of Terms Pressure Terminology 1. Maximum operating pressure differential The maximum pressure differential (the difference between the inlet and outlet pressure) which is allowed for operation, with the valve closed or open. When the downstream pressure is 0 MPa, this becomes the maximum operating pressure. 2. Minimum operating pressure differential The minimum pressure differential (differential between the inlet pressure and the outlet pressure) required to keep the main valve fully opened. 3.
