A malfunction of an ASCO solenoid valve will directly affect the operation of switching and regulating valves. Common malfunctions include the solenoid valve not operating. The following troubleshooting steps should be taken:

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, the manual button on the coil can be switched from the normal "0" position to the "1" position to open the valve.

3. Solenoid Valve Jammed: The clearance between the solenoid valve's spool sleeve and valve core is very small (less than 0.008mm), and it is usually assembled as a single piece. When mechanical impurities are introduced or there is insufficient lubrication, it can easily become jammed. A temporary fix 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 there is sufficient lubrication.

4. Air Leakage: Air leakage will cause insufficient air pressure, making it difficult for the forced valve to open and close. This is caused by damaged gaskets or worn spool sleeves, resulting in air leakage between several cavities. When troubleshooting solenoid valve malfunctions in switching systems, choose an appropriate time to address the issue when the solenoid valve is de-energized. If the problem cannot be resolved within one switching interval, pause the switching system and address the issue at a later time. ASCO Solenoid Valve Selection Criteria (USA):

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, flange connections are required for DN > 50; for DN ≤ 50, the choice is flexible based on 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 are preferred.

3) Fluid State: Fluids can be gaseous, liquid, or mixed, especially for diameters greater than DN 25.

4) Fluid Viscosity: Generally, any fluid can be selected below 50 cSt; if this value is exceeded, a high-viscosity solenoid valve should be used. 3. Selecting Solenoid Valves Based on Pressure Parameters: Principle and Structural Types

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; 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 should be prioritized for convenience.

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

ASCO solenoid valves (USA) are electromagnetically controlled industrial devices, fundamental components for fluid control automation, belonging to actuators, and are not limited to hydraulic or pneumatic systems. They are 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, while ensuring control accuracy and flexibility. There are many types of solenoid valves, each playing a different role in a control system. The most common types include check valves, safety valves, directional control valves, and speed control valves.

Key Features of ASCO Solenoid Valves:

External leakage is completely eliminated, internal leakage is easily controlled, and operation is safe. Internal and external leakage are safety hazards. Other automatic control valves typically have an extended valve stem, with the valve core's rotation or movement controlled by an electric, pneumatic, or hydraulic actuator. This requires solving the problem of external leakage from the dynamic seal of the valve stem during long-term operation. Only ASCO solenoid valves use electromagnetic force acting on an iron core sealed within a magnetically shielded sleeve in electric control valves, eliminating the dynamic seal and easily preventing external leakage. Electric valves are difficult to control torque, easily leading to internal leakage, and even breaking the valve stem head. The structure of ASCO solenoid valves easily controls internal leakage, reducing it to zero. Therefore, ASCO solenoid valves are particularly safe to use, especially for corrosive, toxic, or high/low temperature media. ASCO Solenoid Valves (USA)
