Stainless steel solenoid valve price | stainless steel solenoid valve dimensions | stainless steel solenoid valve principle | the role of the history of the development of stainless steel solenoid valve of stainless steel solenoid valve, so far, domestic and international stainless steel solenoid valve from the principle divided into three categories (ie: direct-acting step direct acting, pilot operated) from the difference between the different principles on the structure and materials of the valve is divided into six branch subclasses (straight diaphragm structure, step-by-step diaphragm structure of the pilot film sheet structure, direct-acting piston structure, step-by-step piston structure, the pilot piston structure). (A), direct-acting stainless steel solenoid valve principle: power, the electromagnetic coil generates electromagnetic force the closure of parts brought from the seat, the valve opens; power, the electromagnetic force disappears, the spring force to close the pressure in the valve seat , the valve closes. Features: can work in a vacuum, negative pressure, zero pressure, but the general path of not more than 25mm. (B), step-by-step direct-acting stainless steel solenoid valve principle: it is a direct-acting and pilot - a combination of principle, when the inlet and outlet differential pressure ≤ 0.05Mpa, energized, the electromagnetic force directly to the pilot valve and main valve closure of parts in turn lift the valve opens. When the inlet pressure difference> 0.05Mpa, power, electromagnetic force first to open the pilot valve, main valve cavity pressure rise on the cavity pressure decreased, thus the differential pressure to the main valve is pushed upwards; power failure, the pilot valve promote the closure of parts and the main valve spring force or medium pressure, move down, so that the valve is closed. (C) pilot stainless steel solenoid valve Principle: power, the electromagnetic force to open the pilot hole on the chamber pressure fell rapidly close the pieces around the formation of low and high differential pressure, promote the closure of parts to move up, the valve opens; energized, the spring force to the pilot hole Close the inlet pressure into the upper plenum off valve formed around a high pressure differential through the bypass hole quickly, to promote the closure of parts moving down, close the valve.
