3 BASIC SAFETY
INSTRUCTIONS
These safety instructions do not consider any contingencies or inci-
dents which occur during installation, operation and maintenance.
The operator is responsible for observing the location-specific safety
regulations, also with reference to the personnel.
Danger – high pressure.
▶Before dismounting the lines and valves, turn off the pressure
and vent the lines.
Risk of electric shock.
▶Before reaching into the device, switch off the power supply

Product description
5 PRODUCT DESCRIPTION
5.1 General description
The angle seat valve Type 2100 is suitable for liquid and gaseous
media. It uses neutral gases or air (control media) to control the flow
of water, alcohol, oil, fuel, hydraulic fluid, saline solution, lye, organic
solvent and steam (flow media).
5.2 Versions
There are 2 versions of the angle seat valve type 2100:
• Standard version without separate Ex type label.
The standard version must not be used in the potentially explosive
area.
• Ex version with separate Ex type label.
The Ex version may be used in the potentially explosive area. In
doing so, observe the specifications on the separate Ex type label
and the additional information enclosed with the device together
with safety instructions for the Ex area.
5.3 Properties
• High tightness by self-adjusting packing glands.
• High seat tightness by swivel plate.
• High flow values by the streamlined valve body made of stainless
steel.

6 STRUCTURE AND FUNCTION
6.1 Structure
The angle seat valve consists of a pneumatically actuated piston
actuator and a 2/2-way valve body. The actuator is manufactured from
polyphenylene sulphide (PPS).

6.2 Function
6.2.1 Control function 2/2-way valve
Spring force (CFA) or pneumatic pilot pressure (CFB and CFI) gen-
erates the closing force on the swivel plate. The force is transferred
via a spindle which is connected to the actuator piston.

2(A)
WARNING!
For control function I – Danger if pilot 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
pilot pressure, then switch on the medium.
6.2.2 Control function 2/3-way valve
Type 2100 with 3-position actuator is available in control function A
(CFA) only.
Control function A (CFA)
Normally closed by spring action
The spindle, which is connected to the actuator piston, transfers the
closing force to the swivel plate. Pressurization of the pilot air port 2
moves the upper movable group axially downwards until the preset
center position has been reached. Pressurization of the pilot air port 1
moves the lower movable group axially upwards until it hits the upper
piston and stops. This center position corresponds to a specific
adjustable flow rate of the medium. If the upper air chamber is vented
by pilot air port 2, both modules move upwards and the maximum stroke
is reached. If the lower air chamber is vented by pilot air port 1, the
spring force acts on the lower movable group and therefore moves it
downwards until the valve is closed (rest position).

Structure and function
6.2.4 Flow direction below seat
Depending on the version, the valve is closed against the medium
flow with spring action (control function A, CFA) or with pilot
pressure (control function B or I, CFB or CFI).
As the medium pressure is under the swivel plate, this pressure
contributes to the opening of the valve.
WARNING!
Medium may be discharged if minimum pilot pressure is too
low or medium pressure too high.
If the minimum pilot pressure is too low for CFB and CFI or the
permitted medium pressure is exceeded, leaks may occur.
▶Observe minimum pilot pressure
▶Do not exceed medium pressure.
CFA CFB /
CFI
Fig. 4: Flow direction below the seat
(Rest open/closed, closing against medium)
6.2.5 Flow direction above the 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 pilot pressure.
WARNING!
Risk of injury from water hammer.
A water hammer could crack the lines and device.
Due to the risk of water hammer, valves with a flow direction
above the seat must not be used for liquid media.
▶Consider the type of flow direction and the type of medium for
operation of the device.
To ensure complete opening, the minimum pilot pressure
must be used.
