Product description
5 PRODUCT DESCRIPTION
5.1 General description
The 2/2-way angle-seat control valve Type 2300 is suitable for liquid
and gaseous media.
It uses neutral gases or air (control media) to control the flow of
water, alcohol, oil, fuel, hydraulic fluid, saline solution, lye, organic
solvent and steam (flow media).
The operation of the angle-seat control valve Type 2300 is possible
only in combination with an control unit. Possible control units are:
Positioner Type 8692, 8694 and 8696
Process controller Type 8693
5.2 Versions
There are 2 versions of the angle-seat control valve Type 2300.
• Standard version – without separate Ex type label.
The standard version must not be used in the potentially explosive
area.
• Ex version – with separate Ex type label.
The Ex version may be used in the potentially explosive area. In
doing so, observe the specifications on the separate Ex type label
and the additional information enclosed with the device together
with safety instructions for the Ex area.
5.3 Properties
• Direct installation of the positioners Type 8692 / 8694 / 8696 or
the process controller Type 8693.
• High tightness by self-adjusting packing glands (spindle sealing
element).
• Closes tightly when using the PTFE control cone.
• High flow values by the streamlined valve body made of stainless
steel.
• Simple and fast replacement of the control cone.
• Actuator can be rotated steplessly through 360°.
• Maintenance-free under normal conditions.
5.3.1 Technical features
• Characteristic: modified equal-percentage flow characteristic.
• Theoretical setting ratio (KvS / Kv0) 50:1; alternatively, other setting
ratios can be realized.
• KvR value, i.e. the smallest Kv value at which the angularity tol-
erance according to DIN IEC 534-2-4 is still maintained:
≤ DN20 KvR at 10 % of the stroke
> DN20 KvR at 5 % of the stroke
5.3.2 Options
Control unit: Depending on the requirement, control units in various
designs are available.
• Positioner Type 8692, 8694 and 8696
• Process controller Type 8693

Structure and function
6 STRUCTURE AND FUNCTION
The operation of the angle-seat control valve Type 2300 is
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)”.

Structure and function
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.
Control function B (CFB)
Normally open by spring action.
Control function I (CFI)
Actuating function via reciprocal pressurization.

Technical data
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”.
