There are two major ways to maintain the valve for maximum and effective utilization. After the valve must have been damaged or performing below standard, attach the valve or perform preventative maintenance to operate the valve smoothly. Due to a sudden failure, poorly maintained valves cannot last long. These barriers interrupt the valve, leading to slower business, increased downtime, increased conversion costs and maintenance costs. You will learn how to maintain or extend the valve life of the entire facilities and hope to save a lot of money.
Know your valve
In industrial plants, the possibility of having different valves is high, as shown below.
- Ball valve
- Check valves
- Gate valve
- Butterfly valve
- Pressure reducing valves
When you understand how each valve works, you can plan a valve maintenance plan for your installation. Please pay attention to the specifications of different types of valves. You must know the type of valve construction and understand the physical characteristics of the valve. For example, PVC fittings with metal fittings can be used, but copper and brass cannot be mixed with KP-LOK tubing valves and steel fittings.
Technical specifications are also very important. Do you know the valve pressure and the temperature tolerance of the system? Once the valve is pushed to the limit, it will not be faster than valves designed for higher pressures and temperatures than normal. This does not mean that it is necessary to replace the products with higher tolerances with each valve in the system, but please pay attention to the weak points of the system by determining which valve has the highest load.
Clean the valves and ensure proper operation
Another important way to increase the life of the valve is to keep it clean. The amount of washing varies from one facility to another, but even in the cleanest facility, it must be washed at least once a year. In dusty plants and facilities that handle corrosive substances, depending on the severity of the problem, the valve should be cleaned every six months or more. Clean the valve body with a cloth, wire brush and lubricant. Keeping the valve clean will prevent the valve stem and other moving parts from expanding for a long time and holding the valve.
Check the valve regularly
Regular inspections are at the center of preventative maintenance programs. Valves with extremely high temperatures or pressure should be checked weekly or monthly, but less strain valves should be inspected every 6 months or annually. Check the valve body for cracks or other defects and check the gland nut or other parts to make sure everything is tight. If possible, turn the valve and check to be they are not clutching from accumulation of rust and minerals.
Leak detection must be part of the inspection procedure. In the case of valves that treat water, acids and other liquids, leaks are generally relatively easy to detect. Even if there is invisible moisture, leaking leaflets for 1-2 weeks often show signs of mineral deposition or corrosion in the enclosure.
Also some of the valves that handle refrigerants, compacted air, and other gases can be identified with water and soap mixtures. Spray this mixture on the valve and note that air bubbles are forming. Another possibility is to use an electronic leak detector. These devices are more effective than soap and water for two reasons. These can reduce the risk of errors and find small leaks.
Repair and maintenance work on modern industrial valves
We recommend shutting down the system each year by removing the valve, cleaning the internal mechanism and replacing worn parts. Over time, scale deposits, corrosion, and rust can affect valve stems, springs, coils, nuts, and other metal parts. In addition, many plastic and rubber parts need to be repaired or replaced.
After years of hard use, internal plastics and rubber wear, rot, harden and become brittle. It is always recommended to replace these parts with the first character rather than after a complete error.
It is also necessary to check if the valve disk is evenly in contact with the seat surface. To make sure your valve is properly closed, use the immersion method. If there is a problem with the seat of the valve, you can package it or reseat it if necessary. If you want to confirm the long life of the valve in the equipment, knowledge and regular inspections are very important. Regular cleaning and maintenance procedures can extend the life of the valve and reduce maintenance costs.
