M10Si ISO

Ball Valve

DN1⁄4" to DN21⁄2"

Description

The M10Si ISO three-piece body ball valve has been designed

for use as an isolating valve, not a control valve, has a lockable

handle as standard and can be serviced without removal from the

pipeline (screwed and welded versions only). It can be used for

steam and other industrial fluids for services ranging from vacuum

to the higher temperatures and pressures.

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.
