Manifolds for Series W70 & W74 ANSI Valves
A

C
The numbers of the manifold stations shown in the chart
below specify pressure ports with NPT threads and electrical
openings with 1¼ 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.

Accessories
Interposed Pressure Regulators
Both single and double interposed regulators are available
for valves with CV ratings up to 4.2. A regulator is bolted to
the valve’s sub-base or manifold station, and the valve is
then bolted to the regulator. This mounting method allows
the valve to be removed and replaced without disturbing the
regulator.
Single pressure regulators provide the same regulated
pressure at both outlet ports. Double pressure regulators allow
the pressure at each outlet port to be set independently.
A locking type knob is used to set the regulated pressure at
any point in the range of:
5 to 100 psig (0.3 to 7 bar) for size 1 and 2 models;
5 to 125 psig (0.3 to 8.5 bar) for size = 4.2 models.
Maximum inlet pressure is 150 psig (10 bar).
Pressure gauge(s) included.
Order regulators by the part numbers shown at the right.

the 14 solenoid will pressurize the 2 port - which may

Manual Override Kits for Solenoid Pilot Controlled Valves
FLUSH BUTTON
Locking type ............... Kit 792K87
Flush flexible manual overrides are standard on solenoid pilot
controlled valves with CV ratings of 2.0 or larger. Both locking
and non-locking metal override buttons are also available for
these models.
Each of the override buttons in the kits at the right is made
of metal and is spring-returned. The locking type button,
however, can be kept in the actuated position by turning the
slot in the top of the button with a screwdriver.
Order by the kit numbers shown at the right.
