◇ Overview and Features DKL-B23-type two-way solenoid air valves, is specially designed for unattended operation or remote controlled automation systems designed for the high demands for changing the direction of flow of the gas pipeline, the control airflow off. Suitable for hydro shutdown process, the control element compressed air braking mechanism can also be used as the control element exhaust air shroud charge, it is possible to reliably keep working. Widely used to control hydropower plants, thermal power plants and other industrial sectors of the compressed air system. The valve is made of stainless steel materials, mechatronics design, small size, reliability, aesthetic appearance, long service life. And the valve has the advantage of the original state memory function. ◇ main technical parameters 1) Working pressure: 0.3 ~ 1MPa. 2) Nominal diameter: Φ10mm, Φ15mm, Φ20mm. 3) Connection: standard pipe joint connection (GB3733). 4) Working media: non-corrosive gases. 5) Power supply voltage: DC110V, DC220V, AC220V. 6) Medium temperature: less than 60 ℃ operation program: 1, dynamic operating conditions :( gas is introduced into the pressure chamber P, the two solenoid pilot valve manual knob must be in parallel with the longitudinal axis of the "|" position) ③ open. : When the two-way solenoid pilot valve is energized, the main valve to open under the action of the piston, pressurized gas into the chamber A chamber from P, while the trip valve is open, implement pilot valve in case of power failure, the main valve to maintain the existing work state. ④ Close: When the two-way solenoid pilot valve is energized, the role of the main valve pressure is closed, while the trip valve is closed, to achieve after the pilot valve power, reset state self-holding. 2, for (condition to enter the gas chamber pressure P, solenoid pilot valves in case of power failure.) A) ON: In the manual knob two-way solenoid pilot valve in parallel with the longitudinal axis of the "|" position under the circumstances, rotating two-way solenoid pilot valve manual knob, and turn it on manually, action programs such as the program automatically open. b) Close: rotating two-way solenoid pilot valve manual knob, achieve closure manually operated, action programs such as automatic shutdown procedures. 3, original memory function: when the case of a power and gas supply are gone, and the main valve in the action of the spring in the off original state. ◇ Model Description DKL - B23- □ - □ / □ Operating Voltage (V) rated medium pressure (MPa) Nominal Diameter (mm) Horizontal air solenoid valve model (two-way)
