2 Safety
2.1 Intended use
The angle valve is intended for mounting in a pipeline or pressure tank system in order to block media or
allow them to pass through within the permissible operating conditions. The permissible operating
conditions are specified in these operating instructions.
The angle valve is suitable for the media listed in these operating instructions; see section 4.5 "Media".
Operating conditions and applications deviating from these require the approval of the manufacturer.
Only media may be employed to which the materials used for the valve body and seals are resistant.
Contaminated media or usage outside of the pressure and temperature specifications can lead to damage
to the valve body and seals.
Avoidance of foreseeable incorrect use
Never exceed the permissible usage limits specified in the data sheet or in the documentation
with regard to pressure, temperature, etc.
Follow all safety instructions and operating procedures in these operating instructions.
2.2 Meaning of the operating instructions
The operating instructions are to be read and followed by the responsible technical personnel before
mounting and start-up. As part of the angle valve the operating instructions must be available close to it.
People could be seriously injured or killed if the operating instructions are not followed.
Read and observe the operating instructions before using the angle valve.
Retain the operating instructions and make sure they are available.
Pass on the operating instructions to subsequent users.

4.3 Intended use
Angle valves are used for shutting off and/or throttling media.
Install angle valves so that the stem is vertical and the type of the
medium enters under the cone.
The angle valve is opened or closed by turning the handwheel or
actuating the actuator. Tools for increasing handwheel torque are
not allowed.
Detailed installation instructions for the actuator are included for
angle valves with pneumatic or electric actuator-unit.

4.9 Lifetime
The user is obligated to use Herose products only for their intended purpose.
In this case, a technical service life may be assumed in accordance with the underlying product standards
(e.g. EN1626 for shut-off valves and EN ISO 4126-1 for safety valves).
The technical service life can be restarted several times through the exchange of wearing parts within the
context of the maintenance intervals, and lifetimes of more than 10 years can be achieved.
If products are stored for a period exceeding 3 years, then the plastic components and elastomer sealing
elements fitted to the product should be replaced as a precautionary measure before mounting and use.
