2. Deadband (DB):
- STATIC DEADBAND is when the KR is at set pressure and a small fluctuation in outlet is caused by a downstream leak, temperature variation or wellbore packer compression. The Static DB is the difference between the lowest outlet pressure before resetting and the pressure that the KR resets to.
- DYNAMIC DEADBAND is the difference between initial set pressure and the pressure that the KR resets to, after the open flow condition.
3. Set Pressure Adjustment:
When changing (adjusting) the set pressure on a spring operator the outlet needs to be opened and closed briefly a few times to allow the operator and pressure to stabilize. This can be achieved by operating a manifold control valve or installing a separate much smaller valve directly on the outlet line near the KR.
4. Series Installation:
It is NOT recommended to install KR's in series (I.E. do NOT connect the outlet of one KR to the inlet of another). Call our technical support team for the most effective application and installation strategies.
