Product Overview
2/10
Siemens Building Technologies Two-port and three-port small valves PN16, ANSI Class 250 CM1N4845E
HVAC Products 11.2001
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:
− Two-pipe systems with one heat exchanger for heating and cooling
− Four-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
• Hot water: Max. 110 °C, short-term max. 120 °C
• Chilled water: Above 2 °C
• Water containing anti-freeze agent
Water should be treated as specified in VDI 2035
Max. 1600 kPa (16 bar) in accordance with ISO 7268 (DIN 2401) and ANSI Class 250
as per ASME B16.15.

For ∆p

= Where ∆p
max
is above 100 kPa, there is an increased risk of noise and erosion
on the seat and plug.
∆p
s
= Max. admissible pressure differential in kPa at which the valve is still capable of closing
against the pressure.
∆p
