Hung-Cage Construction
A unique hung-cage throttling design eliminates gasket damage and bonnet or seat leaks due to thermal expansion. Anti-cavitation (Les-Cav) and low-noise (Les-Sonic) cages are available for special application needs. Cages and trim material are 400 series stainless steel with optional Stellite® hardfacing available. Standard valve packing is braided Teflon® graphite. Teflon® chevron and graphite type II is optional for higher temperature service.
Easy Maintenance
The cage trim is easy to remove for inspection or replacement. There are no welded, screwed-in or press-fit parts. Capacity changes are achieved simply by replacing the cage. There's no need to replace any other parts or add any adapters.
