ifb series are priority flow regulators.

if used to regulate flow from a fixed supply, the valve will pass the required flow and any surplus flow will be diverted to the bypass port.

the bypass flow may be used for a secondary circuit.

this valve can adjust the flow volume from port 1 to port 3.

with fixed flow, the pressure drop of damping is generated.

the spring is moved by the force of the pressure which is generated by the pressure difference at the two sides of the spool.

whether the pressure requirement of port 2 is higher or lower than the pressure of port 3, the pressure of port 1 shall be higher than the pressure of port 2 or port 3.

rated flow :

90 l/min

see cavity data 12-03

installation :

before screwing the cartridge on the valve body, ascertain to provide suitable gasket lubrication with clean oil and also be sure to screw the cartridge manually in to reach against the gaskets in the valve body.
