The MS-LR-B Pressure Regulating Valve stands out for its 25 mm module width, offering an economical solution with a technical focus. Manufactured with modern polymeric materials, it is lightweight and robust. Integrable with the MS series, it allows for an efficient combination of basic functions at an attractive cost. It promotes stable pressure control, available with or without a pressure gauge, and includes a handle with a retainer, integrated secondary exhaust, and primary exhaust for efficient return flow. Variations include the MS2 with a diaphragm regulating valve and the MS4 and MS6 with a piston valve, all sustainable by reducing the pressure level.
