Model JA-SIL-3 Capable

The Model JA -SIL-3 Capable 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.

Set Pressure: 25 – 1,480 Psi
Accuracy: + / – 5%
Connections: Flange rating 150#, 300# and 600# standard. Higher pressure available upon request.
Seals: Available for high & low temperatures, Viton standard.
Standard Materials: Carbon steel body with stainless-steel trim, other materials optional.

The Model J-A SIL 3 Capable isolation valve closes at set pressure to prevent damage to downstream equipment from excess pressure including meter houses and line transitions.
SIL, or Safety Integrity Level, is a measurement scale of safety system performance for an element with safety instrumented function (SIF) installed in a safety instrumented system (SIS). There are four possible ratings: 1, 2, 3 and 4; the higher the rating, the more functionally safe the system is deemed to be based upon specified risk factors prescribed by IEC 61508 guidelines.

When installing three SIL capable J-A ESVs in a system, a Safety Integrity Level of 3 is achieved with a risk reduction factor of 10,000 to 1,000.
