E-Valve

The Equalization Exhaust Valve (“E” Valve for short) is placed inside the casing below the well seal but above the highest anticipated liquid level. The valve allows the high-pressure pump exhaust to be released into the atmosphere and allows the low-pressure exhaust to be equalized to the partial vacuum in the wellbore via the small 0.031″ orifice hole. The liquid level that can be achieved in the well would be the normal pump activation level, approximately 10 inches below the top of the SRX pump’s head. There is also only one moving part and there is no operator adjustment.
