Siemens 2-port and 3-port valves PN 16 CE1N4845en
Building Technologies 2018-11-05
We recommend installation in the return pipe, as the temperatures in this pipe are lower
for applications in heating systems, which in turn, extends the stem sealing gland’s life.
Always use a strainer upstream of the valve to increase the valve’s functional safety.
Mounting notes
Both valve and actuator can easily be assembled at the mounting location. Neither
special tools nor adjustments are required.
The valve is supplied with Mounting Instructions 4 319 9526 0.

Commissioning notes
Commission the valve only if the manual knob or actuator has been mounted
correctly.
The straight-through path A
→ AB can be opened electrically via the actuator, or
manually. With three-port valves, this throttles or closes bypass B.
Manually, path A → AB can only be opened to 70 % (bypass closes to 30 %). The
valves with k
vs
values 10, 16 and 25 can be fully opened whereas the bypass can be
fully closed.
The valves are closed by a return spring.
Maintenance
V..P45.. valves require no maintenance.
When doing service work on the valve / actuator:
• Deactivate the pump and turn off the power supply
• Close the shuttoff valves
• Fully reduce the pressure in the piping system and allow pipes to completely cool
down
If necessary, disconnect the electrical wires.
Before putting the valve into operation again, make certain the manual knob or the
actuator is correctly fitted.
The stem sealing gland cannot be exchanged. In the case of leakage, the entire valve
must be replaced. Contact your local office or branch.
Disposal
Do not dispose of the device as household waste.
Warning
Due to the tensioned spring return, valve disassembly may result in flying parts
causing possible injury.
Only authorized staff may disassemble valves with tensioned spring return!
Disposal
• Special handling of individual components may be mandated by law or
make ecological sense.
• Observe all local and currently applicable laws and regulations.
