VV250A Series Diaphragm-Poppet Vacuum Piloted, Vacuum Valves 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. Select from 2 or 3-way function. 20" Hg minimum vacuum required.
