Operating and installation instructions
Liquid drainer
1.0 General information on operating instructions
These operating instructions provide information on mounting and maintaining the fittings.
Please contact the supplier or the manufacturer in case of problems which cannot be
solved by reference to the operating instructions.
They are binding on the transport, storage, installation, start-up, operation, maintenance
and repair.
The notes and warnings must be observed and adhered to.
- Handling and all work must be carried out by expert personnel or all activities must be
supervised and checked.
It is the owner’s responsibility to define areas of responsibility and competence and to
monitor the personnel.
- In addition, current regional safety requirements must be applied and observed when
taking the fittings out of service as well as when maintaining and repairing them.
The manufacturer reserves the right to introduce technical modifications at any time.
These Operating Instructions comply with the requirements of EU Directives.
2.0 Notes on possible dangers
2.1 Significance of symbols
ATTENTION !
. . .
Warning of general danger.
2.2 Explanatory notes on safety information
In these Operating and Installation Instructions dangers, risks and items of safety
information are highlighted to attract special attention.
Information marked with the above symbol and “ATTENTION!” describe practices, a failure
to comply with which can result in serious injury or danger of death for users or third parties
or in material damage to the system or the environment. It is vital to comply with these
practices and to monitor compliance.
All other information not specifically emphasised such as transport, installation, operating
and maintenance instructions as well as technical data (in the operating instructions,
product documentation and on the device itself) must also be complied with to the fullest
extent in order to avoid faults which in turn can cause serious injury to persons or damage
to property.
3.0 Storage and transport
ATTENTION !
- Protect against external force (like impact, vibration, etc.).
- Valves must not be used to take external forces, e.g. they are not designed for
use as climbing aids, or as connecting points for lifting gear.
- Suitable materials handling and lifting equipment should be used.
See catalog sheet for weights.
- At -20°C to +65°C.
- The paint is a base coat to protect against corrosion during transportation and storage.
Do not damage paint protection.

Operating and installation instructions
Liquid drainer
4.0 Description
4.1 Scope of applications
Automatic liquid drainers with thermal control are used to drain off condensate during
system start-up and shut-down.
ATTENTION !
- Refer to the data sheet for applications, limits on use and possibilities.
- 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 operator should
state the higher requirements when ordering.
- Valves made from grey cast iron are not authorised for use in systems subject
to TRD 110.
The information complies to the Pressure Equipment Directive 97/23/EC.
It is the responsibility of the machine planner to ensure compliance.
The special markings on the valve must be taken into account.
Refer to the catalogue 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
(refer to Fig. 3 page 6)
The automatic liquid drainer drains condensate from steam facilities during the start-up of a
process. When the set closing pressure is reached the valve shuts automatically.
When the system shuts down or closing pressure is not reached, the valve opens and
automatically takes over residual drainage.
When the system is unpressurised the liquid drainer is held in the open position by the builtin spring (Pos. 24.5). It shuts as soon as the operating pressure has risen to the set closing
pressure (due to the pressure differential effective at the valve area versus spring
resistance).
If the operating pressure drops below the closing pressure it opens due to spring
resistance.
The liquid drainer is supplied as standard with a factory-set closing pressure of ≥ 1,5 bar.
