M40F ISO

Ball Valve - Firesafe

DN25 to DN150 ANSI Class 150 and ANSI Class 300

Description

The M40F ISO is a reduced bore ball valve, with a single piece

body, having ISO mounting and firesafe design as standard.

It is an isolating valve, which can be used with the majority

of industrial fluids, not a control valve.

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.

Available types

M40F2 ISO Zinc plated carbon steel body and PDR 0.8 seats.

M40F3 ISO Stainless steel body and PDR 0.8 seats.
