Cage Ball Control Valve model LOWCAV / LOWNOISE

Cage Ball Control Valve model LOWCAV / LOWNOISE

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 trim is optimized for cavitation control (LOWCAV) and noise reduction (LOWNOISE) with very high rangeability and high FL values in throttling service.

Sealing: Only for Bi-directional : Double block & bleed (DBB) with sealing in both directions (DIB-1&2 upon request). Metal seated with Tungsten or Chrome Carbide coatings Primary metal secondary soft (PMSS) with differential hardness between the ball and seat to prevent galling of the substrate

Material testing: Pressure containing & controlling parts to EN 10204 3.1;
Materials in Sour Service according to NACE MR0175, MR0103, ISO 15156;
Non-destructive testing (NDT) to API 6D, ASME B16.34
