Intended use
3. INTENDED USE
The manually actuated valve types 2000, 2012, 2702 and 2712 are
designed to control the flow rate of liquid media.
• Observe the permitted application conditions for using the equipment.
• Operate only when in perfect condition and pay attention to correct
storage, transportation, installation and operation.
Danger – high pressure!
• Turn off the pressure and vent the lines before loosening lines
or valves.
To prevent injuries/damage:
• Secure system/equipment from unintentional activation.
• Only supply fluids into the media connections that are specified
in section “5. Technical data”.
• Do not make any internal or external changes.
• Only trained technicians may perform installation and maintenance
work.
• Do not apply a mechanical load to the body.
• Observe the general regulations of technology.

Structure and Function
6. STRUCTURE AND FUNCTION
6.1. Structure
The valve consists of a manual actuator and a 2/2-way valve body.
By manually actuating the handwheel, the force is transferred via a
spindle and the valve is opened or closed.
6.2. Valve types
Handwheel with
position indicator
(optional)
Opening for
lock

= valve opening in mm
6.3. Handwheel
Each revolution of the handwheel changes the valve position by
1.5 mm (see “Fig. 3”). Clockwise rotation closes the valve, counterclockwise rotation opens it.
Only a low torque of
5–10 Nm is required to seal the valve.
6.4. Position indicator
The value of the display is a distance in mm, usually the current
valve stroke (valve opening in mm). The display after the vertical line
shows the steps in 1/10 mm.
To set a defined flow, please refer to the flow characteristics or the
Kv value table (see data sheet).
If valves feature an interlock, the set position can be secured with a
lock.

6.4.1. Setting the position indicator
The display has been set at the factory so that the value 0,000 is
shown when the valve is tightly closed.
Any valve position can be defined as the zero position:
→ Move valve to the required position by turning the handwheel.
→ Loosen the 3 setscrews on the circumference of the locking ring.
→ Set display by simultaneously holding the handwheel and turning
the locking ring to the value 0,000.
→ Clamp locking ring with the 3 setscrews.
7. ASSEMBLY
DANGER!
Risk of injury from high pressure in the system.
• Before loosening lines or valves, turn off the pressure and vent
the lines.
7.1. Preparatory work
→ Observe flow direction (see type label).
→ Clean pipelines (sealing material, swarf, etc.).
Devices with welded body:
Remove the actuator from the valve body:
→ Open valve by approx. 2 revolutions (to relieve the valve seat seal)
→ Place a suitable open-end wrench on the wrench flat of the nipple.
→ Unscrew the actuator off the valve body.
Devices with socket body:
→ Only disassemble the actuator if required by the customer.

Assembly
7.2. Installation
WARNING!
Risk of injury from improper installation!
Damaged parts or incorrect tightening torques can cause leaks on
the equipment.
• Use an open-end wrench for the assembly.
• Observe the tightening torque (see torque table).
7.2.1. Installing the body
Any installation position, preferably with handwheel face up.
Welded body:
→ Weld valve body in pipeline system.
Other body designs:
→ Connect valve body to pipeline.
7.2.2. Installing the actuator (Welded Body)
→ Check graphite seal and, if required, replace. Ensure that sealant
residue cannot get into the pipeline system.
Graphite seal
→ Lubricate the nipple thread before reinstalling the actuator
(e.g. with Klüberpaste UH1 96-402 produced by Klüber).
→ Observe the torques when screwing the actuator into the valve
body (see “Tab. 1”).
