Type 2000 INOX
Structure and function
7. STRUCTURE AND FUNCTION
7.1. Structure
The angle seat valve consists of a pneumatically actuated piston
actuator with optical position indicator and a 2/2-way valve housing.
7.2. Function
Depending on the version, the valve is closed against the medium
flow by spring force (control function A, SFA) or by control pressure
(control function B, SFB).
Spring force (SFA) or pneumatic control pressure (SFB) generates
the closing force on the pendulum disc. The force is transferred via a
spindle which is connected to the actuator piston.
Flow inlet under seat:
As the medium pressure is under the pendulum disc, this pressure contributes to the opening of the valve. The flow inlet is under the valve seat.
If the minimum control pressure is too low for SFB or the permitted
medium pressure is exceeded, leaks may occur!
7.2.1. Control functions
Control function A (SFA)
Closed in rest position by spring force.
Control function B (SFB)
Open in rest position by spring force.
8. ASSEMBLY
8.1. Safety instructions
DANGER!
Risk of injury from high pressure in the system!
• Turn off the pressure and vent the lines before loosening lines
or valves.
WARNING!
Risk of injury from improper assembly!
• Installation must only be carried out by authorized technicians
and with the appropriate tools!
Risk of injury from unintentional activation of the system and
uncontrolled restart!
• Secure system from unintentional activation.
• Following assembly, ensure a controlled restart.
Risk of crushing from moving pneumatic connection!
• When opening and closing the device, do not touch the moving
pneumatic connection.
• Do not reach into the area immediately above and below the
control air connection.

8.2.1. Preparatory tasks
→ Clean pipelines (sealing material, swarf, etc.).
Welded housing:
→ Before welding in the valve housing, remove the actuator
(see Chapter "8.3.1").
8.3. Installation
8.3.1. Remove actuator from the valve
housing (for welded housings only)
WARNING!
Risk of injury from damaged devices!
If the wrong tools are used for assembly work, the device may be
damaged.
• To remove the actuator from the valve housing, use an open-end
wrench, never a pipe wrench.
Control function A:
→ Pressurize control air connection with compressed air (5.5 bar)
so that the pendulum disc is lifted off the valve seat and is not
damaged.
Control function B:
For control function B it is not necessary to apply compressed air for
installation.
NOTE!
Damage to the seat seal or the seat contour!
• When removing the actuator, ensure that the valve is in the
open position.
→ When valve is in open position, remove actuator from the valve
housing using an open-end wrench (see "Fig. 4").

Assembly
WARNING!
Risk of injury from damaged devices!
If the wrong tools are used for assembly work, the device may be
damaged. Also if tightening torque is incorrect.
• To remove the actuator from the valve housing, use an open-end
wrench, never a pipe wrench.
• Observe tightening torque (40 ± 3 Nm)
→ Grease pipe thread before re-installing the actuator
(e.g. with Klüber paste UH1 96-402 from Klüber).
→ For control function A: Pressurize control air connection with
compressed air (5.5 bar) so that the pendulum disc is lifted off the
valve seat and is not damaged when screwed in.
→ Screw actuator into the valve housing.
Observe tightening torque (40 ± 3 Nm)!
If the position of the control air connection for installation
of the hose is unfavorable, it can be aligned steplessly by
rotating the actuator through 360°.
8.4. Pneumatic connection
DANGER!
Risk of injury from high pressure in the system!
• Before disconnecting lines and valves, turn off the pressure 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.
8.4.1. Control air connections
The 45° angle connection, which can be ordered
separately, is recommended for the control air
connection!
In this case the free-moving hose length should be
min. 250 mm.
Order no.
903383
If the hose length is shorter, the durability and
function of the plug-in coupling will be impaired!
If a straight control air connection is used, the freemoving hose length should be min. 400 mm.
If the hose length is shorter, the durability and
function of the plug-in coupling will be impaired!
Risk of crushing!
• Due to the risk of crushing, a 90° control air connection must not be used!
