S25N NAMUR Directional Valve |
|
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.
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.
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.
CV = 1.8
Flow Schematics:
(Port 1 - air supply)
3-way Valve (Spring Return Actuators)
2 4
3 1 5
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.
4-way Valve (Double-acting Actuators)
2 4
3 1 5
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.
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.
FC1, FCSR and FCDA - Single port and dual port exhaust flow controls.
LV1 - Lockout and vent valve for lockout and manual override applications.
Automax sandwich NAMUR mount accessories provide compact, clean control packages for the SuperNova actuator.
