The purpose of an isolation valve is to provide adequate shutoff to isolate one unit or pipe section from another. Green liquor creates heavy scaling on the valve components which can either inhibit isolation or damage the valve seats leading to poor shutoff. Unreliable isolation valves pose a safety risk to workers downstream or can inhibit maintenance activities.
A Velan Ball valve with Solids-Proof seat offers a hard high-strength metal seat which is capable of scraping scale from the ball. Such a design provides reliable operation and long term shutoff capability, improving safety and ensuring the valve works when you need it to. The solids proof seat construction provides smooth and reliable valve operation in processes that have a high scaling solids content.
