Gate valves, also known as sluice valves, are designed to provide effective isolation of water flow in residential and commercial plumbing systems, irrigation networks, and other general water applications. Gate valves operate by lifting a gate or wedge in the path of the fluid.
Gate valves operate by lifting a gate or wedge internally in the path of the fluid. When fully open, the gate is lifted completely out of the flow path, resulting in minimal flow restriction and low pressure loss. Full bore construction further helps maximise flow capacity.
There are two main types of gate valves available- general purpose gate valves and WaterMark approved gate valves. General purpose gate vavles are of much lower costs and suitable for applications that do not come in contact with portable water, such as irrigations. WaterMark approved gate valves feature thicker gauge valve body and DR brass material suitable for portable water applications where the water must meet drinking standards, but at higher costs.
Compared to ball valves, gate valves require multiple 360 degree turns VS 1/4 turn operations of ball valves. This means the ball valves are preferred in applications where frequent opening/shutting is needed, whereas gate valves are suitable in more industrial applications where the valves remain open or shut mostly.
