Dual Range Vacuum & Pressure Regulator


Regulation of both vacuum and positive pressures. Built with a dual range pressure transducer capable of accurately measuring pressures from full vacuum to the pressure limit of the transducer selected. The maximum pressure of the controller is user selectable. Contains an absolute pressure transducer.

Select maximum pressure range.

Select two valves, one for vacuum and one for pressure regulation.

The optimal PSV value depends on the exact conditions of the procedure. The table below applies to closed systems. For applications with a continuous purge of gas, call J-KEM for assistance.
