4-way Valve (Double-acting Actuators)
When operator is energized, the spool shifts, driving the
actuator CCW. When de-energized the spool returns,
driving the actuator CW. For de-energized CCW, rotate
directional valve 180°, so that operator points left.
Temperature: NEMA 4X: -20°F to 150°F
NEMA 4X, 7 & 9: -20°F to 125°F
For temperatures below 40°F, air must
be free of water vapor.
Pressure: Minimum: 35 psig
Maximum: 150 psig
Media: Dry or lubricated non-corrosive gas
compatible with nitrile seals.

3-way Valve (Spring Return Actuators)
When operator is energized, the spool shifts allowing
the air pressure to enter the actuator and compress the
springs. When de-energized, the spool returns,
exhausting the air.
• Coil is U.L. and C.S.A. recognized
• Standard 1/2" NPT connector meets
NEMA 4X rating

Solenoid Electrical Characteristics
Characteristics for standard coils are shown below.
All common voltages and hertz are available.
Weatherproof intrinsically-safe/low power
A .67 watt coil is available with 1/2" NPT weatherproof
housing. The operator has Factory Mutual Entity approval.
See the separate I.S. operator I.O.M. for further information.
The Automax NAMUR Directional valve mounts
directly to SuperNova series actuators which
eliminates the cost of tubing and fittings. The valves
are available for double acting and spring return
actuators with NEMA 4, 4X, 7 & 9, weatherproof
intrinsically-safe, and low power solenoid operators.
These valves have been tested and proven reliable
for over 1 million cycles.
Options:
Dual coil 2-position and 3-position valves are available.
Consult factory.
Sandwich NAMUR mount accessories:
APS1 - Air purge system to purge spring chambers
with solenoid valve exhaust.
Operation
Solenoid will not shift without backpressure on ports
2 and 4. Air supply lines to the valve must have I.D.
at least as large as the NPT size of valve ports.
