The 836-C64E pressure controller is an electromechanical pressure control device manufactured by Allen-Bradley as part of the Bulletin 836 Pressure Controls device series. It does not support factory modifications such as the single pole, double throw, and snap action modifications available in other pressure controllers. This unit is a Style C pressure controller with a Type 7 & 9 and 4 & 13 aluminum enclosure type for protection. The Allen-Bradley 836-C64E electromechanical pressure controller has an adjustable differential pressure range of 4 to 45 PSI, and an adjustable operating pressure range of 6 to 250 PSI. Other notable features of this pressure control switch include maximum line pressure of 450 PSI and a maximum occasional surge pressure rating of 450 PSI. It also features stainless steel external bellows that can resist corrosion.

The Bulletin 836 Pressure Controls series switches like the Allen-Bradley 836-C64E pressure controller are designed for general industrial use, especially in the control and detection of pressure levels in different systems and applications for system and user safety. This 836 Pressure Controls series device can be used in pneumatic pressure systems as well as hydraulic pressure systems. The 836-C64E pressure controller is made with high-quality components that provides long lasting operation with noncorrosive liquids, gases, air, vapors, water, oil, as well as with certain corrosive liquids and gases. Additionally, the 836-C64E pressure controller has a relatively friction-free and straight in-line construction that offers consistent and accurate operation irrespective of the angle at which it is mounted in the system, which allows for flexibility in the mounting of the controller.
