2. General product information
2.1 General description
The full bore two-piece body ball valves that are covered in this document have a floating ball as standard
and are produced in accordance with API 6D. They have been designed for use as isolating valves, not
control valves.
ISO mounting
As standard, all the valves in this document have an integral ISO body mounting which allows the valve to
be automated without losing seal integrity, as the body does not require disassembly. Manual to remote
control may therefore be easily accomplished by fitting a BVA300 series pneumatic actuator available from
Spirax Sarco. For further details contact Spirax Sarco.
Available types and applications
Has an API 607 firesafe design, zinc plated carbon steel body and PDR 0.8 seats (for
M33F2 ISO
high temperatures)
Has an API 607 firesafe design, stainless steel body and PDR 0.8 seats (for high
M33F3 ISO
temperatures)
API 607 firesafe design - In normal working conditions, the ball rests against two PDR
0.8 seats ensuring total closure. When the valve is submitted to temperature above the
limits the seats can withstand, the seat becomes deformed and renders to extrusion. When
the seats have been totally destroyed, the ball will come to rest firmly against the metal
seat in the cap, producing a metal-to-metal closing. This secondary seat in the valve cap
ensures the valve will operate to international API 607 standards.
Applications
M33S2 ISO
Zinc plated carbon steel body and PDR 0.8 seats (for high temperatures)
M33S3 ISO
Stainless steel body and PDR 0.8 seats (for high temperatures)
Applications
M33V2 ISO
Zinc plated carbon steel body and PTFE seats
M33V3 ISO
Stainless steel body and PTFE seats
