General

Differential pressure regulators are designed to stabilize vacuum. They are used in gas chlorine installations, with minor alterations they can also be used for other gases. They are made of the best and most resistant materials. The springs are made of tantalum alloys, housing from special ABS plastic or rigid massive PVC, the diaphragms, O-rings, gaskets and washers are made of quality materials like ECTFE foil, FPM/FKM, PTFE (TEFLON), PVDF, which all ensures faultless operation of these devices at high mechanical and temperature load.

Operation principle

The return pressure acts upon the underside of the diaphragm.

The diaphragm along with the spring act together to react to system changes and to keep this constant pressure (vacuum) loss.

As the system pressure (vacuum) rises, the diaphragm moves the valve cone down, to keep a controlled circuit pressure.
