Installation Instructions
The Automax S25N directional valve is installed very
easily to any SuperNova series actuator.
1. Place the gasket seal provided into the gasket bore on the face
of the valve. The gasket seal should be completely seated in the
bore.
2. Place the actuator with the two ports facing you, and the pinion
pointing up. Orient the Automax solenoid valve with the gasket
seal toward the actuator and the operator towards the right.
3. The valve is then mounted to the actuator with the two screws
provided. Apply Loctite Threadlocker 222 or equal to the screws
prior to assembly.
4. Connect the air supply to port #1 and wire solenoid per local
and national electrical codes. The assembly is now ready for
operation.
5. Optional porous bronze vents (P/N 101602) or adjustable
speed controls (P/N 100531) can be added to ports #3 & #5.
6. The S25N directional valve is easily converted from 4-way to
3-way configuration (see figures below right). With the NAMUR
interface facing forward, move the conversion plug from the
left to righthand port to convert to 3-way configuration.
The flathead screw will lift conversion plug out of port.
Tighten screw to secure
conversion plug.

Ordering Guide
Lubrication:
• Lubrication of Automax products is not required
but is recommended to maximize service life. Where
devices not made by Automax are used in the system
the manufacturer should be consulted regarding their
lubrication requirements.
• Lubricators should be installed downstream of regulators
per the manufacturer's instructions.
• Automax positioner supply air must be clean, dry and
oil free. Do not use lubricators in conjunction with
Automax positioners.
• Oils used in air line lubricators should be compatible with
seals used in the system. Generally Automax products use
Buna-N (Nitrile) with Viton seals available as an option.
Oils should be petroleum based with oxidation inhibitors,
an ISO 32 or lighter viscosity, and an aniline point between
82
° C (180 ° F) and 104 ° C (220 ° F).
Note: See appropriate IOM's for installation of
sandwich NAMUR mount accessories.
