Pressure Regulators – Proteu

Pressure Regulators - Proteu

The PROTEU N series is a self operated pressure regulating valve with direct spring action, which project allows industrial applications with high flow and intermediary pressure. It is ideal to be used such in Natural Gas, LPG and Nitrogen, beyond other non corrosive gases. The construction option with body material in Forged Brass allows to apply the regulator with Oxygen.

The regulation accuracy for large range flow is a characteristic of PROTEU N series. In case of gas consumption ausence the regulator closes with zero leakage.

The simplicity in operation procedure is due robust design and totally trustful, becoming the maintenance service quick and easy. The “top-entry” design allows to inspect seat and obtuator and it is not necessary to take the body out of line.
