Product Overview
The Siemens VAI61.40-16 / GMA131.9E is a complete industrial ball valve assembly with a factory-matched quarter-turn electric actuator, engineered for precise on/off and modulating control of process media in demanding plant environments. The valve body is a flanged ball valve with a nominal bore of DN40 (1½”) and a PN16 pressure rating, providing full-bore, low-torque shutoff with minimal pressure drop across the flow path. The GMA131.9E actuator is a compact, high-torque electric actuator designed for direct-mounted quarter-turn operation, delivering reliable 90° rotation with mechanical position indication and end-position feedback. This assembly is widely deployed as a drop-in control element in building services, district heating, water treatment, and general industrial process lines where dependable isolation and repeatable positioning are essential.
