1. Flow Capacity:

Consideration must be given to the flow capacity of the interconnect piping between KR Regulators (KR) and the wellhead equipment being operated. Inadequate flow capacity may result in excessive back pressure which can cause the KR to hammer or chatter which is rapid opening and closing as the KR seeks to shutoff at set pressure. Also excessive back pressure will reduce the flow as the KR may not be fully open which will reduce the function time of the equipment being operated.
