C-Series

Customizable isolation valves for specific applications

ASME 150 – 4500 Class: Dependable Isolation

The C-Series valve is the best choice in large bore isolation applications. MOGAS engineers have successfully designed the C-Series valve line which isolates under the extreme conditions – high temperature up to 1652°F (900°C), high pressures up to 43,000 psig (2965 bar g), media build-up, cycling with solids in the line and erosive attack of materials and coatings. With more than 40 years of engineering expertise, each C-Series valve is designed specifically for the application.

Each ball and seat subassembly is mate-lapped by hand and put through a rigorous testing procedure to ensure its integrity. The C-Series valve is available in full or reduced bore, ½ inch to 42 inches and in a wide variety of end connections.
