GENERAL PURPOSE VALVES
Note: This valve also available as an operator. Refer to following page.
OPERATING CONDITIONS
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.
Media: Air, water, and other fluids compatible with standard Buna seals. Hot water, steam, gasoline, and many oils require special seal materials. (Series 50 pressure ratings may change due to the viscosity of the liquid.)*
Valve Temperature Range: Standard Valves – 0°F (-18°C) to 104°F (40°C) ambient;
0°F (-18°C) to 150°F (65°C) media. Optional Valves - can tolerate much higher or much lower ambient and media temperatures.*
