4.0 Description
4.1 Area of application
Valves are used for „controlling the flow of liquids, gases and vapours in chemical and other
processing plants and for plant engineering“.
It is the responsibility of the machine planner / owner to ensure compliance.
The special markings on the valve must be taken into account.
Refer to the technical data sheet to see which materials are used in standard versions.
Please contact the supplier or the manufacturer if you have any questions.
4.2 Operating principles
The valve is closed by turning the actuator stem.
The stem moves through 90°.
The position of the segmented ball can be determined from the mark on the shaft end face
when the actuator is dismantled (marking groove points in the direction of the control open-
ing).
ATTENTION !
- Refer to the technical data sheet for applications, limits on use and possibilities.
In particular, you must check the material stability.
- Certain media require or preclude the use of special materials.
- The valves are designed for standard operating conditions. If conditions exceed
these requirements, e.g. aggressive or abrasive media, the owner should state
the higher requirements when ordering.
- Careful selection and sizing of the valve based on the anticipated operating
conditions is essential for low-noise, low-vibration operation.
- You must state whether the valves are to be used in explosive atmosphere
(ATEX) when ordering.
(Special version owing to the marking / design)
- As a general rule, we recommend that you do not install valves immediately
downstream from pipe bends or tees. Particularly with control applications, you
should allow a section equivalent to at least 2 x DN before and 6 x DN after the
valve in accordance with DIN EN 60534.
ATTENTION !
- The actuator stem is partially open and there is a crushing hazard

5.0 Installation
5.1 General remarks on installation
The following points should be taken into account in addition to the general principles gov-
erning installation work:
ATTENTION !
- Remove flange covers if present.
- Connection flanges must mate exactly.
- Clean the pipework carefully before installing the valve. The interior of the valve
and the pipeline must be free of foreign particles, as these could damage the
valve’s shut-off surfaces.
- The installation position should be selected so that the flow approaches the
valve from the segmented ball side. The maximum differential pressure must be
observed (see technical data sheet).
- Steam line systems should be designed to prevent water accumulation.
- Install pipelines so that damaging transverse, bending and torsional forces are
avoided.
- Do not install the valve close to a pump or a curved pipe section due to the
turbulent flow that they cause. There must be as little turbulence as possible in
the flow at the valve.
- The pipes must be provided with appropriate support. An inadequately
supported section of pipework will cause excessive stress on the valve,
possibly resulting in leakage from the shut-off surfaces.
- Pipework temperature variations will cause thermal contractions and
expansions which must be allowed to occur freely, for example with the aid of
bellows expansion joints. Without these or other similar solutions, pipework
expansions will excessively burden the joints.
- Protect valves from dirt during construction work.
- Valve mountings such as actuators, handwheels, hoods must not be used to
take external forces, e.g. they are not designed for use as climbing aids or as
attachment points for lifting gear.
- Flooding of the valve is not permissible.
- Suitable materials handling and lifting equipment should be used for assembly
work. During assembly work, ensure that the valve is fixed adequately.
See technical data sheet for weights.
- The preferred installation position relative to the stem direction is horizontal.
- The unmounted valve may only be operated if all safety precautions are
observed. Crushing hazard!
- When installed vertically, large actuators must be supported.
- Avoid mechanical damage to the seat during transport, storage and installation.
- Protect actuators from excessive ambient temperatures; refer to the operating
instructions for the actuators.
- With actuators mounted, you must disconnect the power supply before starting
work.
- The valve should be installed in the open position.

Operating and Installation Instructions
PALTRA®-V
- Planners / construction companies or the owner are responsible for positioning and
installing products.
- The valves are designed for deployment in systems that are not affected by the weather.
- For applications outdoors or in adverse conditions like corrosive environments (seawater,
chemical vapours, etc.), special designs or protective measures are recommended.
- The valves are not approved for subsurface installation.
5.2 Installing wafer type valves (Fig. 501)
- Please check the type of neck-welded flange in the Production Card.
- Make sure that mounting shims totally cover contact surfaces.
- During installation make sure that flanges and shims are coaxial and parallel to each
other.
- The segmented ball must be in the closed position during installation.
- Check that there are no obstructions inside the valve before installation.
Installation order.:
Preassemble the unit comprised of the valve, mounting shims and flanges. Secure it using
a few of the bolts but tighten them only slightly.
Tack-weld the preassembled unit to the pipeline.
Remove the valve and the mounting shims from the pipeline, then weld the flanges all
around the perimeter.
Insert the valve and tighten the stud bolts evenly in crosswise sequence.
ATTENTION !
- The sealing element (25 and possibly also 15/16) between the counter flange and
the body (Fig. 7 + Fig. 8) is pressed tightly via the bolts of the flanges. This must
be taken into account when determining the bolt tightening torques required for
operational tightness.

PALTRA®-V
5.3 Installing flanged valves (Fig. 502)
- Preassemble the unit comprised of the valve, flanges and flange gaskets using between 4
and 6 studs. Be careful not to tighten the studs too tight on the nuts.
- Make sure that all parts are coaxial and parallel to each other.
- Assemble and tighten the valve with the remaining fasteners.
- After installing the valve, make sure that it will not be under excessive stress and that the
flanges are parallel and coaxial to each other. The valve may only be pressurised after the
flanges have been completely installed. Incorrect installation could result in leakage or
damage to the sealing elements.
5.4 Installing additional modules and piping elements
Optional accessories (limit switches, etc.) that are supplied with valves must be fitted as
required for their functions as shown in the system plan.
If piping elements are supplied with the product by the manufacturer or enclosed with the
valves, the system owner must ensure that they are operated safely under reasonably fore-
seeable conditions and in compliance with limit values. Protective measures must be imple-
mented based on a hazard analysis in accordance with DIN EN 16668:2016, 5.1.3
“Protection against exceeding the allowable limits”. If the nature or conditions of the
intended use, including all foreseeable circumstances, are such that protective measures
are necessary (e.g. to prevent inadmissible pressure increases), the manufacturer should
be notified immediately. The system owner is thus personally responsible for ensuring
operational safety.
5.5 Requirements at the place of installation
The place of installation should be easily accessible and provide ample space for mainte-
nance as well as for removing the actuators. The valve should preferably be installed hori-
zontally with the actuator at the side. Inclined or horizontal installation without supports is
only permissible with lightweight actuators.
Permissible actuator weights for unsupported valves installed horizontally relative to the
stem:
35 kg for DN 80 - 100
40 kg for DN 125 - 150
55 kg for DN 200 - 250
65 kg for DN 300
The pipes must be lagged to protect the actuators from excessive heat. Sufficient space
must be allowed for maintaining the stem seal.
5.6 Installation requirements for setting up and dismantling actuators
Normally, valves are supplied complete with the actuator fitted. It is not permitted to set up
or dismantle actuators with valves operating at the service temperature and pressure. The
actuators must be installed as described in the operating instructions for conversion or
maintenance.
When connecting the electric actuators, you must comply with the specifications of the Low
Voltage Directive. Connection (grounding) of electric actuators must only be carried out by
qualified personnel.
