M10F

Ball Valve

DN1⁄4" to DN21⁄2"

Description

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

as an isolating valve, not a control valve. It is antistatic and firesafe

as standard and can be serviced without removal from the pipeline.

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, that has been machined with the same radius as the ball,

ensures the valve will operate to international API Spec 6FA standard,

and BS 6755 part 2 standards.
