Belimo butterfly valve range has expanded to include competitively priced assemblies for applications that require 50 psi close-off pressure. These assemblies are identified by the last digit “U” in the valve body nomenclature. Valves sizes 3” to 6” feature HDU bodies for 2-way and 3-way configurations motorized with non-spring return standard actuator series GR, GM, and DR. Valve sizes 8” and 10” sizes feature LU bodies for 2-way configurations motorized with non-spring return PR series actuators.
The HDU and LU series offers a unique seat, and disc design ensures positive valve sealing while maintaining low seating torque. The HDU and LU series provides economical HVAC solutions up to 50 psi close-off.
