General information
General hazardous situations.
To prevent injury, ensure that:
▶The system cannot be activated unintentionally.
▶Do not use in areas which are prone to vibrations.
▶Installation and repair work may be carried out by authorized
technicians only and with the appropriate tools.
▶After an interruption in the power supply or pneumatic supply,
ensure that the process is restarted in a defined or controlled
manner.
▶The device may be operated only when in perfect condition and
in consideration of the operating instructions.
▶The general rules of technology apply to application planning

Product description
5 PRODUCT DESCRIPTION
5.1 General description
The externally controlled angle seat valve type 2000 / globe valve type
2002 is suitable for liquid and gaseous media.
It uses neutral gases or air (control media) to control the flow-rate
of water, alcohol, oil, fuel, hydraulic fluid, saline solution, lye, organic
solvent and steam (flow media).
5.2 Properties
• High tightness by self-adjusting packing glands (spindle sealing
element).
• High seat tightness by swivel plate.
• High flow values by the streamlined valve body made of stainless
steel.
• Actuator can be rotated steplessly through 360°.
5.2.1 Options
• Activation unit
Different versions of the activation units are available depending
on the requirement.
• Stroke limitation
Limit of the maximum open position/flow rate by means of
adjusting screw.
• Feedback indicator
The device features mechanical limit switches or inductive prox-
imity switches.
5.2.2 Device versions
The angle seat valve / globe valve is available for the following actuator
sizes:
Type 2000: ø 40 mm to ø 125 mm
Type 2002: ø 50 mm to ø 125 mm
5.2.3 Restrictions
WARNING!
Risk of injury from water hammer.
A water hammer could crack the lines and device.
▶Use valves with flow inlet above seat for gaseous media and
steam only.

Structure and function
6 STRUCTURE AND FUNCTION
6.1 Structure
The angle seat valve / globe valve consists of a pneumatically actuated
piston actuator and a 2-way valve body / 3-way valve body. The actuator
is manufactured from PA or PPS. The tried and tested, self-adjusting
packing gland ensures high tightness. The flow-enhancing valve body
made of stainless steel or red bronze enables high flow values.

6.2 Function
Depending on the version, the seat of the valve is closed with or against
the medium flow.
Spring force (CFA) or pneumatic control pressure (CFB and CFI)
generates the closing force on the swivel plate. The force is transferred
via a spindle which is connected to the actuator piston.

WARNING!
For control function I – Danger if control 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
control pressure, then switch on the medium.

Structure and function
6.2.3 Incoming flow below seat
Depending on the version, the valve is closed against the medium
flow by spring force (control function A, CFA) or by control pressure
(control function B, CFB).
As the medium pressure is under the swivel plate, this pressure
contributes to the opening of the valve.
WARNING!
Leaking seat if minimum control pressure is too low or
medium pressure too high.
If the minimum control pressure is too low for CFB and CFI or the
permitted medium pressure is exceeded, the seat may leak.
▶Observe minimum control pressure.
▶Do not exceed medium pressure.
▶See chapter „7.5.2. Pressure ranges“.
CFA/CFI CFB/CFI
Fig. 2: Incoming flow below seat (closing against medium)
6.2.4 Incoming flow above seat
The valve is closed by spring force (control function A, CFA) with
the medium flow. As the medium pressure is over the swivel plate, it
supports the closing process of the valve and also contributes to the
sealing of the valve seat.
The valve is opened by the control pressure.
WARNING!
Risk of injury from water hammer.
A water hammer could crack the lines and device.
▶Use valves with flow inlet above seat for gaseous media and
steam only.
To ensure complete opening, the minimum control pressure
must be used!

8.1 Safety instructions
DANGER!
Risk of injury from high pressure in the equipment.
▶Before dismounting pneumatic lines or valves, turn off the pres-
sure and vent the lines.
WARNING!
Risk of injury from improper assembly.
▶Installation may be carried out by authorized technicians only
and with the appropriate tools!
Risk of injury from unintentional activation of the system and
an uncontrolled restart.
▶Secure system from unintentional activation.
▶Following assembly, ensure a controlled restart.
WARNING!
For control function I – Danger if control 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
control pressure, then switch on the medium.
8.2 Before installation
• Any installation position is possible, preferably with actuator face up.
• Before connecting the valve, ensure the pipelines are flush.
• Observe direction of flow (see type label).
8.2.1 Preparatory work
→Clean pipelines (sealing material, swarf, etc).
Devices with welded body:
Removing the actuator from the valve body:
→Clamp valve body into a holding device.
NOTE!
Damage to the seat seal or the seat contour!
▶When removing the actuator, ensure that the valve is in the
open position.
→Control function A and I:
Pressurize lower control air connection with compressed air
(5 bar): Valve opens.

Assembly
8.3 Installation
WARNING!
Risk of injury from improper installation.
Assembly with unsuitable tools or non-observance of the tightening
torque is dangerous as the device may be damaged.
▶For installation use an open-end wrench, never a pipe wrench.
▶Observe the tightening torque (see “Tab. 9: Tightening
torques”).
Devices with approval in accordance with DIN EN 161
In accordance with DIN EN 161 "Automatic shut-off valves for gas
burners and gas installations" a dirt trap must be connected upstream
of the valve and prevent the insertion of a 1 mm plug gauge.
8.3.1 Installing the body
Welded body:
→Weld valve body in pipeline system.
Other body designs:
→Connect body to pipeline.
8.3.2 Installing the actuator (welded body)
Graphite seal
Fig. 18: Graphite seal
→Check graphite seal and, if required, replace. Remove all
residues when replacing seal.
WARNING!
Danger if incorrect lubricants used.
Unsuitable lubricant may contaminate the medium. In oxygen
applications there is a risk of an explosion!
▶In specific applications, e.g. oxygen or analysis applications, use
appropriately authorized lubricants only.
→Grease nipple thread before re-installing the actuator
(e.g. with Klüber paste UH1 96-402 from Klüber).
NOTE!
Damage to the seal on the swivel plate!
▶When installing the actuator, ensure that the valve is in the open
position.

8.3.3 Rotating the drive
The position of the connections can be aligned steplessly by rotating
the drive through 360 °.
NOTE!
Damage to the seal on the swivel plate!
▶When turning the actuator, ensure that the valve is in the open
position.
Procedure:
→Clamp the valve body into a holding device (applies only to valves
not yet installed).
→For control function A and I pressurize the lower control air con-
nection with compressed air (5 bar): Valve opens.
→Using a suitable open-end wrench, counter the wrench flat on
the pipe.
→Place a suitable open-end wrench on the hexagon of the actuator
(see “Fig. 19”).
WARNING!
Risk of injury from discharge of medium and pressure.
If the direction of rotation is wrong, the body interface may
become detached.
▶Turn the actuator in the specified sense of direction only
(see “Fig. 19”).

8.4 Pneumatic connection
DANGER!
Risk of injury from high pressure in the equipment!
▶Before dismounting pneumatic lines or valves, turn off the pres-
sure and vent the lines.
WARNING!
Risk of injury from unsuitable connection hoses!
Hoses which cannot withstand the pressure and temperature
range may result in hazardous situations.
▶Use only hoses which are authorized for the indicated pressure
and temperature range.
▶Observe the data sheet specifications from the hose
manufacturers.
For control function I – Danger if control 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
control pressure, then switch on the medium.
8.4.1 Connection of the control medium
If the position of the control air connections is unfavorable
for installation of the hoses, these can be steplessly aligned
by turning the actuator through 360°.
The procedure is described in chapter “8.3.3 Rotating the
drive”.
Control function A: On the lower connection of the actuator.
Control function B: On the upper connection of the actuator.
