Safety precautions lways read this section before starting use. Pilot operated 2 port solenoid valve (P/D) and pilot kick type 2 port solenoid valve (PK/DK) 1 1 2 1 2 3 Design & Selection WRNIN Working fluid (1) When using this valve for dry air or inert gas, the life can be shortened considerably due to wear. Use a valve for dry air. (2) This valve cannot be used for maintaining the vacuum. CUTION Fluid viscosity The fluid viscosity must be mm 2 /s. Malfunctions could occur if the viscosity is higher than mm 2 /s. (This value is 20 mm 2 /s for the PK Series.) Leakage current from other fluid control components When operating the solenoid valve with CR circuit a programmable controller, etc., check that the output leakage current from the programmable controller is within the following specifications. Voltage Series no. P, D PK, DK Solenoid valve diode DC 100 V 200 V 100 V 200 V 12 V 24 V 6 m 6 m 3 m 3 m 2 m 2 m Triode switch Programmable controller side 1 m 1 m 2 m 2 m Installation, Piping & Wiring CUTION 1 m 1 m Installation (1) s a general rule, the valve must be installed vertically with the coil facing upward. Piping (1) If the pipe vibrates when the solenoid valve is opened and closed, securely fix the piping. (2) When passing steam, steam generated from a boiler will contain a large amount of drainage. lways install a drain trap. (3) When passing steam, water replenished to the boiler will contain matters such as "calcium salt" and "magnesium salt". These matters will react with oxygen and carbon oxide causing scales and sludge, so always install a "water softener" and a filter for steam. (4) When the regulator and solenoid valve are directly coupled, the parts could mutually vibrate causing resonance and chattering. (5) If the piping cross-section area on the fluid inlet is reduced, the operation may become unstable due to a differential pressure fault during valve operation. The piping on the fluid inlet must have a size that matches the valve port size. Wiring (1) Refer to page 53 in the Introduction for details on connecting the terminal box. C R Leakage current CUTION When Using 1 Instantaneous leakage With the pilot operated type or pilot kick type 2 port valve, if sudden pressure is applied when the pump starts while the valve is closed, the valve may open for an instant causing fluid to leak. Caution is required during use. 2 Operation Do not apply back pressure. The valve could malfunction. 3 Water hammer If water hammering occurs causing a problem, consider using the CKD "WL type" or "RSV type" solenoid valve or a motor valve. 4 Manual operation lways observe the following points when using a manual override. <For NO (normally open) type> Opening: Insert a flat-tip screwdriver into the slit on the manual shaft, and turn it approx. 120 to the right or left. The plunger will rise up, and the valve will open. The open state is held even when the screwdriver is removed. lways return the valve to the original position after use. Closing: Turn the manual shaft from the open position to the vertical position. The plunger will lower and the valve will close. (Refer to the following drawings.) C O Valve closed O C Valve opened <For NO (normally open) type> (1) Closing the valve with manual operations The manual shaft is threaded, so hold the manual dial and rotate the shaft clockwise. When the manual dial has been rotated downward 5 to 6 mm and no longer rotates, the solenoid valve will switch to closing operation. (2) Resetting (when not using manual override) lways rotate the manual dial counterclockwise and return it to the highest point. Manual dial Manual shaft Right-handed thread C O Valve opened 226
1 2 2 CUTION Maintenance Thermal insulation cover When piping for steam or hot water, etc., use an insulating cover structure that can be disassembled for maintenance purposes. void placing an insulating cover on the entire solenoid valve or on the coil section. The coil could burn. Tightening torque When disassembling or assembling, tighten the body bolt, core assembly and nut with the following tightening torques.
