Air-Sol 2-Way Process Solenoid Valve is a 2-way, 2-position, normally closed or normally open valve for the control of air, oil, water, or media that is compatible with valve materials of manufacture. The valve features an all brass body and a 0 minimum pressure differential while still boasting a full flow 1/2" orifice. The encapsulated coil construction ensures that the valve functions well under long periods of energization (100% duty), as well as providing a high degree of environmental protection (NEMA 4). The inner valve functions as a direct assist using a flat diaphragm and orifice plate. Pressure differentials shift the valve to full open or full closed. A push, non-locking manual override is standard. Viton seals. Meets FDA standards. Temperature range: (fluid 90-deg C max.) ambient -10 to +50-deg C. Media: air, oil, inert gas, water, emulsion. Normally closed. Seals: Viton.
