Product description
Type 2012
5 PRODUCT DESCRIPTION
5.1 General description
The 2/2-way globe valve Type 2012 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).
A particular feature of the globe valves are screwed in seats which can
be changed if required.
Definition of DN
DN designates the nominal width of the seat, not the
nominal width of the line connection.
5.1.1 Restrictions
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 seat must
not be used for liquid media.
▶Consider the type of flow direction and the type of medium for
operation of the device.
6 STRUCTURE AND OPERATING
MODE
6.1 Structure
The globe valve consists of a pneumatically actuated piston actuator
and a 2/2-way globe valve body.
The actuator is manufactured from PA or, for special operating con-
ditions, from PPS. The self-adjusting packing gland ensures a high
degree of tightness. The valve body, made of stainless steel, enables
high flow values.

Structure and operating mode
Type 2012
6.2 Operating mode
Depending on the version, the seat of the valve is closed with or against
the medium flow.
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.
6.2.1 Control functions (CF)
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 pressurise the device with pilot
pressure, then switch on the medium.

6.2.2 Flow direction below seat
Depending on the version, the valve is closed against the medium
flow with spring force (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 con-
tributes 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.
▶See chapter entitled “7.4.2”.

Technical Data
Type 2012
6.2.3 Flow direction 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 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 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 applied.

8.3 Installation
WARNING!
Risk of injury from improper installation.
Installation 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 torques (see “Tab. 1: Tightening torques
of valve body / nipples”).
Dirt trap for devices with authorization in accordance with DIN
EN 161
In accordance with DIN EN 161 “Automatic shut-off valves for gas
burners and gas appliances” a dirt trap must be connected upstream
of the valve and prevent the insertion of a 1 mm plug gauge.
→If the authorisation also applies to stainless steel bodies, the same
type of dirt trap must be attached in front of the globe valve.

8.3.3 Rotating the actuator
The position of the connections can be aligned steplessly by rotating
the actuator through 360°.
NOTE!
Damage to the seat seal or the seat contour.
▶When rotating the actuator, ensure that the valve is in open
position.
Procedure:
→Clamp the valve body in a holding device
(applies only to valves which have not yet been installed).
→Control function A and I: pressurize the lower control air con-
nection with compressed air (6 bar): valve opens.
→Counter on the flats of the nipple with a suitable open-end wrench.
WARNING!
Risk of injury from discharge of medium and pressure.
If the direction of rotation is wrong, the body interface may become
detached.
▶Rotate the actuator module in the specified direction only.

Installation
Type 2012
→Loosen screw above the nipple by a half turn and turn it clockwise
(as seen from above) to move the actuator to the required position.
→Retighten screw (Tightening torque 100 ± 5 Nm).
8.4 Pneumatic connection
DANGER!
Danger – high pressure in the equipment.
▶Before loosening the 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 authorised for the indicated pressure
and temperature range.
▶Observe the data sheet specifications from the hose manufacturers.
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.
If the position of the pilot air ports for installation of the hoses
is unfavorable, these can be aligned steplessly by rotating
the actuator through 360°.
Control function A
→Connect the control medium to the lower control air connection
of the actuator.
Control function B
→Connect the control medium to the upper control air connection
of the actuator.
Control function I
→Connect the control medium to the lower and upper control air
connection of the actuator.
If used in an aggressive environment, we recommend con-
veying all free pneumatic connections into a neutral atmo-
sphere with the aid of a pneumatic hose.
Control air hose:
6 mm, 4 mm or 1/4” control air hoses can be used.
