Model JA SIL 3 Rated

Model JA SIL 3 Rated

The Model JA is an inline valve that holds a bubble-tight, open position until flowing pressure acting on the unbalanced stem area puts an axial force on the pin. At set point, the pin buckles and the valve closes for a bubble-tight seal. This model isolates pressure to prevent downstream damage to equipment and proves it is environmentally friendly by eliminating air and ground pollution common with conventional relief valves.
