Pneumatic/Motorized Check Valve
High-performance automated check valves engineered to prevent backflow and protect critical process equipment across oil & gas, petrochemical, power, and industrial applications.
Pneumatic & Motorized Check Valves - Automated Backflow Prevention
Pneumatic and motorized check valves provide reliable automatic non-return flow control, preventing reverse flow to protect pumps, pipelines, and process equipment. Compatible with pneumatic and electric actuators, these valves are manufactured to BS 1868, ASME B16.34, and API 6D standards. Covering sizes from 1/2`` (DN15) to 24`` (DN600) across ANSI Class 150 to 600 and PN 10 to PN 100 ratings, they support flanged and butt weld end connections. Fully compatible with PLC, DCS, and SCADA systems for remote monitoring and automated process control.
