5 Correct use
Ball valves are used to isolate media flows.
Only clean, liquid or gaseous media must be used, and the
body and seal materials used must be resistant to and suit-
able for this. Contaminated media and / or applications out-
side of the pressure and temperature data may lead to dam-
age to the body and, in particular, to the seals on the ball
valve.
The "Technical data" chapter describes the permissible pres-
sure / temperature range for these ball valves.
Danger of explosion!
▶ Risk of severe injury or death.
Do not use the product in potentially
●
explosive zones.
Only use the product in potentially ex-
●
plosive zones confirmed in the declara-
tion of conformity.
Improper use of the product!
▶ Risk of severe injury or death
▶ Manufacturer liability and guarantee will be void
Only use the product in accordance with the operating
●
conditions specified in the contract documentation and in
this document.
The product is designed for installation in piping systems and
for controlling a working medium.
1. Use the product in accordance with the technical data.
2. Note the supplement acc. to ATEX
Due to the design, in the open and closed position, a low
volume of medium may be trapped within the ball or between
the ball and the body.
Expansion of the medium due to temperature differences,
change in state or a chemical response may lead to a high
pressure build-up. In order to prevent unacceptable pressure
increases, a special version with pressure-relief hole in the
ball is available on request for this case.
Build-up of lint!
▶ For soft-seated ball valves, due to the relative rotations of
the stainless steel ball valve to the seat seal, slight wear
of the PTFE seals must always be anticipated. Despite
this, the safety of the ball valve is not affected by any po-
tential build-up of lint and the seal materials are compli-
ant in accordance with FDA directives.
