Assembly and disassemblyInstall the control valves into the pipeline and connect them to the lines for the air supply and control signal observing the acceptedindustry codes and practices.
For installing the valve into the pipeline we recommend a minimal distance of “a” nominal valve size (a x DN) in front of the valve
and “b” nominal valve size (b x DN) behind the valve.

Make sure that the valves are mounted stress-free in the pipeline.
An insufficient cross-section of the supply air line or an insufficient supply pressure impair the valves' control response or proper
functioning. An excessive supply pressure can damage the actuator and accessories.
Shut off, drain and vent the respective pipe section according to the operator's instructions before installing or removing the valves.
Pressure-test the pipeline before installing the valves.
Make sure the pipeline is free of any residue (e.g. weld spatter, metal chips, tools etc.). Remove any foreign particles. Make surethe valves are mounted free of stress and not exposed to excessive vibration.
If the actuators require support in the pipeline, observe the permissible locations. The permissible locations and weights for support
are detailed in the VETEC regulations. Do not use the piping and control equipment as support or to suspend valves duringtransport; do not step on the piping and control equipment to prevent damage.
Subject all valves taken from stock to safety, functional and leak tests before use.
Failure to follow the instructions properly can lead to malfunctions and pose a considerable danger to persons, goods and theenvironment.
Operation
The control valves, as parts of the plant, are to be operated according to the operator's instructions and regulations. Unstable
control causes increased wear. Contaminated supply air (e.g. with oil, water, dirt) or auxiliary energy and signals not according to
specifications can cause the accessories or the entire control valve to malfunction or fail. Protect the valves against impermissible
internal or external stress during operation.
The operator must make sure that the valves' permissible pressure and temperature limits are not exceeded due to a thermal
expansion of the process medium.
Wear and corrosion may make it necessary to check the wall thickness of the valve bodies at regular intervals. The minimum
required wall thickness is calculated and specified by VETEC.
The valves must be checked for their function at regular intervals (1 x monthly). Perform at least one complete switching cycle.

Page 2 of 13Service and maintenance
The valves do not require maintenance. However, they are subject to natural wear, whose extent depends on the operatingconditions. Wear can be identified by an impaired shut-off, increased external leakage, deteriorating control quality or unusual
noise emissions.
When repairing or replacing parts subject to wear on disassembled valves in the workshop, proceed as described in the mounting
and operating instructions. Only use original spare parts by VETEC Ventiltechnik GmbH.
As the valves may contain residue of the process medium, we recommend to remove the valves from the pipeline observing themedium-specific safety instructions.
Depending on the field of application, allow the valves to cool down or heat up to reach ambient temperature before starting anywork on them.
Before starting any work on the valves or actuators, shut off the pneumatic and electric supplies to prevent any hazards caused bymoving parts of the valves or actuators. In particular, make sure that the actuator springs remain compressed even after theactuators have been vented and the supply has been shut off. This is particularly important to remember when removing theactuators from the valves or when opening the actuators.
When changing or retrofitting packing systems, e.g. according to TA-Luft, observe the VETEC mounting instructions.
When mounting pressure-bearing parts on the valves, observe the tightening torques for bolts and screw connections specified in
the maintenance instructions.
Marking
The valves have a nameplate. The nameplate is attached to the actuator or, for deliveries without actuator, to the valve'sconnecting flange.
Conformity with the European Pressure Equipment Directive 2014/68/EU is documented by the CE marking on the nameplates.
Exception: valves according to 2014/68/EU, Article 4, Paragraph 3 (good engineering practice).
The valve and actuator types, nominal size, nominal pressure, serial number, order number etc. are specified on the nameplate.

Transport for mounting
Use only the predefined locations to suspend
the control valves during transport. Whendamaged, it can no longer be guaranteed thatthe valve moves to its fail-safe position(transit time). Use only the predefined
locations to suspend the control valves duringtransport. Control lines, accessories as wellas other components with fail-safe function
must not be used as suspensions fortransport.

Accessories and control line
As DVGW valves are safety valves, allcontrollines,
accessories
andcomponents for fail-safe function must
be protected against improper use.
When damaged, it can no longer beguaranteed that the valve moves to its
fail-safe position (transit time). Any
structural changes to the DVGW valvesdelivered by VETEC must be performedby trained personnel.

FMake sure no improper
forces act on the control lineor accessories. Do not store
the valve on the control line
since this can cause
damage.

FF

Do not step on thecontrol line oraccessories and do
not damage themwith tools.

FInsulating the pipeline and control valve
Insulate the valve so that neither the fail-safe action nor the proper functioning are impaired.

Insulating valves with TA-Luft packing
Make sure no excessive temperatures or heat accumulation occur at the packing or seal. The recommended values given in the table are to beobserved.
Valves with TA-Luft packing are marked specially.

Starting up valves with longer heating-up time
For valves in sizes DN 200 or larger and for operating temperatures above 200 °C, expansion of the components due to heat cannot be avoided.
Since the components are made of different materials, the degree and direction of heat-induced expansion, due to the design, are not exactlydefined.

due to heat exposure.

During the heating-up period, the heat is distributed rather unevenly across thevalve. The components expand differently. As a result, the plug can get jammedin the seat ring (see drawing).

As a result, open the valve slightly (angle of approx. 2° to 3°) before start-up andclose it again after start-up when the process medium has distributed the heatevenly (see drawing).
.

2° bis 3°The valve can be opened by the specified angle using the actuator or additionallymounted travel stops on the actuator.
