Model A ESV Overview
The Model A is an angle body valve that stays open in normal flow and closes for a bubble-tight seal at set point. If a downstream line breaks, the flow itself drives the valve closed.
Key features
- Closes on a downstream line break
- Keeps you from flaring or venting production to the atmosphere
- Standard 2 in NPT and custom connections
- Pin color matches the holding nut color to help confirm the set pressure
- Optional proximity sensor for remote closed indication
Common applications
- Protecting meter runs from excess pressure
- Keeping well pressure within D.O.T. transmission limits
- Meter houses
- Line transitions
