Function
Normally-Open Condition (not actuated)
The Rapid Dump Valve shall not leak in excess of 10 SCCM with any pressure from zero to 120 PSIG
applied to supply (SUP) port and delivery ports blocked when pilot port is open to atmosphere.
Pilot Condition (actuated)
The Rapid Dump Valve shall not leak in excess of 50 SCCM with any pressure from 80 to 120 PSIG applied
to pilot port.
The Rapid Dump Valve shall not leak in excess of 50 SCCM with any pressure from zero to 120 PSIG
applied to supply port and delivery ports open.
Proof Pressure
300 PSIG pressure applied for 10 seconds to supply port with delivery ports blocked and pilot port open
to atmosphere.
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 chassis-
mounted on heavy duty, on-highway vehicles with air-
ride 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 90-
120 PSIG.
Our policy is one of continued research and development. We therefore reserve the right to amend,
without notice, the specifications given in this document.
