Description

New, patent pending Q-Disc™ design features outstanding flow balancing performances for control service on Neldisc™ high performance butterfly valves. Dynamic torque effect from the flow has been significantly reduced allowing high pressure drop service. Design also provides market leading noise reduction even up to 12 dB.

A simple but effective design enables balanced flow without affecting valve performance. The design is suitable for all available body types and face-to-face lengths and with a wide temperature range (up to +600 °C) which makes Q-Disc™ the most versatile flow balancer on the market.

Q-Disc™ is designed to balance the torque effect caused by the flow. In standard offset designs, flow causes dynamic torque effect caused by uneven pressure across the disc surface. With Q-Disc™, the pressure is distributed more evenly resulting in lower torque requirement and more effective control of flow.
