CONNECTIONS
Bonetti’s “CMI” valves illustrated in this catalogue have the
following
pipe connections:
- Flanged ends according to ASME B16.5 (usually for Class
600 only, not for higher pressure Classes) or to different
Standards;
- Butt weld ends in accordance to ASME B16.25. (See pages
30 and 31 for different standards.).
We can supply valves with connections as needed.
OPERATIONS
Bonetti’s “CMI” valves described in this catalogue perform the
following functions:
- Stop on-off shut off to fluid flow;
- Stop and throttle - when a parabolic shaped disk is used in
lieu of a standard stop disk. A linear flow control characteristic
is achieved as a direct function of the stem turns;
- Stop check - both a stop and a non-return valve;
- Piston lift check - for automatic prevention of undesired
reverse flow.
