2 ir-piloted Valves Features Since the unit requires air piping only, with no need for electrical wiring, it can be handled by a person without fear of electrical shocks or current leakage. Using no electricity means that expensive equipment to protect against explosions, special precautions, or measures against electric noise are not to be required. Unlike electrical equipment, the construction is simple. The associated limit valve is also durable and can be used for long periods. ecause harmless compressed air is used, there is no need for major construction work on the main or pilot air line unlike that of hydraulic piping, and piping work is simple enough for anyone trained to perform. The power source is always compressed air, so that the system can be easily used where no power supply exists. In addition, it retains memory for about several dozen minutes, and can therefore continue operations even during power outages. ilot cap Upper side ody Lower side with holes eturn spring ody cap ase ILOT type basic construction (125 type) Koganei ir-piloted Valves Features ssured operation Sharp, switching characterized by poppet and diaphragm construction. The valve seat is also reliable. (Quick switching of main pressure helps to keep valve seat seal performance.) Few breakdowns occur in this construction. The construction is extremely simple. poppet-type prevents galling or other problems, even if small foreign objects have entered inside. nd no sticking occurs even if the unit is left unused for long periods of time. It can be used without lubrication. With virtually no sliding parts, there is no need for lubrication other than for a few specific models. This means no breakdown due to insufficient lubrication. Tolerates frequent operations for long operating life The small mass and stroke of the moving parts means a small inertial force which, along with construction with the large-capacity synthetic rubber for absorbing impacts, ensures continuous high-frequency operations and a long operating life. ny mounting direction acceptable No matter what direction is used for mounting, the construction causes no trouble to the operation. Compact and lightweight unique, compact design, with a body of light aluminum alloy. pplication Examples of ir-piloted Valves iston poppet-type basic construction (501 type) Using as a large-sized stop valve ir cylinder operation Switching of air pressure signal ILOT ilot cap iston seal iston iston seal oppet ody oppet eturn spring ody cap Valve a Circuit diagrams a ir tank ilot line 3-port NC valve 125V, etc. ir-piloted valves 3-port NC 1250, etc. Chart a Valve air Valve a ilot air a ilot line air Valve ir-piloted valves Internal pilot 2-, 3-port NC valve holding type Valve b for retracting cylinder 4-, 5-port 125-2, etc. (501-4, etc.) 2-port NC valve for retracting cylinder 125MC, etc. Circuit diagrams ir cylinder b For start ilot air a ilot line b c ilot line d 3-port valve for switching signal 125V, etc. air Signal Signal C C Signal C D D Signal D ir-piloted valves ir-piloted valves 3-port NC 3-port 250, etc , etc. ir cylinder operation ilot air a IN Valve a ilot line air ir-piloted valves 4-, 5-port 3-port NC valve254-4, etc. 125, etc. Circuit diagrams Valve Chart a The air cylinder rod extends only as long as pilot valve a is pressed down. ir cylinder Chart a b Momentarily push pilot valve a to switch air-piloted valve, and then maintain that condition. fter switching, let the air cylinder rod extend, and then push down limit valve b. ushing b exhausts air from the pilot line, switches off air-piloted valve, and the air cylinder rod retracts.

Normal operating range Cylinder speed mm/s [ in./sec.] This area presents high cylinder speed is required. (Cylinder speed: min mm/s [ in./sec.]) Cylinder speed max mm/s [ in./sec.], min. 50mm/s [2.0in./sec.] Notes : 1. While the speeds shown in this graph assume an air supply pressure of Ma [73psi.] and a load ratio of 0, the speeds will be virtually the same in the range of Ma [58102psi.], and up to a load ratio of about 30 %. 2. In general, select a valve with a margin of about 50 % for the required cylinder speed, and then use a speed controller to reduce the speed in operation. 3. In considering the time required for the cylinder to make one stroke, the cylinder delay time and cushioning time need to be considered alongside the cylinder speed. Differences between Type and Type ir-piloted Valves type valves (Continuous pilot pressure is needed to maintain the operating condition.) ilot valve 3-port Normal condition type Valves Operating condition ( ) The difference from the type valve is the existence of a bypass hole (small hole) on the stem. This helps the pilot valve to maintain its operating condition during a momentary operation. It is able to maintain the operating condition even if a certain amount of air leaks from the pilot line. ilot valve 2 ports ilot valve 2 ports or 3 ports ypass Normal condition Operating condition Holding condition eturn condition Note :These shematic diagrams show the diaphragm type, 3-port valves. The bypass for the 4, 5-port valve is on the side stem. See the Operating rinciples for the type on p.946. Safety recautions (ir-piloted valves) Warning Caution Others 1. ll types other than the 2 (double pilot) type are designed to use air as the media. For other media, consult us. 2. lways check the Catalog, etc., when performing piping to products to ensure that the connections are correctly done. Wrong piping could result in abnormal operation of the actuator, etc. For locations subject to water or to large amounts of dust, use a cover, etc., to protect the valve. In addition, install a muffler, etc., to the port to prevent entering of dust. Intrusion of water or dust could result in short-term functional breakdowns, or in sudden drops in performance or reduced operating life. 1. Use main air pressure higher than the minimum operating pressure listed in the Catalog. 2. Set the pilot pressure to a level suitable to the main pressure. n unnecessarily high pressure can shorten the operating life. 3. If excessively throttling the port for operation, set the pilot pressure at the main pressure or higher ( type). For details, see the specifications of each series. 4. The type (internal pilot holding type) cannot be used as a 2-port valve. For a large air flow rate, provide sufficient air supply. In addition, the port cannot be used in a choked condition. Install speed controllers between the valve and cylinder. 5. s with the normal type, use a pilot valve size that offers enough margin when the type is operated as a single pilot valve. In this case, set the main and pilot valves to the same pressure.

Handling recautions Order Codes pplication Examples Mounting hole Do not apply higher pressure than the specified pilot pressure. Use an oil-removing air filter, etc., to prevent impure compressor oil, etc., from entering. To prevent clogging, supply the main line air through the filter to prevent solid objects from mixing into the flow.
