Advantages and disadvantages of cast iron gate valves
Pipe fittings are widely used in various industrial and manufacturing industries. It is impossible to do without high-quality and reliable shut-off valves in the pipeline system. So, a cast-iron gate valve is especially in demand, which perfectly copes with the tasks set. What advantages and disadvantages of cast iron gate valves can be noted, we will find out further.
Features of the choice of cast iron gate valves
The main task of shut–off valves is to block the flow of liquid or gaseous substances that are transported through the pipeline. A gate valve with a rubberized valve is particularly effective at this task. It is used in heating and sanitation systems, and is also used for transporting various media, both chemical and industrial. The design of the gate valve is designed to ensure maximum tightness. This is achieved due to the maximum degree of compaction.
How to choose the right cast iron gate valves? Answering this question, you should pay attention to the following important parameters::
- The diameter of the passage hole.
- The working environment in which the shut-off valves will be used.
- The pressure indicator inside the system.
- The temperature indicator.
Thanks to the selection of parameters, it is possible to choose the optimal size of cast iron gate valves.
Pros and cons of cast iron gate valves
As we described earlier, cast iron gate valves have a number of main advantages. They are able not only to block the flow of the working fluid, but also to regulate it. These are durable and reliable elements of the pipeline system with a long service life. They are characterized by high resistance to corrosion. This significantly prolongs their operational life. We have reviewed the main advantages of using cast iron valves with a rubberized wedge.
However, some nuances of use can be noted. Cast iron is actually quite a heavy material, so the process of turning the valves can be slightly slowed down. In addition, cast iron is brittle, so it must be treated with caution. During operation, cast iron gate valves must be regularly checked for operability and changed as needed.
Shut-off valves of this type provide both horizontal and vertical installation options. They can be installed in pipelines that tolerate various aggressive media.
