Operation
After correct installation and taking all necessary safety precautions, the FLOW-CONTROL is ready to be used.
3.1
First use
Before using the FLOW-CONTROL with corrosive, reactive or explosive media, purging for at least 30 minutes with a dry,
inert gas (like Nitrogen or Argon) is strongly recommended. After use with these media, purging is also recommended,
before exposing the instrument to air.
3.2
Points of attention
Check the system for leaks before applying pressure, especially if toxic, explosive or other dangerous fluids are used.
Be sure to apply the specified operating pressure(s). Avoid pressure shocks and bring the fluidic system gradually up to the
level of operating conditions; open and close the fluid supply gently.
Do not pressurize the instrument beyond the maximum working pressure, stated on the instrument label.
When closing the valve, do not tighten the control knob with excessive force.This might damage the sealing surface of the
needle valve, which seriously reduces performance. The needle might even get jammed in the valve seat, blocking the flow
permanently.
