Flow-rate Characteristics Fluid and Ambient Temperature Valve Leakage Rate Internal Leakage External Leakage EPDM Seal material Leakage rate (Water) Note) 0.1 cm3/min or less EPDM Seal material Leakage rate (Water) Note) 0.1 cm3/min or less Note) Leakage is the value at ambient temperature 20°C. Note) With no freezing Ambient temperature (°C) .20 to 60 Fluid temperature (°C) 1 to 99 N.C. For Heated Water Symbol 2 1 . Can be used with air (up to 99°C) and water. Note that the maximum operating pressure differential and flow-rate characteristics should be within the specifications of the fluid used. When the valve is closed, flow is blocked from port 1 to port 2. However, if the pressure in port 2 is higher than port 1, the valve will not be able to block the fluid and it will flow from port 2 to port 1. Normally Closed (N.C.) Note 1) The operation of the valve may be unstable due to the capacity of the pressure supply source such as pumps and compressors or the pressure loss by the orifice of piping. Please contact SMC to check if the required valve size can be used in the application. Please contact SMC for the compatibility of the circuit flow and valve size. (Refer to page 23.)
