water butterfly valve elephant wbv3131e 2w fb h wafer body stainless steel 304 disk stainless steel 304 epdm with pneumatic drive pa da 105 1 with pneumatic distributor 4v320 08 220v lsu apl 410n ex atu afc2000 Stainless Steel Ball Valve The positioner uses a nozzle-flap

The positioner uses a nozzle-flap device and a feedback servo mechanism (a system of springs and levers) to bring the control force and the feedback force into equilibrium when the pneumatic actuator (valve) reaches the position corresponding to the control signal

it becomes possible to transmit information about the position of the pipeline valve (open / closed) to automated control systems

Une extrémité du ressort est fixée à l'intérieur de la tige et l'autre extrémité est reliée à l'axe de la flèche
