Use

 In ventilation and air-conditioning systems for water-side terminal unit control in closed

circuits, e.g. induction units, fan coil units, small reheaters and small re-coolers, for use

in:

 2-pipe systems with one heat exchanger for heating and cooling

 4-pipe systems with two separate heat exchangers for heating and cooling

 In closed-circuit zone heating systems, e.g.

 Individual storeys in a building

 Apartments

 Individual rooms

This compensates for the flow  100 as resistance of the heat exchanger or radiator, so keeping the overall flow rate, V constant as possible.

Orientation 90° 4362Z01 90° Commissioning notes Commission the valve only if the manual knob or actuator has been mounted correctly. Manual adjustment The straight-through path A  AB can be opened electrically via the actuator, or manually. With 3-port valves, this throttles or closes T-bypass B. Manually, path A  AB can only be opened to 70 % (T-bypass closes to 30 %). The valves are closed by a return spring. Maintenance . V..P45..S valves require no maintenance.
