What is the Purpose of Cast Iron Valves?

While you may not hear them spoken about every day, cast iron valves work tirelessly behind the scenes of homes, businesses, and infrastructures.

Some of the many ways that cast iron valves get used every day include the following:

  • Home Use: Cast iron valves are used to help ensure flawless water flow throughout homes.
  • Gas Lines: In both home and industrial applications, cast iron valves are used to ensure smooth gas flow through controlled gas lines. This is essential for heating, cooking, and several other applications.
  • Reliable Energy Production: In the case of power stations and similar situations, cast iron valves are used to help regulate the control of various liquids that are vital to the energy production process.
  • City Infrastructure: From controlling and distributing potable water, to directing fluids in wastewater treatment plants, cast iron valves play a vital part in many different aspects of city infrastructure.

These are just a few of the places that regularly buy and use cast iron valves. They find uses in almost every type of application thanks to their strength, durability, and reliability. If you’re looking for a workhorse, purchase your cast iron valve today!

Cast Iron Valve Maintenance

While cast iron valves are renowned for their durability and resilience, basic maintenance can help preserve them. Their low maintenance requirements are definitely a major selling point for cast iron valves, but here are some things you can do to keep them in shape:

  • Perform regular visual inspections to check for cracks and leaks.
  • Periodically cycle the valve through its full range of motion to maintain smooth operation and prevent seizing.
  • Clean the exterior of the valve regularly.
  • Lubricate when necessary.
  • Clean the interior of the valve if debris build-up occurs.


When to Use and Not to Use Cast Iron Valves

Cast iron valves are very durable, but have drawbacks, and therefore their applications should be chosen carefully. They are seriously susceptible to oxidation when exposed to high humidity for long periods of time. Their low ductile strength means they should not be subjected to any kind of bending (such as in marine applications, as large ships tend to bend and flex with the motion of the sea: Navy regulations call for ductile iron). Cast iron valves should be avoided for applications involving excessively high pressures, as they are somewhat brittle. Cast iron is also susceptible to graphite corrosion (graphitization: surface and structure look fine, but the integrity of the metal weakens). This is caused by anything highly acidic. These conditions should be avoided where the application of cast iron valves are concerned. However, cast iron valves and cast iron piping are commonly used for water distribution, steam, plumbing, drain, waste, and vent plumbing applications. They are also used in many industrial and commercial applications. Cast iron valves are available in a wide range of sizes and configurations, including but not limited to, ball valves, gate valves, butterfly valves, and multi-piece valves like flanged valves.  You can shop cast iron valves through top manufacturers such as Milwaukee Valves through the ValveMan valve store.
