Fast-coupling pressure test ports The 130 series balancing valve has as
standard probe type, fastcoupling pressure test ports. The probe from the
differential pressure meter is inserted into the port packing, until the end of
the probe enters the system. When the measuring probe is pulled out, the
test port automatically closes, preventing uid leakage. Care should be taken
to pull the probe out slowly so as to allow adequate time for the packing to
re-seal – otherwise uid can quickly escape creating a hazardous situation.
Consult differential pressure meter manufacturer instructions for proper use
of instrument and pressure port couplings.

Operating Principal
The 142 series balancing valve is a hydraulic device that controls the ow rate
of a uid. Turning the knob moves a plug within the uid stream which varies
the ow rate. The ow rate is determined according to the pressure drop
value measured by a differential pressure meter connected to the pressure
test ports and the adjustment knob position.
Memory stop The 130 series balancing valve features a memory stop that
allows the valve to be reopened to the initial position if it has been closed for
any reason such as isolating components in the balanced circuit. Locking the
position to be memorized requires the use of a 2.5 mm hex key.
Adjustment knob The knob is made of a reinforced high strength corrosion-
resistant polymer. The shape of the knob is designed to ensure maximum
comfort for the operator and an accurate adjustment.
Adjustment reference scale Each 360° rotation of the knob moves the
turn indicator by one position, ranging from 0 (valve closed) to 4 (valve fully
open).
