Description

Produced in accordance with API 6D the M33F ISO full bore

two-piece body ball valve with floating ball, has an API 607 firesafe

proof design. It is designed for use as an isolating valve, not a

control valve and can be used with the majority of industrial fluids

on applications, which include steam, condensate, water, oil,

gases, and other fluids within its operating range.

The M33F ISO ANSI has as standard an ISO mounting pad in

accordance with ISO 5211.

Firesafe design

In normal working conditions, the ball rests against two PDR 0.8

seats ensuring total closure. When the valve is submitted to

temperature above the limits the seats can withstand, the seat

becomes deformed and renders to extrusion. When the seats have

been totally destroyed, the ball will come to rest firmly against the

metal seat in the cap, producing a metal-to-metal closing. This

secondary seat in the valve cap ensures the valve will operate to

international API 607 standards.
