Description

Bulletin 836T Pressure Controls are control circuit devices designed to meet the traditional requirements of the transportation, machine tool, and other heavy-duty industries. Allen-Bradley Bulletin 836T Pressure Controls can be used in pneumatic and hydraulic applications. The copper alloy bellows actuators can be used with air, water, oil, vapor, and other non-corrosive gases and liquids. Type 316 stainless steel bellows are available for more corrosive gases, vapors, and fluids.

A rugged stainless steel cylinder and stainless steel piston assembly is used for the higher-pressure coolant and hydraulic oil applications. May also be used with water and water-based fluids. The controls feature snap-action precision switches equipped with silver contacts. A relatively friction-free mechanism provides consistent operation regardless of mounting position. Devices are designed to allow easy adjustment of pressure settings.

Allen-Bradley Bulletin 836T Pressure Controls are used in many types of applications with adjustable ranges from 30 in. Hg vacuum…5000 psi. They can be used to control pneumatic systems and maintain a pressure tank within a preset and constant pressure range. They can be used to detect over-pressures of gases and liquids to prevent damage to valuable equipment. Pressure controls can also detect low pressure to protect equipment from loss of coolants and lubrication.

Bulletin 836T Pressure Controls are offered in a variety of styles to fit a wide range of applications. The devices are available with either a Type 1, 4 & 13, or 7 & 9 and 4 & 13 combined enclosure. They are available with two-circuit or four-circuit contact blocks. Accessories and modifications are available to tailor the devices to meet most application requirements.
