Back Pressure Regulator (BPR)

Application

The Back Pressure Regulator is an excellent and eco- nomical device for automatic relief of pressure in liquid service. It is actuated by the static upstream pressure, which causes the valve to open at set pressures. The degree of opening will vary and increase in proportion to the increase in pressure over the opening pressure.

The Back Pressure Regulator is offered in a 2” size. The 2” is suitable for pressure settings up to 1500 psi.

Recommended for a variety of oil and gas production applications, including the following:

Paraffin:

A common cause of paraffin build-up is gas breaking out of solu- tion in the tubing string. Through use of this regulator, constant pressure can be maintained on the oil column, permitting gas bub- bles to be pumped out of the string before they rupture and break out of solution.

Heading up:

This regulator, installed on wells that tend to head up and flow, will assure a full tubing string by maintaining constant pressure on the oil column. This assures continuous lubrication of the polish rod, adding to the life of the stuffing box rubbers. This also enhances efficiency of the bottom hole pump.

By-Pass to Casing:

This regulator can also be used as a by-pass to the casing in event lead lines should freeze or get plugged.

Other Uses:

For LACT units to assure full-line operation and for safety relief on separators or casing.
