The Allen-Bradley 836T-T253JX40 controller is a T-Style pressure controller. The 836T-T253JX40 controller belongs to the Bulletin 836T pressure controller product line which includes devices featuring 2 and 4-circuit contact blocks, adjustable differential and operating pressure ranges, multiple enclosure types, and steel and copper bellows. The 836T-T253JX40 controller is a 4-circuit device which features a D.P.D.T contact block. The enclosure of the 836T-T253JX40 controller is a Type 1, 4, and 13 enclosure which is specially designed for industrial use. The bellows on the controller are made of copper alloy. The adjustable operating pressure range of the 836T-T253JX40 controller is from 12 to 150 PSI. The adjustable differential pressure range of the 836T-T253JX40 controller (mid-range values) is 9 to 30 PSI. The maximum line pressure rating for the 836T-T253JX40 controller is 350 PSI. A pilot light is not available on the controller.

The Allen-Bradley 836T-T253JX40 controller is an electro-mechanical controller which is also oil tight. The temperature range recommended for the operation of the 836T-T253JX40 controller is from -30 to 66 degrees Celsius. The temperature range recommended for the storage of the 836T-T253JX40 controller is from -30 to 93 degrees Celsius. Industrial applications for which Bulletin 836T controllers are designed include material clamping, air compressors, lubricant pressures, coolant pressures, and machine tools applications. Bulletin 836T controllers can be used in hydraulic and pneumatic applications. Copper alloy bellows can be used with oil, vapor, air, and other types of non-corrosive substances. Controllers with stainless steel bellows can be used with corrosive gases and fluids. Bulletin 836T controls can also be used to protect equipment from loss of lubrication and coolant fluids.
