Typical Manifold Station
ASSEMBLED MANIFOLDS
Valves and manifold stations can be assembled by ROSS to precise specifications.
The assembly is then ready for integration into your system.
For detailed information about such assemblies, consult your ROSS Distributor or call ROSS
in the U.S.A. at 1-888-TEK-ROSS (835-7677) or 1-706-356-3708.
Manifolds for Series W70 & W74 ANSI Valves
The numbers of the manifold stations shown in the chart
below specify pressure ports with NPT threads and electrical
openings with 11/4 NPT threads.
All necessary hardware and seals for manifold assembly are
included with each manifold station.
Indicator Lights: As shown in the chart below, the smaller
sizes of manifolds are available with indicator lights. These
lights are located in the end plate covering the electrical
cavity.
Manifold Note: The port positions of the solenoid controlled
and the pressure controlled manifolds are not the same.
For this reason these stations cannot be mixed in the
same installation. If both types of valves must be used
in the same installation, use only manifold stations for
solenoid controlled valves.
