The Allen-Bradley 836T-T351JX3 controller is a pressure controller with adjustable trip/reset settings. It is shipped from the factory with its operating pressure set to the maximum setting and differential pressure set to the minimum setting. For the Allen-Bradley 836T-T351JX3 pressure controller, the operating pressure range is from 140 to 1000 PSI and the adjustable differential pressure range on the controller is 100 to 175 PSI. The 836T-T351JX3 controller is designed to be able to handle an occasional surge pressure of up to 10,000 PSI. The actuator type on the 836T-T351JX3 controller is a piston with a seal. The external differential pressure adjustment screw is sealed on this controller and the cover must be removed for the adjustment of the differential (including the contact block shield). The 836T-T351JX3 controller is a Style T 836T pressure controller in a NEMA Type 1, 4, and 13 enclosure.

A hydraulic fluid return mechanism to return fluid to the reservoir is not required on the Allen-Bradley 836T-T351JX3 pressure controller. The controller is based on a 2-circuit SPDT type of contact block. The repeat accuracy of the control is +/-5%. The 836T series controllers are designed for typical repeat accuracy which is based on a percentage of the maximum range, evaluated from field tests, and calculated using formulas defined in the ICS 2-225 standards. Applications where the contacts remain within 30 to 80% of the operating pressure range and where the line pressure and occasional surge pressure do not exceed rated values will provide reliable long-term operation and repeat accuracy. The recommended operating and storage temperature ranges for the controller are -30 to 66 degrees Celsius and -30 to 93 degrees Celsius, respectively.
