It can be confusing to pick between UPVC and PVC ball valves, especially if you’re not sure what makes them different. Both are used to control water flow, but they are not the same. The main differences are in how strong they are, how much heat they can handle, and how long they last. Let’s make it easy to understand.
UPVC means Unplasticized PVC. It is a hard and strong plastic. It doesn’t bend and is great for outdoor use. UPVC works well for water supply lines, plumbing, and irrigation. It can handle high pressure and sunlight. Choose UPVC if you want something that lasts longer and can handle tough conditions.
PVC means Polyvinyl Chloride. It is softer and lighter than UPVC. It is cheaper and good for small water jobs. PVC is best for gardens, small tanks, or low water pressure. It is not suitable for hot water or strong pressure. Choose PVC if you need a simple and low-cost valve.
