Barksdale Pressure Regulator S20517 Series Manual Model: S20517 Air Motor Operated: SF20517 Hydraulic Motor Operated: SG20517
Barksdale S20517 series pressure regulators are sensitive pressure-control devices used to maintain a predetermined pressure in a hydraulic circuit. The regulated output pressure is controlled by adjusting spring force by air or hydraulic motor or manually to balance hydraulic loading, and the regulator works on Shear-Seal technology using fluid pressure to maintain a leak-free metal-to-metal seal.
This manual covers safety information, technical data and product configuration, overall dimensions, installation, operation, troubleshooting, maintenance and repair, transport and storage, disposal and returns, nameplate, and warranty. It states that specifications are provided on the catalog or sales drawing supplied with the product and that the regulator should be installed by a trained service person with a media filter in the system.

Loosen the locking handle, then rotate the adjusting handle clockwise to increase pressure or counter-clockwise to decrease pressure, and tighten the locking handle afterward.
The air motor pilot pressure range is 80-120 PSI (5.5-8.3 bar).
The hydraulic motor pilot pressure range is 400-1600 PSI (27.6-110.3 bar).
Isolate the regulator from all system pressure before performing any service procedures.
Yes, it can be installed horizontally or vertically using the mounting holes.
