Gate Valve

A gate valve slides up and down in the pipe to open and close. A gate valve should be used either fully open or fully closed not suitable to control pressure, damage can be caused from liquid if the valve is partially closed, it creates a minimal pressure drop when is open. They are often used as the first valve in a plumbing, also for domestic water system.

Gate valves are ideal for isolation of general purpose flows, as well as for high-pressure and high-temperature applications with no frequent operation. For this reason, manual operation is typical and generally accomplished through a multi-turn handwheel assembly; mechanical, pneumatic and electric activators are also available
