Description

The M10F ISO three-piece body ball valve has been designed for

use as an isolating valve, not a control valve, and can be serviced

without removal from the pipeline. It is antistatic, firesafe and has

ISO mounting as standard. The M10F can be used on applications

that use steam and other industrial fluids for services ranging from

vacuum to the higher temperatures and pressures.

Firesafe design

In normal working conditions, the ball rests against R-PTFE seals

ensuring total closure. Note: R-PTFE is PTFE reinforced with carbon

and graphite.

When the valve is submitted to temperature above the limits

R-PTFE can withstand, the seat becomes deformed and renders

the R-PTFE to extrusion. When the R-PTFE has been totally

destroyed, the ball will come to rest firmly against the metal seat

in the cap, producing a metal-metal closing. This secondary seat

in the valve cap ensures the valve will operate to international

API Spec 6 FA and BS 6755 part 2 standards.

ISO mounting

The integral ISO body mounting allows the valve to be automated

without losing seal integrity, as the body does not require

disassembly. Manual to remote control may therefore be safely and

easily accomplished by the ISO range of Spirax Sarco ball valves.

This product fully complies with the requirements of the

European Pressure Equipment Directive 97/23/EC and carries
