Buckling Pin Technology's new Model J-B and J-A low-high emergency shut-off valve (ESV) system is a combination useful to isolate the upstream flow by sensing upstream pressure. The low pressure ESV closes when a downstream line break occurs.
The high pressure ESV closes at set pressure to protect downstream equipment from excess pressure. The valve combination features simplicity, reliability, setting accuracy and advanced system protection.
This system can be pigged.
