Schedule 40 PVC pipe is the standard thickness used for many drainage and water management applications. PVC pipe can handle temperatures up to 140˚F. The advantage of using PVC is the strength and rigidity versus the lightweight design. PVC is ideal for easy installation services. CPVC duct is useful for applications requiring non-corrosive material that can handle temperatures up to 200 degrees Fahrenheit. CPVC duct is also known for its fire resistant properties - making it ideal in high-risk laboratory or industrial situations. Compact ball valves are ball valves that are smaller than the average pvc ball valve. This means that they offer the ability to control flow and turn it on & off with the simple turn of a knob in small places that are hard to reach. These valves range in size between 0.2 inches to 2 inches. They can be either straight valves or incorporate a tee to help change the direction of flow.
