It is designed for use in temperatures up to 900°F Maximum with differential pressures not to exceed 1 PSIG. The valve is designed with appropriate clearances in the disc for combustion installations. These applications are typically :"Hot" or "Cold" lines of air or combustible gases that require High-Low or Modulating flow control.
