possible only in combination with a control unit.
Possible control units are:
Positioner Type 8692, 8694 and 8696
Process controller Type 8693
6.1. Structure
The angle-seat control valve consists of a pneumatically operated
piston actuator, a control cone and a 2/2-way angle-seat body.
Via a dowel pin, the control cone is modularly coupled to the
actuator spindle for quick changeovers.
For the body, almost any line connections are possible.
A threaded port and a welded end are offered as a standard version.
The valve seats are incorporated directly. The flow inlet is always
under seat.
The description of the control function (CF) can be found in
chapter entitled “6.2.1. Control functions (CF)”.

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.
Control function A (CFA)
Normally closed by spring action.

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
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 entitled “7.4.3. Pressure ranges”.
