position (fig. K)

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).
