Metal-seated severe service ball valves for low pressure applications

Solid rendition of ISOLATOR 2.0 valve

ASME 150 / 300 / 600 Standard Class: Designed for absolute isolation in low pressures and temperatures

ISOLATOR 2.0 is a metal-seated, bi-directional floating ball valve for absolute isolation in specific mining, refining, chemical/petrochemical, power generation and pulp & paper applications. This ASME 150-600 Class valve withstands temperatures to 1,000° F, and its durable materials of construction and proven coatings reflect its lineage of a longer life cycle over time.

Available in sizes 1/2 to 12 inch and in materials of construction that will suit your application.
