Refer to the safety instructions and precautions section for the products mentioned in this catalog. Selection 1 For NAC, 4, NAC4, 44 with float type auto drain (N.O.), use 2.2kW {2 l/min (ANR)} or larger compressor. Because two auto drains are used and 2 l/min air is needed, it might cause a malfunction with a compressor weaker than the required ability. Installation 1 Flush piping before installation. 2 Use of piping adapters will ease installation. 3 The regulator may be installed with the adjustment knob up or down. If using the pressure switch (IS1M) and/or the T-type spacer, the regulator knob must face down. 4 The NAKM check valve is designed to be used between the regulator and the lubricator when it is necessary to prevent the possibility of lubricant flowing back into a non-lubricated secondary supply line. 5 When mounting residual pressure release 3- port valve upstream of a lubricator, use check valve (series NAKM) to prevent reverse flow of oil. 6 Pressure switch and T-type interface cannot be mounted to OUT side of residual pressure release 3-port valve. Piping Warning: When mounting check valve, make sure of the position of mark which indicates air flow direction. 44

Principal of Operation NAR 1, 26, 256, 6, 46, 56, 66 When primary pressure (P1) is higher than the secondary pressure (P2), the operation follows that of a standard regulator (see Figure 1 ). If P1 is exhausted by shifting a valve, P1 is reduced and the pressure under the regulator valve 4 will vent to P1. Therefore, the force pushing on the regulator valve 4 will be reduced to only the valve spring 5 which opens the passage from P2 to P1. This slowly decreases the pressure in the lower chamber of the diaphragm 1 and the force of the adjustment spring 3 exerts a force directly to the valve stem. This completely opens the flow path from P2 to P1 (see Figure 2 ) and quickly exhausts the pressure from P2 to P1. When primary pressure (P1) is higher than the secondary pressure (P2), the internal check valve 2 will seat, and the operation follows that of a standard regulator (see Figure 1 ). If P1 is exhausted by shifting a valve, the internal check valve 2 will crack open (P1 is less than the pressure in the lower diaphragm chamber 1). See Figure 2. The force of the adjustment spring 3 pushes directly on the valve stem and opens the Flow path from P2 to P1 completely (see Figure 3 ) and quickly exhausts the pressure from P2 to P1. ❶ Modular Air Components Setting The adjustment knob is the locking type. Pull the knob away from the body until the orange band is visible. Adjust as necessary and push the knob back into its locked position to prevent accidental setting change. ❷ Turning the adjustment knob clockwise increases the pressure and turning the knob counter clockwise will reduce the pressure. Check supply pressure before adjusting pressure. Precautions <Installation> ❶ Air flush piping before installation. ❷ Install with at least 2.5 in. of free space below the unit to allow easy access. 5

(See fig. 2). In the bottom valve chamber, the secondary pressure flows through the clearance between the valve and valve stem. When the primary pressure is blocked, the check seal folds and the pressure in the bottom valve chamber passes to the primary pressure side (see fig. 3). Because the flow area of the check seal is larger than that of the clearance between the valve and valve stem, differential pressure is created between the top and bottom chambers of the valve and the valve opens. The diaphragm is then pushed up by the pressure adjustment spring to let the valve fully open. The secondary pressure then rapidly discharges to the primary pressure side.
