The M10Si ISO Automation three-piece body ball valve has ISO
mounting as standard. It is designed for use as an automated
isolating valve, not a control valve, on applications that use steam
and other industrial fluids for services ranging from vacuum to the
higher temperatures and pressures.
The M10Si ISO Automation ball valve is specifically designed
for pneumatic or electric actuation and not manual operation
and can be serviced without removing the valve from the pipeline
(screwed and welded versions only).
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.
