ATOS solenoid valve DHU-0631/2/A-X 24DC in stock
$148.32
The Italian ATOS valve operates as follows: 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 then pushes the closing element upward, opening the valve. When de-energized, spring force closes the pilot orifice. The inlet pressure quickly passes through the bypass orifice, creating a pressure differential around the closing element, with lower pressure at the bottom and higher pressure at the top. The fluid pressure then pushes the closing element downward, closing the valve.

Italian ATOS solenoid valves are electromagnetically controlled industrial devices, fundamental components for fluid control 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 precision 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. A malfunctioning solenoid valve directly affects the operation of switching and regulating valves. Common malfunctions include the solenoid valve failing to operate. Troubleshooting should focus on the following:
1. Loose or detached solenoid valve wiring: The solenoid valve will not receive power. Tighten the wiring.
2. Burned-out solenoid valve coil: Disconnect the solenoid valve wiring and use a multimeter to measure. If an open circuit is detected, the solenoid valve coil is burnt out. This can be caused by moisture in the coil, leading to poor insulation and magnetic leakage, resulting in excessive current and burnout. Therefore, prevent rainwater from entering the solenoid valve. Additionally, an overly stiff spring, excessive reaction force, or insufficient coil turns can also cause coil burnout. In an emergency, switch the manual button on the coil from the normal "0" position to the "1" position to open the valve.
3. Solenoid valve stuck: The clearance between the solenoid valve's spool and valve core is very small (less than 0.008mm), and they are usually assembled as a single piece. When mechanical impurities are introduced or there is insufficient lubrication, the valve can easily become stuck. One possible solution is to insert a steel wire through the small hole at the head to make it spring back. The fundamental solution is to disassemble the solenoid valve, remove the valve core and valve core sleeve, and clean them with CCI4 to ensure the valve core moves freely within the valve sleeve. During disassembly, pay attention to the assembly sequence of each component and the location of external wiring to ensure correct reassembly and wiring. Also check if the lubricator spray hole is blocked and if the lubricating oil is sufficient.
4. Air Leakage: Air leakage will cause insufficient air pressure, making it difficult to open and close the forced valve. This is caused by damaged gaskets or worn spool valves, resulting in air leakage between several cavities. When troubleshooting a solenoid valve malfunction in a switching system, choose an appropriate time to address the issue when the solenoid valve is de-energized. If the problem cannot be resolved within a single switching interval, pause the switching system and address it at a later time.
The Italian ATOS solenoid valve is an electromagnetically controlled industrial device, a fundamental component of automation used to control fluids. It is an actuator, not limited to hydraulic or pneumatic systems. It is used in industrial control systems to adjust the direction, flow rate, speed, and other parameters of the medium.

There are many types of solenoid valves, each playing a different role in a control system. Types include check valves, safety valves, directional control valves, and speed control valves.
Performance requirements for Italian ATOS solenoid valves:
1. Reversing Performance: Under specified operating conditions, the solenoid valve must reliably reverse direction after being energized and reliably reset after being de-energized.
2. Pressure Loss: The pressure loss of a solenoid directional valve consists of flow loss and throttling loss as fluid flows through the valve orifice.
3. Internal Leakage: The internal leakage of a solenoid directional valve refers to the leakage from the high-pressure chamber to the low-pressure chamber under specified operating conditions and in various operating positions.
4. Reversing and Reset Time: The time required from energizing the solenoid to the termination of the valve core's reversal; the reset time is the time required from de-energizing the solenoid to the valve core returning to its initial position. 5. Switching Frequency
Maximum number of switching operations allowed per unit time
6. Service Life
ATOS solenoid valves from Italy are used until major components are damaged, preventing normal switching and reset actions, or until their main performance indicators significantly deteriorate beyond the specified number of switching operations. [1]
