Anderson Greenwood M4TL Liquid LeveL ManifoLds
Bonnet AsseMBly options
The 4TL has metal seats as standard with the
option of soft seated designs.
all stem threads are rolled and lubricated to
prevent galling and reduce operating torque.
The stem seal is a patented PTfe packing
gland which is adjustable in service. all bonnets
are assembled with a bonnet locking pin to
prevent accidental removal while in service
and a protective dust cap is fitted to contain
stem lubricant and prevent the influx of
contaminants.
Metal-seated bonnet assemblies
The metal-seated bonnet assemblies have a
rotating stem with free swivel ball-type seat for
long service life. The specially hardened ball
seat is ideal for both gas and liquid service.
soft-seated bonnet assemblies
The soft-seated bonnet assemblies have a
one-piece rotating stem and plug. in addition to
the adjustable PTfe packing gland, the bonnets
are available with a fKM o-ring and PTfe
back-up ring.
