ATOS solenoid valves are electromagnetically controlled industrial devices, fundamental components for fluid control in automation. They are actuators, not limited to hydraulic or pneumatic systems. Used in industrial control systems to adjust the direction, flow rate, speed, and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, ensuring both accuracy and flexibility. There are many types of solenoid valves, each playing a different role in the control system. Commonly used types include check valves, safety valves, directional control valves, and speed control valves.
Working principle of ATOS solenoid valves:
ATOS solenoid valves contain a sealed chamber with through-holes at different positions, each connecting to a different oil pipe. Inside the chamber is a piston, flanked by two electromagnets. When the coil of one electromagnet is energized, the valve body is attracted to that side. Controlling the movement of the valve body opens or closes different drain holes. The inlet hole is always open, allowing hydraulic oil to enter different drain pipes. The oil pressure then pushes the piston in the cylinder, which in turn moves the piston rod, which in turn drives the mechanical device. Thus, controlling the flow of current to the electromagnets controls the mechanical movement.
Main classifications of ATOS solenoid valves:
1. Based on their operating principle, ATOS solenoid valves are divided into three main categories:
1) Direct-acting solenoid valves:
The principle of ATOS solenoid valves: When energized, the electromagnetic coil generates electromagnetic force that lifts the closing element from the valve seat, opening the valve; when de-energized, the electromagnetic force disappears, and the spring presses the closing element back onto the valve seat, closing the valve. 2) Step-by-Step Direct-Action Solenoid Valve:
The principle of the ATOS solenoid valve: It combines direct-acting and pilot-operated principles. When there is no pressure difference between the inlet and outlet, upon energization, the electromagnetic force directly lifts the pilot valve and the main valve closing element sequentially upwards, opening the valve. When the inlet and outlet reach the starting pressure difference, upon energization, the electromagnetic force actuates the pilot valve, increasing the pressure in the lower chamber of the main valve and decreasing the pressure in the upper chamber, thus using the pressure difference to push the main valve upwards. When de-energized, the pilot valve uses spring force or medium pressure to push the closing element downwards, closing the valve.
Characteristics of the ATOS solenoid valve: It can reliably operate even at zero pressure difference, vacuum, or high pressure, but it has higher power and requires horizontal installation.
3) Pilot-operated solenoid valve:
The principle of the ATOS solenoid valve: When energized, the electromagnetic force opens the pilot orifice, causing the pressure in the upper chamber to drop rapidly. This creates a pressure differential around the closing element, with a lower pressure at the top and a higher pressure at the bottom. The fluid pressure pushes the closing element upward, opening the valve. When de-energized, the spring force closes the pilot orifice. The inlet pressure quickly passes through the bypass orifice, creating a pressure differential around the closing element, with a lower pressure at the bottom and a higher pressure at the top. The fluid pressure pushes the closing element downward, closing the valve.
Characteristics of ATOS solenoid valves: High upper limit of fluid pressure range; can be installed arbitrarily (customization required), but must meet fluid pressure differential conditions.
2. ATOS solenoid valves are divided into six subcategories based on differences in valve structure, materials, and operating principles: direct-acting diaphragm structure, step-by-step direct-acting diaphragm structure, pilot-operated diaphragm structure, direct-acting piston structure, step-by-step direct-acting piston structure, and pilot-operated piston structure.
3. ATOS solenoid valves are classified by function as follows: water solenoid valves, steam solenoid valves, refrigeration solenoid valves, cryogenic solenoid valves, gas solenoid valves, fire-fighting solenoid valves, ammonia solenoid valves, gas solenoid valves, liquid solenoid valves, miniature solenoid valves, pulse solenoid valves, hydraulic solenoid valves, normally open solenoid valves, oil solenoid valves, DC solenoid valves, high-pressure solenoid valves, explosion-proof solenoid valves, etc.
