The pressure controlling station ZGV 3/4 is a single or dual-stage pressure controlling station with a self-acting switch.
It’s main purpose is the ensured withdrawal of gases and gas mixtures from gas cylinders. The self-acting function of a two-stage station is activated as soon as the pressure on the primary stage descends below a preset value.

The pressure reduction is controlled by two integrated pressure control regulators conected by their outlet openings. This enables an
exchange of gas cylinders without an interruption of gas supply.
The station is mounted on a stainless steel panel and possesses as standard an inlet and an outlet gauge as well as an relief valve and
a cut-off valve for the process gas + filter.

Especially for gases with safety and impermeability requirements, as well as for the assurance of an uninterrupted gas supply overnight and during the weekends.
An enhancement of the gas supplying concept is achieved by an optional integration of a gauge and a gas leakage warning device.
