The Siemens 2 way brass ball valves are available from ½ thru 2 inches size NPT connections.
They are ideal for flow control of hot or chilled water in HVAC applications and have a minimum close-off of 200 psi.
Their universal mounting plate allows simple assembly with commercially available on/off or proportional 24VAC/VDC actuators.
Each valve size has multiple cv values which help to achieve precise control and equal percentage characteristics that results in linear heat transfer to maximize temperature control.
Full port options are also available when isolation requirements are specified.
Belimo damper actuators are easily mounted with VSI’s damper linkages.
These actuators are available in 24VAC, 120V or 220V, modulating or floating service as well as spring return or non-spring return.
Belimo offers a fail-safe version of larger damper actuators. Fail-safe actuators are a cost-effective alternative to mechanical spring return.
Please contact a VSI representative for additional options.
