3.2 Intended use
These valves are used for the separation of measuring instruments from
the process by means of shut-o, venting and pressure compensating
function(s) They are designed for use in applications with clean gaseous
and liquid media that are not highly viscous or crystallising.
The product must only be used with media which are not harmful to
the wetted parts over the entire operating range of the instrument. Any
change in the state of the matter or any decomposition of unstable media
is not permitted.
Only use the product in applications that lie within its technical performance limits (e.g. max. ambient temperature, material compatibility, ...).
→ For performance limits see chapter 9 “Specications”.
Improper handling or operation of the product outside of its technical
specifications requires the instrument to be taken out of service
immediately and inspected by an authorised service engineer.
These valves do not have their own potential ignition source. The
responsibility for the safe use in hazardous areas in accordance with
the accepted standards of technology rests with the operator.
For the reasons mentioned above, these valves are not marked and do
not have their own certification.
The product has been designed and built solely for the intended use
described here, and may only be used accordingly.
The manufacturer shall not be liable for claims of any type based on
operation contrary to the intended use.
EN
3.3 Improper use
Improper use is dened as any application that exceeds the technical

5. Commissioning, operation
WARNING!
Physical injuries and damage to property and the
environment caused by media escaping under high
pressure
With the pressurisation of the product, as a result of poor
sealing of the connections, media under high pressure can
escape.
Due to the high energy of the media that can escape in
the event of a failure, the possibility of physical injuries and
damage to property exists.
▶
The sealing of the connections must be carried out expertly
and checked for leak tightness.
WARNING!
Physical injuries and damage to property and the
environment caused by improper handling.
Incorrect opening or closing of a valve can lead to the
escape of media.
▶
The operator must be aware of the consequences prior to
changing the state to a specic valve position.
5.1 Mounting
■
When unpacking, check all components for any external damage.
If a return is needed, please follow the instructions given in chapter
8.2 “Return”.
■
Ensure that all unused connections are closed. Plug screws for vent
connections are included in delivery, though not pre-tted.
■
The valve may only be carried by the valve body, not by the handle
■
Check the product marking for correctness (see chapter 3.7 “Labelling, safety marks”).
■
Before mounting, ensure that the process line has been depressurised using the main valve.
■
Mount the measuring instrument at the right connection. Ensure that
the ow direction arrow points from the process connection towards
the measuring instrument.

5. Commissioning, operation
■
Remove the protection caps of the required process connections.
■
Ensure that the sealing faces are clean and do not show any mechanical damage.
■
The correct sealing element must be used for the respective
EN
connection.
Threaded connection
To screw in threaded connections the appropriate tool must only be
applied through the spanner ats provided for this purpose.
The tightening torque is dependent on the process connection and
sealing element used.
Flange connection
Applicable models: IV20, IV21, IV30, IV31, IV50, IV51
Use only the bolts and sealing rings included in delivery:
Models IV20, IV21: 2 bolts, 1 sealing ring
Models IV30, IV31, IV50, IV51: 4 bolts, 2 sealing rings
Instructions for correct process connection mounting can be
found in the relevant standards e.g. IEC 61518
1. Fix the instrument for valve mounting on the workbench.
2. Apply a small amount of grease on the bolts.
3. Apply a small amount of grease to each sealing ring to hold it in
place.
4. Position the valve manifold on the instrument.
5. To ease the mounting for ange connections with 4 screws, place
two centring pins opposite each other.
6. Screw in 2 bolts and tighten them by hand.
7. If applicable, remove the centring pins used before.
8. Then screw in the other 2 bolts and tighten them by hand.
9. Use the torque spanner and tighten the bolts opposite each other
with an initial torque of 34 Nm.
10. Use the torque spanner and tighten the bolts opposite each other
with the nal torque depending on the material.
Final torque for stainless steel: 72 Nm.
Final torque for carbon steel: 87 Nm.

5. Commissioning, operation
5.2 Commissioning and operation
To close the valve, turn the handle in a clockwise direction as far as the
stop. To open the valve, turn the handle anticlockwise as far as the stop.
It will take approximately 4 turns from open to closed and vice versa.
The ow can be controlled by not totally opening/closing the valve.
Please note that the handle may present a slight play and
spin freely up to a quarter turn when in the depressurised
state. This is due to the constructive design.
■
The valve, especially the handle, must not be subjected to any external loading (e.g. use as a climbing aid, support for objects).
■
The handle may only be used by hand; the use of tools is not
accepted.
■
The torque on reaching the valve stop must only be hand-tight.
■
Ensure that all valves of the product are closed prior to opening the
main valve of the process line.

7.1 Maintenance
When used properly, the valves work maintenance-free. They must be
checked within the context of regular maintenance.
Inspection interval
Depending on the process, the ambient conditions and the number of
operations, the required inspection interval may vary from daily to several
weeks.
Recommended inspection interval: ≤ 3 months
Inspection checklist
1. Leak test of the process and instrument connections
2. Leak test between bonnet and valve body
3. Functional test for correct opening and closing
In case the leak test of item 2 fails, proceed with the adjustment of the
sealing packing described below.
7.2 Repair
Adjustment of the sealing packing
This adjustment is required when a leak can be detected at the valve
spindle, directly below the handle, or when during operation there is no
torque or resistance when turning the handle.
1. Loosen the counter nut
2. Increase the packing compression through the gland nut applying a
torque of ≥13 … ≤ 18 Nm (18 … 25 lbs ft)
3. Fix the gland nut with the counter nut
EN
If after the adjustment of the sealing packing the leakage problem
persists, the packing must be returned for repair.
Perfect functioning of the product can only be guaranteed
when original accessories and spare parts are used.
