Structure and function
Typ 2300
6 STRUCTURE AND FUNCTION
The angle-seat control valve Type 2300 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 incorporated directly. Via a dowel pin, the
control cone is modularly coupled to the actuator spindle for quick
changeovers. The ow direction is always below seat.
6.2 Function
The seat of the valve is always closed against the medium ow.
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 dened position is reached.
▶To ensure a controlled restart, rst 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 ow 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
contributes 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”).

8.3.4 Rotating the actuator
The position of the connections can be aligned steplessly by
rotating the actuator through 360°.
Only the entire actuator can be rotated. The control unit
cannot be rotated contrary to the actuator.
NOTE!
Damage to the seat seal or the seat contour!
▶When rotating the actuator, ensure that the valve is in open
position.
Procedure:
→Clamp the valve body in a holding device (applies only to
valves which have not yet been installed).
→Control function A:
Without unit control: pressurize the pilot air port 1 with com-
pressed air (5 bar): valve opens.
With unit control: open the valve according to the operating
instructions for the control unit.
→Counter on the ats of the nipple with a suitable open-end
wrench.
WARNING!
Risk of injury from discharge of medium and pressure!
If the direction of rotation is wrong, the body interface may become
detached.
▶Rotate the actuator module in the specied direction only (“Fig.
7”)!
→Place suitable open-end wrench on the hexagon of the
actuator.
→Rotate counter-clockwise (as seen from below) to bring the
actuator into the required position.

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 pres-
sure and temperature range.
▶Observe the data sheet specications from the hose
manufacturers.
The pneumatic connection of the angle-seat 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.
