1 TO MATA CONSTANT FOW C Series PURGE SET FOWMETER WITH CONSTANT FOW VAVE GENERA C series Constant Flow Valves keep flow rate of gases or liquids even when the supply or load pressure changes. Control valve with diaphragm automatically acts following the change of pressure. They are normally delivered together with flowmeter as a "Purge set". Primary(Inlet) pressure variation control type and Secondary(Outlet) pressure variation control type are ready to meet all possible applications. EUP Type Measuring Fluid Max. Fluid Press. (MPa) Max.

The load pressure (Secondary pressure) is connected to the upper chamber. The differential pressure between the lower chamber and the upper chamber is always constant thanks to the function of the Spring and the Diaphragm. The differential pressure across the needle valve is kept always constant and the flow rate of the fluid is proportional only to the opening of needle valve. The opposite action is taken for SECONDARY (ET) PRESSURE VARIATION CONTRO TYPE and the flow rate is kept also constant even when the load pressure changes.

Primary Pressure Variation type Purge set will be suitable in keeping the purging volume of fluid. iquid level in tanks is measured by the Back-pressure at the edge of purging pipe. The outlet pressure at the tank bottom changes depending on the liquid level, and constant bubbling is required. Thus, Secondary Pressure Variation type purge set is used for this application. A DP transmitter is often connected to pressure line instead of pressure gauge for remote transmission.
