Allen-Bradley 836T-T252J Pressure Control Devices

Allen-Bradley 836T-T252J is an externally adjustable electro-mechanical pressure control in the Bulletin 836T family, designed for traditional machine-tool and rugged industrial applications. Configured as a T-style pressure control, it provides a 75 psi operating range with a maximum line pressure of 200 psi, and an adjustable differential of about 3 psi, enabling precise on/off switching at the target pressure. The device employs copper-alloy bellows and a piston-type actuator, delivering reliable performance under fluctuating process pressures. Its electrical interface is SPDT with a 2-circuit contact block, suitable for simple two-point control schemes; other 836T variants exist with four circuits, but the T252J SKU specifies 2 circuits. The enclosure is rated Type 1, 4 and 13 for industrial environments, and the unit is intended for use in machine tools and other industrial controls where external setpoint adjustment is required. As part of Rockwell Automation’s pressure-control lineup, the 836T-T252J combines robust construction with an externally adjustable setpoint, enabling operators to tailor the control point without opening the instrument enclosure.
