Product description
Type 2060
5 PRODUCT DESCRIPTION
5.1 Design
The angle seat valve consists of a pneumatically actuated piston
actuator and a 2/2-way valve body. The device uses neutral gases or
air to control the flow rate of liquid or gaseous media such as water,
alcohol, oil, fuel, saline solution, lye, organic solvent or vapour.
The actuator is made of stainless steel.

5.2 Application range
Observe the maximum pressure range on the type label.
• For neutral gases and liquids up to 25 bar (limit: DN65 max. 12 bar).
• Steam up to 230 °C.
• Aggressive media.
5.3 Properties
• High seal tightness due to self-adjusting packing gland.
• High flow rate values due to the stainless steel valve body that
aids in flow.
• Actuator can be seamlessly rotated by 360°.
5.3.1 Options
• Stroke limitation (as max. or min./max. version)
Limitation of the open position of the valve and thus the flow rate
by means of adjusting screw.
• Position feedback sensor
Feedback sensor for the valve position using inductive proximity
switch or Type 8697 feedback sensor
5.3.2 Device variants
The angle seat valve is available for the following actuator sizes:
50, 70, 90, 130 (see “6.4”).

Product description
Type 2060
5.4 Function
Depending on the variant, the valve seat is closed with or against the
medium flow. Spring action (CFA) or pneumatic pilot pressure (CFB and
CFI) generate the closing force on the swivel plate. Force is transmitted
through a spindle connected to the piston actuator.
5.4.1 Control function (CF)
Control function A (CFA)
Closed by spring force in rest position
Control function B (CFB)
Opened by spring force in rest position
Control function I (CFI)
Actuating function via reciprocal
pressurization
5.4.2 Flow under seat
Depending on the variant, the valve is closed against the medium
flow with spring action (CFA) or with control pressure (CFB or CFI).
Operating pressure under the pendulum plate helps open the valve.
WARNING!
Valve seat not sealed when control pressure too low or operating
pressure too high.
If control pressure for control function B and control function I is
too low or operating pressure is too high, this can cause the valve
seat to leak.
▶Comply with minimum control pressure and maximum operating
pressure.
English

9
Technical data
Type 2060
5.4.3 Flow above seat
The valve is closed by spring action (CFA) with the medium flow. The
operating pressure above the swivel plate helps close the valve and
seal the seat. The valve opens through pilot pressure.
WARNING!
Risk of injury from rupturing lines and device with flow
direction above the seat.
In the case of liquid media, a pressure surge can lead to the bursting
of pipes and device.
▶Do not use valves with flow direction above the seat for liquid
media.
In order to ensure complete opening, the minimum pilot
pressure must be used.
6 TECHNICAL DATA
6.1 Conformity
The angle seat valve Type 2060 INOX conforms to EU directives as
per the EU Declaration of Conformity.
6.2 Standards
The applied standards as used to verify compliance with the Directives
can be found in the EU type examination certificate and/or the EU
Declaration of Conformity.

→Replace seal.
WARNING!
Danger due to incorrect lubricants.
Unsuitable lubricant may contaminate the medium. There is a risk of
explosion in oxygen applications.

7.7 Pneumatic connection
WARNING!
Risk of injury due to connecting unsuitable hoses.
▶Only use hoses that can withstand the pressure and temperature
of the medium.
▶Note the technical data provided by the hose manufacturer.
For control function I: Risk of pilot pressure failure.
The valve stays in an undefined position in the event of a pilot
pressure failure.
▶To ensure a controlled restart of the device, apply pilot pressure
and activate the medium.
7.7.1 Connecting the control medium
If the position of the pilot air ports is unfavourable for installing
the hoses, these can be seamlessly aligned by rotating the
actuator by 360°.
The procedure is described in Chapter“7.6” .
Control function A:
→Connect control medium to pilot air port 1.
Control function B:
→Connect control medium to pilot air port 2.
Control function I:
→Connect control medium to pilot air port 1 and2.
Pressure on pilot air port 1 opens the valve.
Pressure on pilot air port 2 closes the valve.
