Description

The M15 ISO three-piece body ball valve has ISO mounting and

metal seats as standard. This makes it suitable for working with fluids

that contain solids in suspension. It can be used on flow control

applications that use steam and other industrial fluids for services

ranging from vacuum to the higher temperatures and pressures. The

M15 ISO has been designed for use as a control valve not an isolating

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 safely and

easily accomplished by the ISO range of Spirax Sarco ball valves.
