Pressure Control Regulator

The Pressure control regulator is designed to simply and effectively control well fluid pressures on pumping or flowing wells. It is spring loaded to maintain a pre-set pressure. This pressure may range from 0 to 1,500 PSIG (0 to 10.3 MPa). The spring adjustment is located outside the valve body for ease in setting and safety, and the adjusting screw is secured from accidental movement by use of a lock nut.

Operating advantages are:
(1) Decreased paraffin deposits by holding gas in solution;
(2) provides longer life for stuffing box packing by minimizing heading and flowing-off;
(3) provides a longer life to all pumping equipment by maintaining a constant operating load;
(4) decreases the tendency of wells to bridge or sand heave;
(5) Reduces measured GOR which in turn conserves reservoir energy;
(6) Extends bottom hole pump life by the equalizing fluid column and the formation pressures on pump valves.

Far superior to bean and adjustable chokes the Pressure Control Regulator can adjust immediately to fluctuations in well pressure. The spring-loaded action also keeps the valve clean and free from abrasive particles that could cut it out. A Chrome-vanadium spring and an API stainless steel ball and seat are standard equipment, however other grades of balls and seats are available. A 1/4" (6.3mm) tap is provided upstream of the valve so that pressure across the valve may be checked before the valve is serviced. The ball, seat and spring can be removed without disturbing the well head connections. The adjusting screw is sealed with an "O" ring and is manufactured with a "bell style" end so that it can not be unscrewed when the regulator is under pressure. The forged steel body is available in either a tee or cross. Springs are available with the following settings: 0-250#, 0-500#, 0-1,000#, and 0-1,500#. The regulator body pressure is rated at 2,000 lbs.
