Manufacturer and marketer of valves, actuators and controls Tyco Flow Control, a business division of Tyco International, is expanding its Anderson Greenwood instrument valve line by introducing the new M30 Series primary isolation instrumentation root valve.

This large-bore isolation valve can be used in applications such as upgraders, refineries, chemical plants and power-generating facilities, as well as at unconventional petroleum projects, such as oil-sands production and high-pressure, natural gas shale-field production.

The M30 Series includes single block, block-and-bleed and double block-and-bleed functions, which are built into a compact, modular, single valve body. These functions eliminate the need for field assembly as the different valves are already bolted together.

The M30 Series provides a robust bonnet with external stem threads, a metal seat and a 76 mm or 203 mm large-bore orifice, which is the first to be provided with a 538 ºC temperature range in a modular valve.

The combination of a nonrotating stem ball, a globe pattern flow path, and unique seat and stem materials provides a zero-leakage, repeatable bubble-tight shutoff, with low-turning torque.

In addition, all valves are designed to the American National Standards Institute B16.34 piping class rating, and are tested to an instrument-class shutoff specification to ensure positive closure in the most difficult of applications.
