Description
The valve type MH2FR is a 2-way flow control valve for
block design installation. It is used for pressure and
temperature independent flow stabilization. If the direction
of flow runs from 1 to 2 through the valve, the pressure in
channel 1 exerts force on the pressure compensator. The
pressure compensator moves to the control position until
the forces are balanced. If the pressure in channel 1 or 2
changes, the pressure compensator keeps readjusting and
thereby maintains a constant pressure drop and the
unchanging cross-section of the throttling point provide for
a constant flow. In the direction of flow from 2 to 1, the
return flow runs freely via the throttling point.
Characteristic curve
At the beginning of control (8 bar), the stated flow is
present with a tolerance of +35% / -5%
