Ductile iron Valve

Ductile Iron Valves Common Types

There are several main types of ductile iron valves from YINUO, as reputed China ductile iron valves factory, used in various industrial and municipal piping systems:

Ductile iron Butterfly Valve - Rotary action valve that uses a disc to regulate flow. For handling large flows with lower pressure drops.
Safety Air Ductile Iron Valves - are installed in pipelines to release or admit air as required during filling or draining of the line. They vent small pockets of air to prevent water hammer.
Ductile iron Gate Valve for water supply - Linear valve that raises/lowers a flat gate to start/stop flow. Primarily open/closed applications.
Ductile iron Fire Protection Check Valve - Allow fluid flow in one direction only to prevent backflow. Use swing, lift, or tilting disk designs.
Ductile iron Water Flow Indicator with Retard - A device used in fire sprinkler systems to provide a visual confirmation of water flow.
Ductile Cast Iron Y strainers - Screen baskets made of stainless steel or other corrosion resistant material are placed in the bottom openings to capture solids.

What Is Ductile Iron Valve?

A UL Ductile iron valve is predominantly crafted from ductile iron, a type of iron that contains spheroidized free carbon, commonly referred to as graphite. The notable abundance of graphite nodules within ductile iron results in superior mechanical properties compared to other forms of cast iron.

Ductile VS. Cast Iron Valves: What’s The Difference?

In contrast to cast iron, ductile iron exhibits flexibility and does not fracture when subjected to bending, making it highly suitable for demanding applications.
Ductile iron is known for its strength and reliability, making it an excellent choice for pipes, fittings and valves.
However, it is important to note that ductile iron is generally price higher than cast iron due to its more intricate chemical composition.

Red RAL300 Coating Ductile Iron Valves Features

YINUO – Wafer Type Butterfly Valve Suppliers always provides quality ductile iron valves with Red RAL300 finished, list the features below:

Made of ductile iron, which provides strength for high pressure ratings along with resilient performance to resist shocks and vibration.
Full port design ensures minimal head loss through the valve.
Flanged, mechanical joint or grooved end connections to suit various piping systems.
RAL3000 is a traffic red polyurethane coating applied to critical iron surfaces.
The coating is corrosion resistant, insulating and impact resistant to protect the valve from harsh environmental conditions.
For buried infrastructure applications, it allows easy visual identification of the valve location after backfilling.
UV resistant for long-lasting color retention without fading.
Ductile iron valves for fire protection applications.
