Series 50 Model 53
3-Way Normally Closed Valve (exhaust to atmosphere)
Our original mini — engineered for space economy without sacrificing performance. Typical applications include medical, analytical instrumentation. Air, water, and other fluids compatible with standard Buna seals. Hot water, steam, gasoline, and many oils require special seal materials.
• Smaller than the Series 30 but larger than the Series 58 and 15 valves.
• Tough with options to use in hazardous location environments or low watt applications.
• High quality engineering.
