ATOS solenoid valve DH-0832/2/A 74/B in stock
$115.46
The working principle of the Italian ATOS solenoid valve: When energized, the 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, 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 lower pressure at the bottom and higher pressure at the top. The fluid pressure pushes the closing element downward, closing the valve. Features: High upper limit of fluid pressure range; can be installed in any configuration (customization required), but must meet fluid pressure differential conditions.

ATOS solenoid valves are electromagnetically controlled industrial devices, fundamental components of automation used to control fluids. 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.
The selection of ATOS solenoid valves should first follow four principles in order: safety, reliability, applicability, and economy. Secondly, selection should be based on six aspects of the on-site operating conditions (i.e., pipeline parameters, fluid parameters, pressure parameters, electrical parameters, actuation method, and special requirements). ATOS Solenoid Valve Selection Criteria:
1. Selection of Solenoid Valves Based on Pipeline Parameters: Nominal Diameter (DN), Connection Type
1) Determine the nominal diameter (DN) based on the inner diameter of the pipeline or flow requirements.
2) Connection type: Generally, for DN >50, a flange connection should be selected; for DN ≤50, the connection type can be freely selected according to user needs.
2. Selection of Solenoid Valves Based on Fluid Parameters: Material, Temperature Group
1) Corrosive fluids: Corrosion-resistant solenoid valves and all-stainless steel are recommended; Ultra-clean edible fluids: Food-grade stainless steel solenoid valves are recommended.
2) High-Temperature Fluids: Solenoid valves made with high-temperature resistant electrical and sealing materials should be selected, and piston-type valves should be chosen.
3) Fluid State: Fluids can be gaseous, liquid, or mixed, especially when the diameter is greater than DN25, it is essential to distinguish between these states.
4) Fluid Viscosity: Generally, any fluid can be selected below 50 cSt; if it exceeds this value, a high-viscosity solenoid valve should be selected. 3. Selecting Solenoid Valves Based on Pressure Parameters: Principle and Structure
1) Nominal Pressure: This parameter has the same meaning as other general-purpose valves, determined by 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. For a minimum working pressure difference of 0.04 MPa, direct-acting, step-direct-acting, and pilot-operated valves can all be selected.
4. Electrical Selection: AC220V and DC24V voltage specifications should be prioritized for convenience.
5. Selecting Based on Continuous Working Time: Normally Closed, Normally Open, or Continuously Energized
1) When the solenoid valve needs to be open for a long time, and the continuous time 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 valves cannot be selected; a continuously energized type should be chosen. DHI-0631/2/P-X 24DC
