Operating instructions BA 26l-02_EN
0. Introduction
These instructions are designed to assist the user during installation, operation and maintenance of multi-port ball valves from
the
BR 26l
,
BR 26t
,
BR 26v
and
BR 26x
.
Note
The WARNING and CAUTION notes must be strictly adhered to. Otherwise this may lead to personal injury and
equipment damage and the manufacturer’s warranty may become void.
Please contact the manufacturer if you have any queries, see section 8 for contact address.
1. Intended use
After installing the valve in the pipeline and connecting the actuator to the control equipment, these ball valves are designed
exclusively for use within the permissible pressure and temperature ranges. The valves are used to shut off, divert, divide the
flow or to mix two flows.
The permissible pressure and temperature ranges for these ball valves are specified in the data sheets <
TB26l
>.
Danger
Do not operate a ball valve when its permissible pressure/temperature rating is not sized for the operating
conditions specified in the data sheets <
TB26l
>.
Failure to follow these safety precautions may result in personal injury and can damage equipment
installed in the pipeline.
Observation of conformity with the Directive 2014/34/EU.
Note
Pfeiffer valves do not have their own potential ignition source according to the risk assessment in the rare incident
of an operating fault in accordance with DIN EN 13463-1 and therefore do not fall within the scope of the Directive
2014/34/EU. Relating to this directive, CE marking is not permissible.
The valve could be incorporated into potential compensation of plants independent of the directive, valid for
metallic parts in hazardous areas.
The ball valve body may contain small amounts of medium in the closed and open position:
In the case that the heat in the surroundings where the valve is installed can heat up the process medium in the valve, use
the ball valve version with a relief bore to prevent an impermissible rise in pressure.
Parts subject to wear are not covered by the warranty.
Observance of section 2 <Safety instructions> is presumed for the Intended use.
2. Safety instructions
2.1
General safety instructions
For ball valves, the same safety regulations apply as for the pipelines in which they are installed. These instructions only specify
those safety instructions which need to be additionally observed concerning ball valves.
2.2
Safety instructions for the operator
The manufacturer does not assume any responsibility. Therefore, on using the ball valve, make sure the following instructions
are observed:
The valve is to be used only for its intended use as described in section 1.
