Check Valve - TiEmme 5535 Hoja De Instrucciones

2.3 CHECK VALVE

The check valve avoids flow return when the pump is off.
2.4 SAFETY THERMOSTAT (OPTIONAL)
2.5 ADJUSTABLE REGULATION BY-PASS (OPTIONAL)
During the operation the mark be directed in horizontal
position. The spot must be under the mark. In this case the
flow goes only in the direction of the arrow.
For filling, emptying and bleeding the mark must be
directed in vertical position . The spot must be on the left
of the mark. In this case the flow goes in both directions.
Norm EN 1264 requires that there is a security for stop
the circulation when the temperature of the water go up
the 55°C (section 4.1.2.8.2). This norm
temperature radiant systems. The article 5535 can be
provide with a safety thermostat that operate at 55°C. It
is proved with connection cable and it is recommend
connect in serial with pump.
Adjustable regulation by-pass, if
necessary, must be mounted on
the return way and it is used to
control the total head in the
secondary supply circuit. When the
set differential pressure value is
reached, the obturator opens and
allow fluid to pass from the flow to
the return circuit, keeping the
pressure differential at the set
value.
Adjustable
optional.
The regulation is possible between
50 and 400 mbar.
