New solenoid valve requires no differential pressure to close
January 10, 2003
New corrosion-resistant, all-plastic solenoid valve features a design that permits the valves to close regardless of the differential pressure across them. Ordinary solenoid valves often require pressure differentials of up to 25 psi to operate effectively. Now, designers of systems requiring an instant on/off, corrosion-resistant or non-contaminating solenoid valve can choose a valve that offers more system design flexibility. Solenoid valves feature a coil that rectifies AC current to DC current, resulting in low coil operating temperatures than would be otherwise possible, and allows the coil to be rated for 100 percent continuous duty applications.
