Pressure Regulation (HPRT)
HPRT series units are systems designed for reduction and regulation of gas pressure; the units are assembled and tested in the factory to guarantee the maximum safety in operation and an easy installation. HPRT are designed to be integrated in high pressure systems and used when it is necessary to regulate gas pressure available in the line to obtain values compatible with the application. Pressure regulating/reducing units are integrating part of the burner and together they compose a single system for gas combustion. HPRT pressure regulating/reducing units are equipped with a shut-off ball valve and a filter for a preliminary treatment of inlet gas. Pressure regulators installed on HPRT series units are direct action devices, controlled by a diaphragm and counterspring. A safety slam-shut valve is included in the supply; this device blocks gas flow when the downstream pressure is modified (increased or decreased) up to the
intervention set-point; alternatively, it can be actuated manually. HPRT units include a pressure relief valve, a device mounted to avoid that small leaks (when there is no flow required) or sudden and temporary overpressures (such as deriving from rapid switching or overheating of the gas) cause intervention of the slam shut. Pressure gauges with shut-off cock are mounted upstream or downstream to the regulator, allowing pressure monitoring. An antivibrating joint permits to damp vibrations and a simple connection to the gas distribution circuit.
