ZRIO-A1 DI Body Flanged Gate Valves

It is a gate valve that means the gate valve components (including the valve body, the valve cover, the valve plate, and the handwheel, etc.) for the material of the ball. Compared with the cast steel valve, the ductile iron valve is higher than the right yield strength, and its corrosion resistance and antioxidant resistance exceed the cast steel, which is also much lower than the cast steel.

ZRIO-A1 DI Body Flanged Gate Valves FAQs

Q What is the Difference Between a Gate Valve and a Globe Valve?

The main difference between a gate valve and a globe valve is their inner elements and flow characteristics. The globe valve offers the good regulating ability, whereas the gate valve is best operated in a fully open or closed position. The globe valve is a regulation valve, whereas the gate valve is an isolation valve.

Another key difference between them is the direction in which they can be installed. A globe valve can be installed in a single direction, whereas a gate valve can be installed in various directions.

Q What is the Surface Treatment for Flanged Gate Valves?

Flanged Gate Valves can be either epoxy painting or epoxy coating.
