MUST
be installed by a certified welder only. +GF+ SIGNET will not assume liability of any kind for improper
fitting installations.
•
The 2540 Hot-Tap system's overall specifications and limitations depend on the lowest maximum rating of the components
associated with the system. In other words, the Hot-Tap system is only as strong as its weakest link. For example, a ball
valve, a component of the system, is rated at a maximum 100 psi @ 175
°
F, limiting the entire system's maximum pressure/
temperature rating to 100 psi @ 175
°
F. All higher maximum specifications
MUST
yield to the component with the lowest
maximum specification.
Maximum Operating Pressure/Temperature:
• 17 bar (250 psi) @ 82
°
C (180
°
F) with standard Viton® sensor fitting O-rings.
• 17 bar (250 psi) @ 100
°

F) with optional EPR sensor fitting O-rings.
