Description & Features
CV2900 Labyrinth trim control valve prevents the damaging effects of noise and erosion typically associated with severe service applications, as high pressure drop conditions and the potential for fluid to develop high velocities when passing through the control element. In some cases, process temperature contributes to severe service conditions.
Multi stage stacked disk trim designed with constant area rations that provide a torturous path controlled pressure drop at each stage. Use of this design totally precludes the high velocity in compressible flow that creates noise or the critical pressure drops in flow that creates cavitation.
Prevent cavitation, zero stem leakage, have safe and long life.
Trim permits quick disassembly and easy maintenance, reliability and reduced maintenance costs by preventing cavitation, erosion, noise, and vibration.
Wear resistance and prevent trim sticking or galling by advanced design and technology, high grade material and fine pairing.
Noise reduction more effectively than competitors’ similar product.
