Solenoid Valves

Solenoid Valves

Solenoid valves are well-known in the world of fluid control for their exceptional ability to operate at near-instantaneous speeds, offering rapid and precise opening and closing of flow paths. The rapid switching capability of solenoid valves is a crucial feature in numerous applications across different industries where precise timing and synchronization are essential.

Common solenoid valve applications

  • Automated assembly lines
  • Medical devices
  • Irrigation systems
  • Fuel injection systems
  • Inkjet printers
  • Fire suppression systems
  • Food and beverage processing
  • Water treatment plants
  • Pneumatic conveying systems
  • Gas chromatography
  • Aerospace and aviation
  • Automated car washes
  • Blood analyzers
  • Paint spraying systems
  • Steam boilers

Tameson's solenoid valve categories

Our selection of solenoid valves and related products comes in the following categories:

  • 2-Way solenoid valves: Simple on/off valves with two ports for controlling fluid flow. Ideal for basic applications like water dispensers and air compressors.
  • 3-Way solenoid valves: More complex with three ports, allowing for direction of flow in multiple paths. Used in systems that require mixing or diverting flow.
  • Proportional valves and controllers: Provide precise control by adjusting the valve opening based on electrical signals. Suitable for applications needing variable flow rates, like medical devices.
  • Solenoid valves for pneumatics: Control compressed air in automation systems, operating pneumatic cylinders and devices quickly and reliably.
  • Electric coaxial valves: Used where regular solenoid valves do not suffice. These valves are suited for high-pressure applications (up to 64 bar) and viscous, abrasive, or contaminated media.
  • Hydraulic solenoid valves: Designed for high-pressure hydraulic systems, crucial for equipment like construction machinery and vehicle braking systems.
  • Solenoid valve accessories: Include items like coils, connectors, timers, and revision sets.

Selecting the right solenoid valve

Choosing the correct solenoid valve for your application is essential to ensure optimal performance and longevity. To make an informed decision, consider the following factors:

  • Media compatibility: Identify the type of fluid or gas the valve will control. Ensure the valve's materials are compatible with the media to prevent corrosion or damage.
    • Brass: Affordable and resists corrosion well. Good for water, air, and oils, but not for saltwater or strong acids.
    • Stainless steel: Very durable and great for tough conditions. Handles heat and many harsh chemicals. Common in food, medical, and chemical industries.
    • Plastic: Resists chemicals excellently. Works with corrosive substances and very pure water. Not for hot temperatures or some solvents.
    • Aluminum: Light and mostly corrosion-resistant. Good for air and gasses in pneumatic systems, but not for harsh chemicals or very wet areas.
    • Cast iron: Strong and good for high pressure and heat. Fits water and steam use, but not for acidic or very corrosive fluids. Used in heavy-duty systems like HVAC and water treatment.
  • Operation type: Decide between a normally closed (NC) valve, which remains closed until energized, or a normally open (NO) valve, which stays open until energized. Your choice will depend on the default state required for your system's safety and functionality.
  • Port size and flow rate: Select a valve with the appropriate port size to match your piping. The valve should accommodate the required flow rate without causing excessive pressure drop.
  • Pressure requirements: Check the operating pressure range of the valve. It must be suitable for your system's pressure levels to function correctly and safely.
  • Voltage and power supply: Ensure the solenoid's voltage and power requirements are compatible with your available power supply. Incorrect voltage can lead to malfunction or damage.
    • Direct current (DC): DC solenoids deliver a steady electric charge, offer a uniform holding force, are preferred for battery-powered or mobile devices due to their efficiency with portable power, and are less likely to overheat, making them a good fit for temperature-sensitive environments.
    • Alternating current (AC): AC solenoids cycle their current direction, usually at 50 or 60 Hz, are commonly used where there is a stable power supply, have a strong initial force which benefits certain operations, and can run hotter, thus needing careful heat management.
  • Response time: Consider the valve's response time, especially if your application requires rapid cycling or precise timing.
  • Environment: Account for the operating environment. If the valve will be exposed to harsh conditions, such as extreme temperatures or corrosive substances, choose a valve with the appropriate protection.
  • Certifications and standards: Look for valves that meet industry standards and certifications relevant to your application, ensuring reliability and safety.
