5.3 Information on the internet
The operating instructions and data sheets for Type 2301 can be found
on the Internet at: www.burkert.com
6 STRUCTURE AND FUNCTION
The globe control valve Type 2301 can be operated only in
combination with the following control units:
Positioner Type 8692, 8694, 8696 and 8792
Process controller Type 8693 and 8793
6.1 Structure
The valve seats are screwed in. A reduction in the orifices of the seats
can be achieved by simply exchanging the threaded seats. The flow
direction is always below seat.
6.2 Function
The seat of the valve is always closed against the medium flow.
Spring force (CFA) or pneumatic pilot pressure (CFB and CFI) gen-
erates the closing force on the control cone. The force is transferred
via a spindle which is connected to the actuator piston.
6.2.1 Control functions (CF)
WARNING!
For control function I – Danger if pilot pressure fails!
For control function I control and resetting occur pneumatically. If
the pressure fails, no defined position is reached.
▶To ensure a controlled restart, first pressurize the device with pilot
pressure, then switch on the medium.

6.2.2 Flow direction below the seat
Depending on the version, the valve is closed against the medium
flow with spring force (control function A, CFA) or with pilot pressure
(control function B or I, CFB or CFI).
As the medium pressure is under the control cone, this pressure con-
tributes to the opening of the valve.
WARNING!
Medium may be discharged if minimum pilot pressure is too
low or medium pressure too high!
If the minimum pilot pressure is too low for CFB and CFI or the
permitted medium pressure is exceeded, leaks may occur.
▶Observe minimum pilot pressure.
▶Do not exceed medium pressure (see chapter “Pressure ranges”).

WARNING!
For control function I – Danger if pilot pressure fails!
For control function I control and resetting occur pneumatically.
If the pressure fails, no defined position is reached.
▶To ensure a controlled restart, first pressurize the device with pilot
pressure, then switch on the medium.
Risk of injury from unsuitable connection hoses!
Hoses which cannot withstand the pressure and temperature range
may result in hazardous situations.
▶Use only hoses which are authorized for the indicated pressure
and temperature range.
▶Observe the data sheet specifications from the hose manufacturers.
The pneumatic connection of the globe control valve can
be carried out only in connection with the appropriate
control unit.
Possible control units are:
Positioner Type 8692, 8694, 8696 and 8792
Process controller Type 8693 and 8793
8.4.1 Connection of the control medium
→Connect the control medium to the pilot air port (“Fig. 8”: 1)
(3 – 7 bar; instrument air, free of oil, water and dust).
→Fit the exhaust line or a silencer to the exhaust air port
(“Fig. 8”: 3) and, if available, to the additional exhaust air port
(“Fig. 8”: 3.1).
If used in an aggressive environment, we recommend
conveying all free pneumatic connections into a neutral
atmosphere with the aid of a pneumatic hose.

6 AUFBAU UND FUNKTION
Das Geradsitzregelventil Typ 2301 kann nur in Kombination
mit folgenden Ansteuerungen betrieben werden:
Positioner Typ 8692, 8694, 8696 und 8792
Prozessregler Typ 8693 und 8793
6.1 Aufbau
Die Ventilsitze sind eingeschraubt. Reduzierte Sitznennweiten sind
durch den Austausch der Einschraubsitze einfach zu realisieren. Die
Anströmung ist immer unter Sitz.
6.2 Funktion
Der Sitz des Ventils wird immer gegen den Mediumsstrom geschlossen.
Federkraft (SFA) oder pneumatischer Steuerdruck (SFB und SFI)
erzeugen die Schließkraft auf den Regelkegel. Über eine Spindel, die
mit dem Antriebskolben verbunden ist, wird die Kraft übertragen.
6.2.1 Steuerfunktionen (SF)
WARNUNG!
Bei Steuerfunktion I – Gefahr bei Steuerdruckausfall!
Bei Steuerfunktion I erfolgt die Ansteuerung und Rückstellung
pneumatisch. Bei Druckausfall wird keine definierte Position erreicht.
▶Für einen kontrollierten Wiederanlauf das Gerät zunächst mit
Steuerdruck beaufschlagen, danach erst das Medium aufschalten.
