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.

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 (Kv
ratios can be realized.
• Kv value, i.e. the smallest Kv value at which the angularity tol-

erance according to DIN IEC 534-2-4 is still maintained:
≤ DN20
Kv at 10 % of the stroke
R
> DN20
Kv 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
