5.1. general description
The 2/2-way globe control valve Type 2301 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).
Follow instructions for use in the EX area!
See chapter "3.1".
The operation of the globe control valve Type 2301 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.

properties

• Direct installation of the positioners Type 8692 / 8694 / 8696 or
the process controller Type 8693.
• Optimum valve selection for the application through three standard
Kv values per line size (up to five 5 Kv values for ½" line size).
• High tightness by self-adjusting packing glands (spindle sealing
element).
• Closes tightly when using the PTFE control cone.
Type 2301
• High flow values by the streamlined valve body made of stainless
steel.
• Generously dimensioned expansion space above the seat to prevent
erosion on the body caused by cavitation.
• Simple and fast replacement of the control cone and the threaded
seat.
• Actuator can be rotated steplessly through 360°.
• Maintenance-free under normal conditions.

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

• The globe series is characterized by screwed-in seats, which can
be used to reduce the orifice of the control valve in particular.
