Brannan AOP040 | Over Pressure Protector | 1 to 400 bar adjustable
The Brannan AOP040 over pressure protector shields pressure instruments from sudden pressure changes and surges. When the preset pressure is exceeded it automatically shuts off pressure to the instrument, and it reopens only once pressure falls back below a set value. Adjustable ranges run from 1 to 400 bar, and each unit is built to the customer's specification of wetted material, connection and range for oil and gas, chemical and petrochemical, and water and wastewater duty.
