Both single and double interposed regulators are available
for valves with C
V
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.
Interposed Pressure Regulators
Flush flexible manual overrides are standard on solenoid pilot
controlled valves with C
V
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.

WARNING
Double interposed regulators will reverse output
ports - the 12 solenoid will pressurize the 4 port,
the 14 solenoid will pressurize the 2 port - which may
cause unexpected, potentially dangerous cylinder
movement at valve pressurization.
