ATOS Solenoid Valve Working Principle:

ATOS solenoid valves contain a sealed chamber with through-holes at different locations, 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. Solenoid valves are classified into three main categories based on their operating principle:

1) Direct-acting solenoid valves:

ATOS solenoid valve principle: 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.

ATOS solenoid valve characteristics: Operates normally under vacuum, negative pressure, and zero pressure, but the nominal diameter is generally no more than 25mm.

2) Step-by-Step Direct-Action Solenoid Valve:

ATOS Solenoid Valve Principle: 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, 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 open. When de-energized, the pilot valve uses spring force or medium pressure to push the closing element downwards, closing the valve.

ATOS Solenoid Valve Features: Reliable operation even at zero pressure difference, vacuum, or high pressure, but requires higher power and must be installed horizontally.

3) Pilot-operated solenoid valve:

ATOS solenoid valve principle: When energized, electromagnetic force opens the pilot orifice, causing a rapid drop in pressure in the upper chamber. This creates a pressure differential around the closing element, with lower pressure at the top and higher pressure at the bottom. The fluid pressure pushes the closing element upward, opening the valve. When de-energized, spring force closes the pilot orifice. The inlet pressure quickly creates a pressure differential around the closing element through the bypass orifice, with lower pressure at the bottom and higher pressure at the top. The fluid pressure pushes the closing element downward, closing the valve.

ATOS solenoid valve features: 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.
