DN25 to DN50

Description

The M40Hi is a reduced bore ball valve, with a single piece body,

having ISO mounting as standard. As a main feature the valve has

a special ball which has received a surface hardening and also

benefits from having reinforced PEEK seats.

The M40Hi has been designed for use as an isolating valve, not a

control valve and can be installed in high temperature applications

such as steam up to 39 bar g and thermal oils.

Available types

M40Hi2 ISO Zinc plated carbon steel body, reinforced PEEK seats.

M40Hi3 ISO Stainless steel body, reinforced PEEK seats.
