Project Description
Model JA
Model JA
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.
Model JA
Set Pressure: 25-3,750 Psi
Accuracy: + / – 5%.
Connections: Standard flange connections available.
Seals: Available for high & low temperatures, viton standard.
Standard Materials: Body mild steel with stainless steel trim, other materials optional.
Product Feature
This fully mechanical emergency shutoff valve eliminates the need to have electricity or pneumatics on site.
Applications
The Model J-A isolation valve closes at set pressure to prevent damage to downstream equipment from excess pressure including meter houses and line transitions.
