A quick release coupling
is squirt-free if during connection the coupling and adaptor are already
sealed against each other before valves open (see picture).
Most quick release
couplings on the market are not squirt-free. Others are conditionally squirt-free
which do not "squirt" with fluid pressure on one side only.
Walther squirt-free couplings offer more operating comfort, greater safety
and improved environment-friendliness.
E.g. this means customer benefits as follows:
- lower environmental
pollution due to less fluid spillage independent of the disconnection speed.
Because the coupling is squirt-free, it has only a quantifiable leakage
which is already so low with the smaller bore couplings that you can eliminate
the need for clean-break valves in many cases.
- less danger with
aggressive fluids (e.g. steam, hot gases and liquids, corroding liquids
etc.) and fewer concerns caused by escaping gases/odours.
- no squirting of
pressurized fluids during connection and disconnection.
- no expansion noise
during connection and negligable expansion noise during disconnection.
- very little separation
force during disconnection.
Quick couplings of LP-series, nominal bore sizes 6 mm up to 19 mm, are
squirt-free to standard.
