PRODUCT DESCRIPTION

6STRUCTURE AND FUNCTION

5.1

General description

6.1

Structure

The 2/2-way globe valve Type 2012 is suitable for liquid and gaseous
media. Using neutral gases or air (control media), it controls theflow of water, alcohol, oil, fuel, hydraulic fluid, saline solution, lye,organic solvents and vapour (flow media).
One special characteristic of the globe valves are screwed-in seats,
which can be replaced when needed.

5.1.1

Restrictions
WARNING!

The globe valve consists of a pneumatically actuated piston actuatorand a 2/2-way globe valve body.
The actuator is made from PA. The self-adjusting packing glandguarantees a high degree of tightness. The stainless steel valve
body facilitates high flow values.
Transparent cap
Actuator cover
Actuator housing

Risk of injury from pressure surge.
A pressure surge could cause lines and the device to burst.
Because of the risk of pressure surge, valves with the flow
direction above the seat must not be used for fluid media.
▶ Observe the type of flow and type of medium for operating
the device.

Structure and function

6.2

Function

6.2.2

Depending on the variant, the valve seat is closed in the direction ofor against the medium flow.
Spring force (CFA) or pneumatic pilot pressure (CFB and CFI) generate the closing force on the swivel plate. A spindle connected tothe actuator piston transmits the force.

6.2.1

Depending on the variant, the valve is closed against the medium
flow either with spring force (control function A, CFA) or pilotpressure (control function B or I, CFB or CFI).
Because the medium pressure is below the swivel plate, it helps
open the valve.
WARNING!

Control functions (CF)Valve leak if there is too little minimum pilot pressure or highmedium pressure.

WARNING!
For control function I – risk of pilot pressure failure.
With control function I, the control unit and reset are pneumatic. No defined position is reached during a pressure failure.
▶ To ensure a controlled restart of the device, first apply pilotpressure and then activate the medium.

Technical data

Flow direction above the seat

The valve is closed with the medium flow via spring force (control
function A, CFA). Because the medium pressure is above theswivel plate, it helps the valve close and also contributes tosealing the valve seat.
The valve opens via pilot pressure.
WARNING!
Risk of injury from pressure surge.
A pressure surge could cause lines and the device to burst.
Because of the risk of pressure surge, valves with the flow
direction above the seat must not be used for fluid media.
▶ Observe the type of flow and type of medium for operating
the device.

▶ Observe tightening torques.

Seal

Fig. 6:WARNING!

Dirt trap for devices with approval according to DIN EN 161
According to DIN EN 161 "Automatic shut-off valves for gas burners
and gas appliances", a dirt trap, which prevents the penetration of
a 1 mm test pin, must be installed upstream of the valve.

→ If the approval applies to the valve, such a dirt trap must be
attached in front of the globe valve.

Welded connection:→ Weld or bond valve body in pipeline system.
Other bodies:→ Connect valve body to pipeline.

Seal→ Replace seal.
Risk due to incorrect lubricants.
Unsuitable lubricant may contaminate the medium. There is arisk of explosion in oxygen applications.
▶ Only used accordingly approved lubricants for specificapplications.

→ Before re-installation, grease nipple thread (e.g. using Klüberpaste UH1 96-402 from Klüber).

NOTE!
Damage to the seat seal or seat contour.
▶ The valve must be open before installing the actuator.

→ For control functions A and I, pressurise the lower pilot air portwith compressed air (6 bar).

→ Screw actuator into the valve body. Note tightening torque as
per table 1.

8.7

EnglishHoses that cannot withstand the pressure and temperature
range can cause hazardous situations.
▶ Only use hoses that are permitted for the specified pressure
and temperature range.
▶ Note the data sheet information from the hose
manufacturers.
For control function I – risk of pilot pressure failure.
With control function I, the control unit and reset are pneumatic. No defined position is reached during a pressure failure.
▶ To ensure a controlled restart of the device, first apply pilotpressure and then activate the medium.
If the position of the pilot air ports is unfavourable for
installing the hoses, these can be seamlessly aligned byrotating the actuator by 360° (see chapter “8.6 Turning
