Overall dimensions and technical information are provided solely for informative purposes and may be modified without notice Spool valves and solenoid valves Series 888 1 Air distribution 1 | 77 Series 888 General Competitively priced, good performance and versatility combined with a compact design are the main characteristics of this new series of valves. The aluminium valve body and spool/seal arrangement optimize both the flow rate and the valve switching time. This series of valves are available with G1/8” and G1/4” ports in 3/2, 5/2 and 5/3 versions. Monostable or bistable versions are available and include an integrated technopolymer solenoid operator with 9mm stem and built in manual override. Solenoid valves series 888 are available in point-to-point and serial configurations. For serial system specifications, see Optyma-F series. The valves can be supplied with or without the solenoid coil, however, if the solenoid coil is required please refer to the following table: Voltages Coil Code Voltage Code Direct current DC 12V (3,5W) MF4 F04 24V (3,5W) MF5 F05 Alternating current AC 50 - 60 Hz 24V (3,7W) MF56 F56 110V (3,7W) MF57 F57 230V (3,7W) MF58 F58 Connectors Coding Voltages Kit 100 pieces DC/AC 24V 888.11.01L-K Alternating current AC 50 - 60 Hz 110V 888.11.02L-K 230V 888.11.03L-K Construction characteristics Body Aluminium Operators Technopolymer Aluminium for spring bottom plates Seals NBR Spools Aluminium Springs Spring steel Pistons Technopolymer Use and maintenance These valves have an average life of 15 million cycles depending on the application and air quality, filtered and lubricated air using specified lubricants will dramatically reduce the wear of the seals and ensures long and trouble free operation. Please ensure that the valve is being used according with the manufacturers specification, such as air pressure and temperature. The exhaust ports 3 and 5 must be protected against the possible ingress of dirt or debris. Repair kits including the spool complete with seals are available for overhauling the valves; however, although this is a simple operation it should be carried out by a competent person.
