FLOW CONTROLS
DESCRIPTION
A manually adjustable, pressure-compensated, bi-directional fl ow control valve.
An internal compensator spool provides compensated fl ow across the proportional
orifi ce regardless of fl ow direction.
OPERATION
The FR12-32 provides regulated fl ow in both directions: from port ➁ to port ➂, or from
port
➂ to port ➁. Port ➀ should be blocked. Regulated fl ow increases from closed to
fully open with clockwise rotation. The valve will maintain the set fl ow rate regardless
of pressure variations at each of the ports.
FEATURES
• Excellent linearity and hysteresis
characteristics.
• Hardened spool and cage for long life.
• Various adjustment options.
