While not as corrosive as strong acids or as viscous as some crude oils, water can still pose a risk to important machinery when it is left to collect in the wrong areas. Since the air in and around a system can often include some level of moisture, many mechanical systems will employ a drain valve to make sure collected water has a method to escape. Also used to help remove other unwanted fluids, gasses, or contaminants, drain valves are helpful components in industrial machinery which help protect them against blockage or corrosion. In this blog post, we will discuss the benefits of drain valves, exploring their working principles, different types, and their applications to help explain why they are so prevalent in industrial systems.
