ARI-STEVI® Smart 423 / 463 (DN200-300)

Control valve – 3-way with flanges

Description

eClass-No.:	37010213
Application:	Selection criteria: simple control task, non-critical operating conditions, standard requirements Application: industrial complex, building technology,mechanical engineering
Medium:	Cooling water, cooling brine, warm water, hot water, steam, gas, etc.

Operating principles

The control valves are especially suitable for actuation by pneumatic or electrical actuators.
Depending on the mode of operation, two different execution methods are possible:
1. Execution with mixing plug
2. Execution with diverting plug
The execution with the mixing plug is the standard execution method.
This execution method is to be chosen when the valve is also employed as a mixer
(2 entrances, 1 exit.)
In exceptional cases, the execution with the mixing plug can also be employed as a
diverting plug (1 entrance, 2 exits). This requires, however, low differential pressures and
stable propulsion.
The execution method with the diverting plug is only to be employed with the operation of
diverting.
