Stainless steel check valve is a one-way valve for pipelines, which only allows liquid/gas to move forward and not backward.
This type of valve is made of stainless steel, which is both corrosion-resistant and durable. The structural composition is even simpler!
Stainless steel casing:
Acid and alkali resistant (304/316L material), suitable for use in food and chemical factories.
Active valve disc:
Like a small door, it flows away when the water rushes open, and automatically closes with a “bang” when it flows back.
seal ring:
Made of rubber or PTFE material, it fits tightly when closing the door without leaking a single drop.
Stainless steel check valves are not only popular in the chemical and petroleum (anti acid backflow corrosion equipment), food and pharmaceutical (anti milk/drug contamination reflux) industries, but also indispensable in household water pipes (anti water heater cold water reflux and explosion of inner tank)!
