TWO-WAY CAST IRON PLUG VALVES
Optimized for China Manufacturing Network & Industrial Gas/Oil Applications
Product Overview
The X43W Two-Way Cast Iron Plug Valve is a robust, cost-effective solution for industrial gas and oil pipelines requiring reliable shutoff and flow control. Constructed from ductile iron (GGG40) with a bronze-plated plug, this valve combines corrosion resistance with mechanical durability. Its compact design and universal flange compatibility make it ideal for municipal gas networks, refineries, and fuel transfer systems.
