The M10HTi ISO three-piece body ball valve has a lockable
handle and ISO mounting as standard and features a special
ball, which has received a surface hardening. This particular ball
valve has been specially designed for applications that cannot use
Teflon at high temperatures, for example the tobacco industry.
The M10HTi ISO has been designed for use as an isolating valve,
not a control valve, and can be serviced without removal from
the pipeline.
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 easily
accomplished by the ISO range of Spirax Sarco ball valves.
Flanged
