Solenoid Valve Application Tip

Mechanical & Materials Considerations

Solenoid valves are your fastest-acting option when controlling flow. They can be repaired in-line (without breaking plumbing connections in most designs), and they can be less costly than other electrically operated valves.

But there are a few measures that can increase your satisfaction with solenoid valves:
Install strainers or filters to prevent foreign materials from entering the valve and interfering with operation.
  • Avoid Teflon tape; those stringy leftover pieces can travel downstream and hang up in the valve.
  • Use pipe dope sparingly; globs of it in the line can affect solenoid valves and other control elements.
  • Add check valves to your design if it is important to prevent back flow through the solenoid valve.
  • Consider plumbing solenoid valves in series (double-block) where any leakage is unacceptable.
  • Ask for a plated operator to protect special grades of stainless steel from corrosion.
And be sure to let your representative know about everything in the process fluid. Additives in air, water or other fluids can change the soft-seal requirements.
