ENG-93001-93621-08.04-1M • Printed in Switzerland • ZSD • Subject to technical modifications BC 14 H6..N globe valves, 2-way, with flanged ends Applications • Water-side control of air handling units • Water-side control in heating systems Mode of operation The globe valve is operated by an NV or AV series linear actuator. The linear actuators are controlled by a standard modulating or 3-point control system and move the cone of the valve, the throttling device, to the opening position dictated by the control signal. Product features Equal-percentage characteristic Produced by the profiling of the valve cone. Manual operation with NV / AV actuator Using a hexagonal key to turn the actuator. • For installation instructions, refer to pages 30…32 • For closing pressure / differential pressure, refer to page 8 • Sizing diagram for globe valves, refer to page 9 • The information provided on pages 33/34 regarding operation, installation, project design, commissioning and maintenance must be strictly observed.
