The WNS Lowery Series W770 Back Pressure Regulator (BPR) offers an affordable solution for maintaining a constant back pressure and an automatic relief of pressure in liquid or gas applications. By maintaining a constant and reliable back pressure on the oil column, this valve ensures gas bubbles do not break out of solution and reduces the paraffin build up in the well. The decrease of gas pockets in the oil also provides a continuous lubrication of the polished rod, extending the life of the stuffing box cone packing, while also enhancing the efficiency of the bottom hole pump.
