Technical Data
Applications:
•
Safety valve prevents excess pressure of gaseous media
in pipelines and vessels. The set pressure is always higher
than the operating pressure. As soon as the pressure is
reached, the valve opens against the force of the spring. The
pressure excess is relieved as soon as the pressure is 10 %
higher than the set pressure.
Features:
•
valve body made from solid bar
•
no dead spaces
•
drainable
•
high-grade inner surfaces
•
no sump, no dome
•
change of seals without special tools
•
safety: closed spring cap
•
optimum cleanability
•
modular assembly systems
•
connections suitable for orbital welding
•
low spare part cost
•
adjustable set pressure
