M40HTi ISO (Tobacco)

Reduced Bore Ball Valves

DN25 to DN150 Flanged ASME 150 and ASME 300

Description

The M40HTi 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 Virgin PEEK seats.

The M40HTi can be used on applications that use steam and other

industrial fluids for services ranging from vacuum to the higher

temperatures and pressures. The M40HTi has been designed for

use as an isolating valve, not a control valve.

Available types

M40HTi2 ISO Zinc plated carbon steel body, Virgin PEEK seats.

M40HTi3 ISO Stainless steel body, Virgin PEEK seats.
