Cast Steel Check Valve

Have you checked the cast steel check valve recently? They need to be carefully maintained to ensure that fluids flow safely and prevent spills. Damage or wear can cause many problems. What systems do you have to ensure "healthy" check valves? We have simple guidelines for maintaining them.


Why are check valves important?


What is the purpose of the check valve? If you need fluid to flow through a pipe in one direction, you can't do without them. Check valves are designed with a two-way system with openings that allow fluid to pass through. After the flow has passed, the valve closes to prevent backflow. Check valves can also close automatically if downstream pressure is excessive.


Common uses of check valves:


  • Water and waste pumping systems

  • Water pipe

  • Sewage treatment system

  • Heating system

  • Fire hose

  • Marine and naval industries

  • Oil and gas pipelines

  • Flush toilet device

There are many different types of check valves, including rotary check, lift check, piston check, and ball check.

 

Maintain check valves


Gost Check Valve doesn't require much maintenance. They can last for years. However, if debris or other foreign matter gets stuck between the ball and seat, they may leak and reduce the check valve function.


Step 1: Keep it clean


Take action to keep the area clean to prevent damage to the check valve. If the valve can be reached, only a towel is needed to wipe off the dust and dirt. If crumbs clump, use a wire brush.

Step 2: Stay alert

Another simple trick is to check the equipment regularly. This is a great way to spot potential problems before you end up needing expensive repairs.

Check valve inspection:

Leak check

Look for signs of corrosion, rust, or mineral accumulation

Replace valve if there are large amounts of leaking or worn/damaged parts

Open and close valves to ensure they are not stuck

Check the pressure and temperature of the fluid passing through

Make sure they do not close or exceed the valve's rated limit

Note: Ensure that high pressure and high-pressure valves are monitored more frequently.


Step 3: Clean up everything


You will need to remove and remove the valve to check for debris and scratches. Clean all parts with hydraulic oil or any liquid used in the piping system.

Check the housing for corrosion, damage, or rough surface. Polishing can help with rough surfaces.

Step 4: Keep the valve lubricated


This step is usually ignored, but lubrication frees you from having to replace or repair the valve. It also ensures optimal check valve operation, making them last longer.

Turn the valve to ensure that the lubricant enters the valve chamber.

Make sure you use the right lubricant for the system. Each system has specific requirements and valves can be damaged if not used correctly. For example, lubricants containing clay or other solid thickeners may harden and leave residues.

 


Step 5: Apply protective insulation


Extreme temperature variations can affect the check valve function. They may even cause expensive damage. If your pipes are outdoors, you may need to add and check insulation during maintenance.

Maintain a check valve immediately. To prevent headaches later.

Maintaining check valves is the easiest way to prevent damage and costly repairs. These tips will help ensure that your valves work efficiently and safely.
