| Gate valves, also called a sluice valve or a pocket valve, are basically a valve that lifts out of the path of a liquid flow by lifting an obstructed round or square gate out of the way. The unique characteristic of a gate valve includes the straight-line flow of the liquid and the solid sealing surfaces along the gate are usually planar. A valve for any liquid flow has a seat area at the top, a stem area and a looping surface at the bottom. A gate valve basically has a seat and a looping surface. Normally, a valve is designed with one valve seat and one stem area.
A ball valve refers to the full port, single lead-free valves. Lead-free valves allow only a small amount of current to flow. These types of valves can be used in any applications where high efficiency and low temperature operation are required such as the aerospace industry.
A slotted ball valve is basically a type of full port ball valve but the difference is its placement inside the flange. As its name implies, the ball moves in a Slotted position within the flange while being protected by a rubber seat. This prevents the ball from turning as it is passed through the flange. When the valve is closed, the flow is limited to the space inside the flange. However, when the valve is open, it continues to rotate until the seat is fully loosened off the flange.
Sluice valves have been improved over the years. This quality is what has made them ideal for precision applications. Gate valvescan also be called sluices or seat clamps. In addition to the design of the seat, they also differ in the valve body\'s shape. They can either be dome shaped or flat. Most importantly, however, they can be adjusted depending on the kind of pressure that the application requires.
Gate valve technology has continued to evolve so that today you can find a wide variety of these products on sale eBay. They have been used for many years and there are many different types. There are also variations of these types. Some popular varieties include: flush mount, ball mounts, 4 inch gate valves, double play, twin play, oil-free, oil-less, spring, needle and many more. Check out the descriptions carefully so that you can choose the right ones for your specific application.
