Assembly

5.1

Installation position

The installation position of flanged gate valves (09320/09420) is arbitrary with respect to the flow. When
installing the flanged gate valve in a horizontal pipeline, we recommend a vertical position of the spindle
(handwheel facing upwards).
The installation position of flanged gate valves with "Guillemin"-outlet is arbitrary with respect to the flow.
When installing the valves in a horizontal pipeline, we recommend a vertical position of the spindle
(handwheel facing upwards).
With regard to the installation position with respect to the flow, pay attention to the flow direction arrow.
When installing the valves in a horizontal pipeline, we recommend a vertical position of the spindle
(handwheel facing upwards).
5.2 Notes regarding the installation

Use suitable tools.

Open-ended spanners

Torque wrench

Clean tools before the installation

Open the packaging only directly before the installation.

Only install the valve if the maximum operating pressure and operating conditions correspond to
the marking on the valve.

Remove protective caps or covers before assembly.

Inspect the valve for dirt and damage.
DO NOT install damaged or dirty valves.

Avoid damaging the connections.
The sealing surfaces must remain clean and intact.

Seal the valve with suitable seals.
No sealant (sealing tape, liquid sealing tape) may enter the valve.
Transformer oil – check suitability.

Connect pipelines in a force-free and torque-free manner.
Stress-free installation.

In order to ensure trouble-free operation, no impermissible static, thermal or dynamic stresses
may be transmitted to the valve. Observe reaction forces.

Temperature-dependent changes in length in the pipework system must be compensated with
expansion joints.

Valves are supported by the pipework system.

The valves must be protected against dirt and damage during construction work.

Check the leak-tightness.
6

Operation


Check the following points prior to start-up:

All assembly and installation work are completed.

The safety guards are in place.

Compare the material, pressure, temperature and installation position with the layout plan for
the pipework system.

Remove any dirt and residues from the pipeline and valve in order to prevent leaks.

Maintenance and service

7.1 Safety during cleaning

Take note of the specifications in the safety data sheet and the general occupational health and
safety rules if degreasers are used for process-related reasons for the cleaning of bearing parts,
fittings and other precision parts.
7.2 Maintenance
The maintenance intervals must be defined by the user according to the operating conditions.
The recommendations for the functional checking of the valves are to be taken from section 7.2.1
"Inspection and maintenance intervals" in these operating instructions.
