Neles™ Q-Disc™ flow balancing trim for Neldisc™ butterfly valves
The Q-Disc design, currently pending a patent, incorporates extreme flow balancing to enhance its control service capabilities. This innovative design effectively reduces the dynamic torque effect caused by flow, making it suitable for high-pressure drop services. Additionally, the Q-Disc design leads the market in noise reduction, achieving up to 12 dB reduction.
Design
The Q-Disc is specifically engineered to counteract the torque effect generated by the flow in standard offset designs, which is caused by uneven pressure across the disc surface.
By distributing pressure more uniformly, the Q-Disc reduces the required torque and enhances flow control efficiency.
