How can we do if the plastic ball valve too tight

PVC True Union ball valves are available in sizes ranging from ½” to 4”, providing a convenient and effective way to control system flow. The valve can be easily opened or closed by simply turning the plastic handle a quarter turn. These valves feature double union joints, making them easy to service and maintain, whether repairing or replacing them. The main part of the valve, called the bracket, houses the handle and ball and can be removed from the line for easy service without disassembling the entire system. True Union ball valves are available with socket or threaded ends and it is recommended to use PVC glue or thread tape when installing the valve in the pipe. These valves are extremely durable and tested to withstand pressures up to 150 PSI, making them suitable for use in industrial applications where quick response and ease of repair are critical.

What causes a PVC ball valve to leak?

PVC ball valves can leak for a number of reasons, including:

1, Improper installation:

If the valve is installed incorrectly, such as using the wrong type of sealant or not tightening the connections correctly, it can cause leaks.

2, Wear:

Over time, seals and O-rings in valves can degrade, causing leaks. This can be caused by exposure to harsh chemicals, high temperatures, or normal wear and tear from frequent use.

3, Damage:

Physical damage to the valve, such as cracks or breaks in the PVC material, may cause leakage.

4, High Pressure:

Excessive pressure in the system can cause valve leakage, especially when the pressure exceeds the valve’s recommended PSI.

5, Corrosion:

Exposure to corrosive substances or environments can degrade PVC materials, causing leaks over time.

To prevent leaks, it is important to ensure proper installation, use appropriate sealants, regularly inspect valves for wear and damage, and operate valves within specified pressure limits. Regular maintenance and timely replacement of worn parts can help prevent leaks and ensure the normal operation of PVC ball valves.

UPVC plastic ball valves are not only acid-resistant, alkali-resistant and corrosion-resistant, but also have high mechanical strength and meet the national drinking water health standards. Product sealing performance is excellent, is widely used in civil construction, chemical, pharmaceutical, petrochemical, metallurgy, agricultural irrigation, aquaculture and other water pipeline systems.

What are reasons of the plastic ball valve too tight?

Plastic ball valves after a period of time, due to internal impurities, dust and other reasons, it is very easy to cause the switch is not smooth, seriously affecting the use of the effect. At this time, if forced to open or close will make the internal parts of the valve is damaged, more often than not due to wear and tear or pollution of steel parts, thus appearing too tight.

How to deal with the plastic ball valve too tight?

1. With lubricant: first of all, check whether there is dust or other debris on the stem of the plastic ball valve, if there is, you can wipe it clean, and then drop a drop of lubricant on the stem, and then repeat the switch a few times, so that it is uniformly lubricated, and the valve will gradually come alive.

2. Hot water immersion: the plastic ball valve in hot water for a few minutes, so that the material is slightly expanded, the valve will be able to easily turn.

3. Disassembly and cleaning: If the first and second methods are unable to solve the problem, then it is recommended to disassemble and clean. The valve will be disassembled to remove the stem surface of the dirt or other foreign objects, and then installed, you can restore the smooth state of the switch.

How to avoid plastic ball valve too tight?

1. Regular cleaning: regular cleaning of plastic ball valves can effectively avoid the valve too tight, it is recommended that every six months or a year for cleaning and maintenance.

2. Attention during installation: When installing plastic ball valves must pay attention to the installation position and direction is correct, can not be installed in reverse or installation is not flat, otherwise it will lead to the valve does not flow.

In short, if there is a problem with the plastic ball valve, do not rush to force the switch, you can try to use the above methods to solve.
