VFB Butterfly Valves

DN25...500, PN16

VFB butterfly valves series are specifically designed for a wide range of Heating, Ventilating, and Air Conditioning (HVAC) applications, including two-position and modulating control of hot, chilled, or condenser water, and 50/50 glycol solutions. All valves are factory tested for bubble-tight shutoff at 100% of the fully-rated pressure. These valves are also bidirectional, allowing positive shutoff with the flow in either direction.

Features

  • Low seating/unseating torques Reduce actuator torque and size requirements, particularly with lower-pressure rated valves
  • Bubble-tight shutoff Ensures positive closure when needed
  • Broad range of pre-assembled actuators. Offers a wide selection for new and replacement electric and pneumatic actuators
  • High-Integrity Components Provide quality valve assemblies, combining long cycle life with optimal engineered functional designs
  • Fluid Temperature Limits -29 °C to 121 °C
  • Flow Characteristics Modified Equal Percentage
