Belimo Control Valves & Valve Assemblies

CONTROL VALVES

  • Pressure independent valves compensate for pressure variations, performing a continual balancing function to maintain system performance at varying loads.
  • Predictable flow throughout valve travel eliminates over-pumping and provides favorable energy savings.
  • Equal percentage flow characteristic leads to system controllability.
  • PICCV and ePIV prevent energizing additional chillers by maintaining desirable Delta T.
  • CCV and HTCCV offers Cv values equal to globe valves of the same size requiring no additional system design.
  • Valve bodies available with stainless steel trim or chrome plated brass trim depending upon application and cost involved.
  • Higher close-off rating ensures shut off.

Applications

Pressure independent valves directly control the water flow required by the coil and are not affected by pressure fluctuations in the system. The valves are selected based on the GPM requirements of the coil and no Cv calculations are needed. By precisely controlling the flow, the Pressure Independent valves eliminate the need for balancing valves, thus reducing the installation and balancing cost. By far, the biggest benefit for the owner comes in the form of energy savings by eliminating overflow thru the coil. Overflow wastes energy by over pumping and is the main cause of the low Delta T syndrome in chilled water systems.

Characterized Control Valve (CCV and High Temperature CCV) marks a true advancement in control valves. It combines the high close-off capabilities of a ball valve with a specialized disc that ensures a true equal percentage flow characteristic. Both the HTCCV and CCV are available with spring return and non-spring return actuators.

The comprehensive line of globe valves, butterfly valves and ball vales are available in a variety of sizes and fulfills the requirements of many HVAC applications. Valves are fitted with either spring or non-spring return actuators, globe valves are the perfect fit for such applications as unit ventilation and air handling units as well as other water/steam control in heating and cooling systems. Butterfly valves fullfills the requirement of commercial and industrial HVAC applications requiring positive shutoff for liquids, applications include chiller isolation, cooling tower isolation, change-over systems, large air handler coil control and bypass including related process control.
