Allen-Bradley manufactures the 836-C65J pressure controller as an electromechanical pressure controller and as a member of the Bulletin 836 Pressure Controls device family. This pressure controller has been specially engineered for general industrial systems to detect and control pressure levels. The Allen-Bradley Bulletin 836 controller is utilized in the hydraulic and pneumatic pressure systems. The 836-C65J pressure control unit is a Style C pressure control unit which has external bellows made of stainless steel. It also has a pressure specification of 65 and it supports the NEMA Type 4 and 13 aluminum enclosure for protection. It features a special design as well as durable components which offer long-lasting operation with the water, air, oil, and noncorrosive gases and liquids as well as some substances that are corrosive.

The Allen-Bradley 836-C65J pressure controller comes with an adjustable operating pressure range from 35 to 375 PSI and with an adjustable differential pressure range from 8 to 80 PSI. Both of these pressure ranges are independently adjustable and they can be adjusted by using the corresponding screws on the outside of the controller. The line pressure rating and the occasional surge pressure rating for this controller are both 650 PSI at the maximum. Some of the main features of the 836-C65J pressure control device include a contact block, a differential pressure reference scale, an operating pressure range adjustment screw and an external bellows connection mechanism. Other parts of this device are a mounting bracket, a trip indicating scale, a nameplate with the pressure and external rating information, as well as a clear protective contact inspection cover.
