Bonetti's CMI line production range consists of 3 sections:

  • Gate Valves, Globe Valves

  • Stop, Stop-Check, Piston Lift Check

  • Swing and Tilting Disk Check Valves

All valves in this series are suitable for high pressures and temperatures. Swing and Tilting Disk Check Valves are also for applications at ambient and/or very low temperature conditions. The main technical features of these valves have been proven and optimized by Bonetti over 50 years of experience in severe power generation applications such as boiler feed water and steam shut off against back flow, as well as in chemical and petrochemical plants.
CMI Globe Valves

CMI Globe Valves perform the following functions: Stop on-off shut to fluid flow, Stop and throttle-when a parabolic shaped disk is used in lieu of a standard stop disk. A linear flow characteristic is achieved as a direct function of the stem turns, Stop check-both a stop and a non-return valve and Piston lift check-for automatic prevention of undesired reverse flow.

Quick Acting Automatic 2 and 3 Way Valves  - CMI Series

Quick Acting automatic 2 and 3 way valves for H.P. Pre-heaters bypass systems are valves that are hydraulic self-actuated by means of an integral piston whose speed is controlled by an external regulating valve. Meeting ASME Class 900 thru 2500, and special classes. Available in sizes up to 18".

These automatic by-pass valves are typically installed on the condensate or feedwater lines of thermal power stations. They are designed to automatically intercept fluid flow to the HP feed water preheater in case of a high water level condition in the preheater shell.
 
Typical connections are butt weld ends (BW) as per ASME B16.25. Other connections are available on request.

Ratings and Sizes:

  • ASME Class 900 (PN 150) Standard Class or Special Class - Sizes 3" to 16" (DN 80 to 400)
  • ASME Class 1500 (PN 250) Standard Class or Special Class - Sizes 3" to 16" (DN 80 to 400)
  • ASME Class 2500 (PN 420) Standard Class or Special Class - Sizes 3" to 16" (DN 80 to 400)

The body material is a high quality casting. The selection of the construction materials of other components is based on the actual operating requirements to insure the best combination for physical and mechanical stability under high pressure and temperature conditions.

CMI Pasquini Power Actuated Check Valves with Pneumatic Actuator

 

Swing Disk Type - Testable Valves
These special types of swing-disk check valves are usually installed on the turbine steam bleeding lines of the feedwater preheating stages of modern power station cycles. The main function is the quick shut off of the bleeding steam pipes in case of loss of turbine load to prevent the dangerous water carryover from the preheater back to the turbine. In the upset or emergency condition of the turbine, the compressed air is vented, the spring is free to extend inside the cylinder and the actuator piston rotates the valve disk to intercept the steam bleeding pipe. The main function of the spring is to overrun the starting friction on the packing and pivot bearings.

These swing type disk check valves are usually manufactured to the ratings and sizing of:

  • ASME Class 150 Bolted Bonnet - Sizes 4" to 42" (DN 100 to 1050)
  • ASME Class 300 Bolted Bonnet - Sizes 4" to 42" (DN 100 to 1050)

  • ASME Class 600 Bolted Bonnet - Sizes 4" to 16" (DN 100 to 400)
  • ASME Class 1500 Pressure Seal Bonnet - Sizes 4" to 12" (DN 100 to 300)
  • ASME Class 2500 (PN 420) Pressure Seal Bonnet - Sizes 4" to 8" (DN 100 to 200)
