The E-4™ wireline pressure setting assembly (W.L.P.S.A.) is a device in which the products of combustion are utilized for the gradual development of force through pressure. This motive force operates the various working parts of the W.L.P.S.A. in a proper sequence to ensure the successful setting of Baker Hughes bridge plugs, retainer production packers, cement retainers, and other products.

The pressure required is built up through a slow-set power charge, (Product Family No. H43766), or a standard power charge, (Product Family No. H43764). For specifics on all power charges and igniters view our Slow-Set Power Charge, Standard Power Charge, Secondary Igniter, BP-3S and BP-4S Igniter product pages (Product Family Nos. H43766, H43764, H43743, H43744).

The setting pressure is confined to the proper area of the setting tool through the use of O-ring seals. It is of critical importance that all O-rings be maintained in perfect condition and replaced after each use.

The E-4 wireline pressure setting assembly incorporates a piercing disk bleeder system to provide a safe, easy method of bleeding off trapped pressure before disassembling the W.L.P.S.A. after it has been run.
