Cage Ball Control Valve Model Lowcav/Lownoise

LOWCAV and LOWNOISE X-TRIM Cage valves are engineered for those services where is required pressure and flow rate control with reduced cavitation and noise issues.


Cage Valves model LOWCAV and LOWNOISE are mainly suitable for liquid, steam and gas applications in standard and severe services (with low/cryogenic and high temperature). A dedicated designed X-TRIM is optimized for cavitation control (LOWCAV) and noise reduction (LOWNOISE) with very high rangeability and high FL values in throttling service. X-TRIM design for extreme applications!


  • Low Temperature and Low Alloy Carbon Steel
  • Stainless steel, Duplex and Super Duplex
