M33H ISO
Full Bore Ball Valve
DN50 to DN200 ASME 150 and ASME 300
Description
The M33H ISO is a full bore, two-piece body, ball valve with
floating ball and has ISO mounting in accordance with ISO 5211,
as standard.
The M33H ISO has been designed for use as an isolating valve,
not a control valve, and can be used in high temperature
applications, such as steam up to 39 bar g and thermal oils.
