The 2/2-way angle seat valve Type 2000 INOX is suitable for liquidand gaseous media.

The angle seat valve, Type 2000 INOX, conforms to the EU Directives according to the EU Declaration of Conformity

It uses neutral gases or air (control media) to control the flow-rate ofwater, alcohol, oil, fuel, hydraulic fluid, saline solution, lye, organic
solvent and steam (flow media).

6.2

5.2

The applied standards, which are used to demonstrate compliancewith the EU Directives, are listed in the EU type test certificate and/or the EU Declaration of Conformity.

Properties

Standards•• High leak-tightness.
•• High flow values.
•• Control air connection can be rotated centrally and steplessly
through 360°.
•• Optical position indicator•• Maintenance-free

STRUCTURE AND FUNCTION

8ASSEMBLY

7.1

Structure

8.1

Safety instructions

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, CFA) or by control pressure(control function B, CFB).

DANGER!
Risk of injury from high pressure in the system!
▶▶ Turn off the pressure and vent the lines before loosening
lines or valves.
WARNING!

Spring force (CFA) or pneumatic control pressure (CFB) generates
the closing force on the pendulum disc. The force is transferred via
a spindle which is connected to the actuator piston.

Risk of injury from improper assembly!
▶▶ Installation must only be carried out by authorized technicians and with the appropriate tools!

Flow inlet under seat:

Risk of injury from unintentional activation of the system anduncontrolled restart!
▶▶ Secure system from unintentional activation.
▶▶ Following assembly, ensure a controlled restart.

As the medium pressure is under the pendulum disc, this pressure
contributes to the opening of the valve. The flow inlet is under thevalve seat.
If the minimum control pressure is too low for CFB or the permitted medium pressure is exceeded, leaks may occur!

7.2.1

Control functions

Control function A (CFA)
Closed in rest position by spring force.
Control function B (CFB)
Open in rest position by spring force.

▶▶ When opening and closing the device, do not touch themoving pneumatic connection.
▶▶ Do not reach into the area immediately above and below thecontrol air connection.

WARNING!

WARNING!

Risk of injury from damaged devices!

Risk of injury from unsuitable connection hoses!

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 openend wrench, never a pipe wrench.
▶▶ Observe tightening torque (40 ± 3 Nm)

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.

→→ Grease pipe thread before re-installing the actuator(e.g. with Klüber paste UH1 96-402 from Klüber).

8.4.1

Control air connections→→ For control function A: Pressurize control air connection withcompressed air (5.5 bar) so that the pendulum disc is lifted off
the valve seat and is not damaged when screwed in.

The 45° angle connection, which can be orderedseparately, is recommended for the control air
connection!

→→ Screw actuator into the valve housing.

In this case the free-moving hose length should
be min. 250 mm.

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°.

If the hose length is shorter, the durability andfunction of the plug-in coupling will be impaired!
If a straight control air connection is used, thefree-moving hose length should be min. 400 mm.
If the hose length is shorter, the durability andfunction of the plug-in coupling will be impaired!

DANGER!
Risk of injury from high pressure in the system!
▶▶ Before disconnecting lines and valves, turn off the pressureand vent the lines.

Risk of crushing!
▶▶ Due to the risk of crushing, a 90° control air
