incl. 1½" union nut for the installation on a PAW modular distribution manifold.With PAW mounting equipment the heating circuit can be installed on wall brackets.
Large ball valve
easy handling, visible closing position
4-way mixing valve
completely made of brass, when installed individually it is suited for the operation of a boiler circuit pump (a change in the boiler circuit with closed flow line is possible).When installed on a distribution manifold the return line of the mixing valve must be equipped with a non return valve to avoid unwanted circulation.
For mounting actuators of other manufacturers, you need the adapter set item no. 705580.
PAW actuator SR5
with 1.5 m cable and mounting set for snap-in assembly on the mixing valve, suited for flow on the right or left side, change-over switch for manual / automatic operation, supply 230 V / 50 Hz, torque 5 Nm
EnEV-compliant functional insulation
made of durable elastic EPP, complete insulation of valves and fittings, ventilation opening to cool the pump
Free access to the pump head
by simply removing the front insulation shell
Check valve in the return pipe
can be opened, 200 mm wc, spring-loaded, thus suited for horizontal and overhead installation
Flow on the right = standard
Flow and return line can be changed on site, also for heating circuits with mixing valve
All water-carrying parts are made of brass
Full metal thermometers
can be pulled off, with immersion sleeve integrated in the ball valve
PAW heating pumps with high-efficiency (ECM) technology
fitted with 2 m cable, completely premounted, integrated in the insulation, pressure tested, with serial number, perfectly designed system, pump characteristics, EuP/ErP READY
Pump can be isolated,
so that it can be replaced without draining
