Operating Principle
The 142 is a variable orifi ce balancing valve for hydronic heating and cooling
systems, plus low lead for plumbing circuits. Characterized fl ow plug which
provides precise system balancing valves and highly accurate fl ow verses
other setters with ball valve control.
A compact body design with integral PT ports, a memory stop feature
designed to accurately lock valve settings, with a hex key, enabling the valve
to be closed and re-opened to the exact pre-set position which eliminates
the need for rebalancing after servicing, heat and impact resistant glass-
reinforced nylon adjustment knob, EPDM valve plug seal for accurate control
and tight shut-off for isolation purposes.
The fl ow rate is determined according to the pressure drop valve measured
by a differential pressure meter connected to the pressure test ports.
Memory stop feature
Characterized plug for smooth adjustment.
Maximum working pressure: 232 psi.
Working temperature range: 14—250°F.
DZR low-lead brass body.

Memory Stop
Each 360 degree rotation of the adjustment knob moves the turn indicator
by one position, ranging from 0 (valve closed) to 4 (valve fully open). After
adjusting the fl ow rate, insert a 2.5 mm hex key in the hex hole, fully turn it
clockwise without forcing it. This sets the valve's maximum stroke position.
If necessary, it is possible to shutoff the balancing valve by turning the
adjustment knob fully clockwise manually. To restore the valve to the pre-set
position, turn the adjustment knob fully counter-clockwise.
