Solenoid Valves

Solenoid valves are electromechanical devices that control the flow of fluids or gases in a system. They operate by using an electric current to generate a magnetic field, which then moves a plunger or a diaphragm to open or close the valve. Two primary types exist (direct and acting) solenoid valves and pilot-operated solenoid valves. Direct-acting solenoid valves use the magnetic field to directly move the valve’s seal, making them ideal for low-pressure systems. On the other hand, pilot-operated solenoid valves use the system’s pressure to open and close the valve, suitable for high-pressure systems. The evolution and variety of designs in solenoid valves ensure a suitable solution for the most demanding process requirements.


Application Features:


  • Electromagnetic Operation: Solenoid valves use an electrical current to generate a magnetic field, which drives the valve’s operation, leading to precise control.
  • Versatility: These valves cater to various application needs, be it low-pressure or high-pressure systems, owing to the two main types (direct-acting and pilot-operated).
  • Reliability: Solenoid valves have proven their reliability over time, suitable for a diverse range of applications, including aggressive media or precision flow control.
  • Compact Design: Due to their electromechanical design, solenoid valves can be made relatively small, making them suitable for systems where space is a constraint.
  • Quick Response Time: Solenoid valves can open and close rapidly, enabling quick control of the fluid or gas flow in the system.
  • Automated Control: As they are electrically operated, solenoid valves can easily be integrated with automated control systems.
