HAZARDOUS LOCATION VALVES
Note: This valve also available as an operator. Refer to following page.
OPERATING CONDITIONS
Media: Air, and other fluids compatible with standard Buna seals. Hot water, steam, gasoline, oils, some hydraulic fluids, and many media 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 140°F (60°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.*
