![]() ![]() Use a gate valve when you need to finely adjust the flow through the line. The hole on a ball is much smaller than on a gate valve so small changes when turning the know have a greater impact on the flow going through the valve making fine-tuning harder. When the valve is closed, the hole in the ball is covered by the walls of the pipe restricting water from flowing through the pipe. When the valve is open the hole in the ball allows water to flow through the line. As the name suggests, a ball valve uses a ball with a hole within the valve to allow or restrict flow when the ball valve’s knob is manually turned. Ball valves used in reef aquariums are made of PVC. What is a Ball Valve?Ī ball valve is similar to a gate valve where its main function is to restrict or allow flow through a line. A fully opened gate valve will restrict very little flow through the line and a closed valve should not allow any water through. Manual turns on the dial slowly moves the gate up and down making fine adjustments to flow possible. As the dial is opened the gate lifts and allows water to flow through the space underneath the gate. Flow adjustment is usually accomplished by an internal gate that is manually adjusted up or down by turning the valves dial. Most gate valves used in aquariums are made of PVC and come in various connection types and sizes. What is a Gate Valve?Ī gate valve is a plumbing device that is run in line with a pipe and can be adjusted to increase or decrease water flow through the line. Read on to find out more about using gate valves and ball valves in your reef aquarium. Ball valves can be used in locations where you simply need to turn off the flow to an area or piece of equipment. The #1 place for a gate valve is on your drain line or lines on your tank. Ball valves should be used when completely restricting or allowing water flow through the valve. You will want to use a gate valve when needing to fine-tune that amount of flow going through the valve. Two plumbing products that will help you accomplish this are gate valves and ball valves. Sometimes you will need to manually restrict the flow of water through your reef aquarium’s lines.
