Memory Stop on the 142 

series balancing valve

Once you have balanced the flow rate, insert a 2.5 mm hexagonal key into the 
hole (5) in the balancing valve and fully turn it clockwise without forcing it. This 
sets the valve’s maximum stroke position: if necessary, it is possible to shut off 
the balancing valve in the circuit by turning the knob fully clockwise manually. To 
restore the valve to its preset position, turn the adjustment knob fully counter-
clockwise (fig. J).
