Description

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.
