TO MAINTAIN LIQUID FLOW RATE

CX-1510 Series
FLOW SET VALVEFOR LIQUID APPLICATIONOUTLINE
CX-1510 FLOW SET VALVE is a constant flow valve for liquids ofwater or equivalent for water.
Even inlet or outlet pressure of process changes, CX-1510 maintains constant flow of liquid. CX-1510 is suitable for the stablesupply of the water supply line of various facilities.

OPERATION PRINCIPLE
Water flow is introduced from inlet with pressure of P1.
The Inlet pressure P1 actuates the pressure sensing plate. The
pressure sensing plate is connected to valve needle. A spring isassembled onto this valve needle unit.
The assembled spring acts so as to keep the differential pressure
P2 constant and to keep constant flow even when outlet pressure
P3 changes.
