Norgren 4111 User Manual

The Norgren GT Development Rapid Dump Valve is
a pilot-operated, normally open, three-way valve
with two delivery ports. It is intended to be chassis­mounted on heavy duty, on-highway vehicles with air­ride suspensions. Its function is to remotely deflate
the air ride suspension’s air bags. This valve can also
be used to open and close lift and tail gates.

Typical supply pressure is equal to bag pressure (5
–60 PSIG) when Rapid Dump Valve is not actuated and
raises the system pressure (90-120 PSIG) when Rapid
Dump Valve is actuated. Typical pilot pressure is 90­120 PSIG.
