High Pressure Electro-Mechanical Oil Safety Shut-off Valves

Industrial Grade Electro-Mechanical Safety Shut-off Valve that stops the flow of various grades of oil to the combustion chamber in under a second. Offered in a wide range of body connections, construction materials, with global certifications.

Overview
These electrically actuated valves shut off oil lines in less than one second. A variety of optional body materials and body connections provide reliable operation of these shut off valves even for highly corrosive fuels and for oxygen with MAXON's long-lasting metal-to-metal seating. Application flexibility is provided with 3/8 through 2 diameter line sizes, Cv flow factors up to 218, and line pressures up to 550 PSIG.

Features & Benefits:
  • Electrically actuated valves shut off oil lines reliably
  • Application flexibility provided with 3/8 through 2” diameter line sizes, Cv flow factors up to 218, and line pressures up to 550 PSIG
  • Handles flowing fluid temperatures:
    • Swinging gate bodies from -20°F (-28°C) to +550°F (+288°C)
    • Any ambient temperature from -20°F (-28°C) to +140°F (+60°C)
  • Various application requirements met with manual reset or automatic reset motorized operators
