The device provides pressure reduction from high to low and automatic maintenance of the set outlet pressure regardless of changes in gas flow rate and inlet pressure. Series "Dival 500" - a combined regulator with an internal or external pulse, which includes a safety relief valve and a safety shut-off valve
The Norval pressure regulator is designed to regulate the pressure of pre-purified gases. This device belongs to the type of normally open regulators, that is, to devices that open in emergency situations: rupture of the main diaphragm and no signal for pressure regulation.
Pilot pressure regulator PN 1.6 MPa. Designed for the reduction of pre-purified non-aggressive gas. It belongs to the type of normally closed regulators, i.e. closing in the following cases: rupture of the main diaphragm, rupture of the pilot diaphragm, lack of gas supply in the pilot circuit.
