Series 50 Model 55

3-Way Directional Control Valve

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.

• Tough with options to use in hazardous location environments or low watt applications.
• High quality engineering.
