HOW IT WORKS Compressed air to the SUPPLY port, fills bottom cavity (BLUE), and underside of the bottom diaphragm, causing the poppet to seat and seal. VALVE WILL NOT LEAK. Valve actuation (at top) overcomes force to the underside of the bottom diaphragm, and opens flow to the COMMON port. High flow, no sliding seals. VALVE CANNOT STICK. Pilot Port Releasing the actuation permits bottom diaphragm to begin valve closing. Compressed air assists valve shift. Exhausting pressure under the top diaphragm (GREEN) assists the position change and creates “Quick Dump” feature to EXHAUST. Note: Design provides an excellent, leak free, two-way function with plugged Exhaust port. APPLICATION EXAMPLES FOR DIAPHRAGM-POPPET VALVES Industrial Automation: Rugged, Reliable. Withstands difficult conditions. Petrochemical: Simple design works well in demanding media and harsh environments. Medical: Inert construction and leak proof. Ideal for clean/alternate media. Transportation: Long history of reliability in extreme conditions and climates. Food and Beverage: Performs well with moisture laden air.
