SBEM’s Magnetic Float Type Side Mounted Pneumatic Control Series 137 PNP is a high-precision level measurement and control solution designed for industrial process automation worldwide. This compact pneumatic controller delivers output pressure proportional to liquid level directly or inversely based on control action, ideal for actuating pneumatic valves, dampers, and other equipment. Engineered for durability and performance, it supports working pressures up to 40 Kg/cm², operating temperatures from 0°C to 300°C, and liquid densities ranging from 0.8 to 1.2 Kg/dm³. Constructed with SS316 wet parts and an aluminium alloy enclosure, the 137 PNP ensures longevity in harsh environments. With flexible output (0.2–1.0 Kg/cm² or 3–15 PSI), various flange types (SS316, CS, SS304, ASTM A105), and options for float extension, it meets global industrial standards. Its magnetic float technology guarantees accurate level tracking and responsive pneumatic control, making it ideal for chemical, petrochemical, and power plant applications. SBEM ensures reliable performance backed by ISO 9001:2008 certification.
