The 836T-T253JX145X9 controller is an Allen-Bradley pressure controller which belongs to the 836T product line. The 836T-T253JX145X9 controller is a Style T pressure controller. The 836T product line also includes D-style pressure controls. The difference between Style T and Style D devices is that Style T devices are used for regular pressure control whereas Style D devices are used for pressure difference control. Style T devices feature independently adjustable operating and differential pressure ranges and they come with a single set of bellows or 1 piston. The bellows on the Style T devices can be either made of steel or copper alloy. Devices with steel bellows are suitable for locations containing hazardous and corrosive materials. Devices with copper alloy bellows are suitable for locations which are free of corrosive gases and liquids.

The bellows on the 836T-T253JX145X9 controller are made of copper alloy. The enclosure of this pressure controller is a NEMA Type 1, 4, and 13 enclosure. The pressure specifications for the 836T-T253JX145X9 controller are 12 to 150 PSI for the operating range, 6 to 30 PSI for the differential range, 350 PSI of maximum line pressure, and 450 PSI of occasional surge pressure. The 836T-T253JX145X9 controller has a S.P.D.T 2-circuit contact block. The pressure media which can be used with Style-T devices, including the 836T-T253JX145X9 controller, are air, water, and non-corrosive hydraulic fluids. The standard pressure connection for the 836T-T253JX145X9 controller is a 0.25-inch N.P.T.F. female pipe thread. When ordering a pressure controller, the device style, pressure specifications, enclosure, and pressure connection hardware should all be considered. To prevent equipment damage and injury to the users, the installation of the 836T-T253JX145X9 controller should only be assigned to trained technicians.
