The 250 Series Diaphragm-Poppet Vacuum Solenoid Valve are ideal for dry, vapor or dirt laden vacuum systems. The greater the vacuum, the tighter these valves will seal. When compared to other vacuum valves, the diaphragm-poppet is more reliable, particularly in poor ambient conditions. Excellent flow. Externally vacuum piloted, select from 2 or 3-way, normally closed or open in a variety of voltages. 20″ Hg minimum vacuum required.
