Non return valves enable a flow in one direction
and block il in the opposite direction.
They therefore belong to the group of check
valves (DIN 24300).
ARGUS non return valves guarantee an
extremely low-resistant flow through their
streamlined internai parts.
The valves are sealed by spring-hydraulic
poppets and washer. Stroke limitation ensures
free outlet opening. Depending on opening
pressure, they can also be used as a suction
and safety valve.
