The diagram shows a poppet made of stainless steel. In
contrast to balls, poppets offer lower wear and prevent
chatter. An exact guide for the poppet and spring en-
sures function stability.
Ordering code
Manatrol check valves of the series C for pipeline instal-
lation provide free flow in one direction and block flow in
the counter-direction. Depending on material speci-
fication, these valves are suited for use in hydraulic and
pneumatic systems.
Specific Manatrol poppets and poppet guides ensure re-
liable functional integrity even at high flow rates and/or
pulsations.
