Frequently Asked Questions

What is a Nickel Aluminium Bronze (NAB) ball valve?

A Nickel Aluminium Bronze ball valve is made from ASTM B148 C95800 alloy, which offers exceptional corrosion resistance in seawater and marine environments. NAB valves are ideal for offshore platforms, shipbuilding, desalination plants, and fire protection systems.

What does 2PC construction mean in ball valves?

2PC (Two Piece) construction means the valve body consists of two parts - a center piece and an end connector. This design allows for easy maintenance and seat replacement without removing the valve from the pipeline.

What is a blow-out proof stem?

A blow-out proof stem design prevents the stem from being ejected from the valve body under pressure. The stem is retained by a shoulder that engages with the body, ensuring safety even if the stem packing fails.

What is PN16 pressure rating?

PN16 is a European pressure rating equivalent to 16 bar (232 PSI) at ambient temperature. It indicates the maximum allowable working pressure for the valve.
