ATOS Solenoid Valve Pressure Parameters:

1) Nominal Pressure: This parameter has the same meaning as other general valves and is determined based on the nominal pressure of the pipeline;

2) Working Pressure: If the working pressure is low, a direct-acting or step-direct-acting principle must be selected; when the minimum working pressure difference is above 0.04 MPa, direct-acting, step-direct-acting, and pilot-operated valves can all be selected. 4. Electrical Selection: AC220V or DC24V voltage specifications are preferred for ease of use.

5. Selection Based on Continuous Operating Time: Normally Closed, Normally Open, or Continuously Energized

1) When the solenoid valve needs to be open for a long time, and the duration is longer than the closing time, a normally open type should be selected.

2) If the opening time is short or the opening and closing times are infrequent, a normally closed type should be selected.

3) However, for some safety protection applications, such as furnace and kiln flame monitoring, normally open types cannot be selected; continuously energized types should be chosen.

6. Selection of Auxiliary Functions Based on Environmental Requirements: Explosion-proof, check valve, manual operation, waterproof mist, water spray, submersible.

ATOS Solenoid Valve Selection Principles:

ATOS Solenoid Valve Safety:

1. Corrosive Media: Plastic King Solenoid Valves and All-Stainless Steel Valves are recommended; for highly corrosive media, diaphragm type valves must be selected. 1. For neutral media, solenoid valves with copper alloy valve bodies are preferable; otherwise, rust particles will frequently flake off from the valve body, especially in applications with infrequent operation. Copper cannot be used for ammonia valves.

2. Explosive environments: Appropriate explosion-proof products must be selected. For outdoor installations or dusty environments, waterproof and dustproof models should be chosen.

3. The nominal pressure of the solenoid valve should exceed the maximum working pressure in the pipe.

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, 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 media pressure to push the closing element downwards, closing the valve.

The ATOS solenoid valve has 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.

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, energizing the valve causes the electromagnetic force to directly lift 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, causing the pressure in the lower chamber of the main valve to rise and the pressure in the upper chamber to fall. This pressure difference pushes 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.
