Butterfly Valve Assembly Product Update

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.

• 3” to 6” sizes feature HDU bodies for 2-way and 3-way configurations motorized with non-spring return standard actuator series GR, GM, and DR.
• 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 cartridge style seat incorporates an elastomer bonded to a phenolic stabilizing ring, eliminating elastomer movement and reducing seat tearing or fatiguing due to bunching. The HDU and LU series provides economical HVAC solutions up to 50 psi close-off.
