Why customers like Inferno gage valves…
A Viton O-ring is provided in the vessel union for easier fit-up in the field. This can insure no leakage at the union providing angular misalignments are reasonable
The standard, most popular vessel connection is designed with a narrowed neck on the shank and an undercut in the union nut. The combination permits ± 1/8” movement of the shank around the face of the valve body in all directions. This translates into adjustability of C-C of ± 1/4”, one-third more than our nearest competitor
Conforms to NACE MR0175: "Free-Turn” design offers a longer service life compared to older style, conventional gage valves
Patented Design: “Packing below the threads” isolates the valve workings from the process….Ensures low operating torque…. Especially suited for brine and sour gas
Offset Pattern: Permits clean-out using brush
Automatic Safety Ball Checks: Provide rapid shut-off of process fluid in the event of a sudden pressure drop due to glass failure or seal blow-out
