About:
An Alloy 20 Check Valve Manufacturer in Canada is a check valve made from an alloy of chromium, nickel, and molybdenum. It’s designed to be used in applications that involve sulfuric acid and other aggressive media.

Working:
It works by allowing fluid to flow in one direction while preventing backflow. They typically have a valve body, a seat, and a disc or ball that closes the valve opening when fluid flow reverses. The minimum pressure differential between the inlet and outlet required for the valve to open. The cracking pressure depends on the valve’s design and size. These valves can function as both stop valves and check valves. They are often used in drain lines and on the discharge side of pumps. The cracking pressure can be adjusted in the field by removing the valve from the piping system and compressing the spring. It is an austenitic stainless-steel grade that is often used to make valves. It is corrosion resistant to acids, including up to 40% concentrated boiling sulfuric acid.

Advantages:
The resistant to pitting, chloride ion corrosion, and crevice corrosion in chemicals that contain sulfuric, phosphoric, and nitric acids. The copper in the alloy protects it from sulfuric acid.
