Why PVC Union Ball Valves Are a Great Choice

The union ball valve is a type of valve with two components – the first component is the actuator, which controls the flow of liquid through it. The second component is the valve itself, which contains the seat that controls the flow of liquid. PVC union ball valves are made of Polyvinyl Chloride (PVC). Hence, their name can be used in many different types of applications because they are so easy to install and use. Here are some of their other benefits.

Let’s Hope the guide from  Petron Thermoplast will help you. 

Main Benefits of PVC Union Ball Valve

PVC union ball valves are an excellent choice for water systems. They have a variety of benefits that make them well-suited for the job, such as: 

– Reduced maintenance 

– No metal parts to rust and cause problems 

– Easy to install – Less expensive than brass valves 

– Good for cold water use only

Things to Consider When Selecting a Valve Material

When selecting the material for your valve, there are many things to consider. The valve material you choose should be durable and withstand the environment in which it will be used. Some materials will not rust or react with certain fluids, while others may require less maintenance. There are also different valves, such as union ball valves. These valves offer a long-lasting seal and can withstand higher pressures than other valves. It is necessary to weigh your needs against the benefits of each type of valve before making your final decision. 


Whether indoors or outdoors, your chosen material should match the conditions. Materials like stainless steel, brass and bronze will not rust or react with various liquids. Another consideration is how much maintenance the material requires; some need to be cleaned periodically, while others are self-cleaning. A third consideration is whether the valves come standard with packing glands (i.e., small rubber pieces), O-rings (i.e., seals) or both, as these items wear out over time, requiring replacements.

Types of Ball Valves and How to Choose the Right Type for the Application

The type of ball valve you need for your Application depends on the flow direction, media, and temperature (among other factors). Each ball valves listed below have different flow directions and media compatibility. For example, needle-type ball valves are only compatible with gases or liquids that do not contain particles or fibres. In contrast, globe ball valves are best suited for Application with solids. Ball Valve Type Flow Direction Media Temperature Usage Needle Point in a specific direction Gases or liquids without particles or fibres Medium and high temperatures; chemical resistance Globe Rotates 360 degrees Solids High pressures; moderate temperatures; high viscosity Union Rotates 360 degrees Any liquid High-pressure operation.

Union ball valves can be rotated in any direction, making them very versatile.

5 Signs That You Need to Replace Your Valve

1) Lack of water pressure. A union ball valve is designed to be installed in the most restrictive area of your home’s plumbing system. If you notice reduced water pressure from your shower, faucet, or toilet, it may be time to inspect and replace your union ball valve. 2) Leaking or dripping pipes. If you notice small drips from your pipes and no discernible cause for the leak, then there is a good chance that this is due to an issue with your union ball valve. 3) The smell of rotten eggs. A strong sulfur smell usually indicates something has gone wrong inside the plumbing system, such as corrosion caused by chloramine gas or other chemical reactions from minerals in the water supply. 4) Buildup around the seal. Over time, the buildup can accumulate around the seal, reducing its efficiency and preventing adequate flow through the valve. 5) Constant low water pressure. Most PVC union ball valves are constructed with three seats: two on either side of a T-joint and one at the end of the pipe opposite where it connects to your plumbing fixture (i.e., sink, shower). When you have constant low water pressure coming from any outlet on your property – especially one near where your union ball valve is located – it may indicate that your seal needs to be replaced because they are wearing down over time.


Union ball valves are a great choice because they combine the benefits of both union and ball valves into one. They’re maintenance-free, a major concern for businesses that use valves daily. Union Ball Valves are also made of durable PVC material, which lasts longer than other materials. These features make Union Ball Valves an ideal choice for any business looking to purchase new valves.
