◇ Overview and Features DKF solenoid air valves, for changing the direction of flow of the gas pipeline. Widely used to control water, fire stations and other industrial sectors of the compressed air system is the control element hydropower units and automatic brake control element qi. The valve has a small size, reliability, long life and other characteristics. Can be long-term power, and with manual operation knob under power failure conditions, (when the work automatically, manually dial the "-" must be in a horizontal position) manually ◇ works (see below) when the pilot valve (1 ) is not energized, pressurized gas from the chamber into the P, due to the pressure and the spring force, the decline of the core (5) moves upward, air solenoid valve is closed, while leading to T A chamber cavity; when the pilot valve (1) is energized , the pilot valve is opened, the slide cores (3) moves downward, pushing down the decline in core moving, opens the solenoid air valve, P A leading chamber cavity, T closed chamber. ◇ main technical parameters 1) Working pressure range: 0.3 ~ 1MPa 2) Nominal Diameter: Φ10mm, Φ15mm 3) Connection: standard pipe header. 4) Working media: non-corrosive gases. 5) Power supply voltage: DC110V, DC220V, AC220V 6) work: long when the power or manual operation. ◇ appearance and installation dimensions diameter H H1 L1 × L2 L3 ABC KM nd Model 10 165 40 72 × 40 50 32 16 16 3-M16 × 1.5 3-Φ7 DKF-15 15 165 40 72 × 40 50 36 16 16 3 -M22 × 1.5 3-Φ7 DKF-20 20 180 46 78 × 42 50 45 22.5 22.5 3-M27 × 2 3-Φ7
