What is the use and features of the Expanding gate valves?
Expanding gate valves are used in various industrial areas like isolation valves in power plants, ESD valves in production, block valves in process systems, high temperature valves in refineries, and pipeline valves in critical areas. These expanding gate valves manufactured by various manufacturers are available in all the sizes, pressure ranges, and trims used in piping systems requiring the positive shut off of liquid or gas. The expanding gate valves are full bore through conduit valves with rising stem and parallel expanding gate and segment for tight mechanical seal and positive shutoff, both upstream and downstream, and under both low and high differential pressure. An expanding gate valves should have the following features: Parallel expanding gate design creates positive mechanical seal across both seats, both upstream and downstream, with or without line pressure. Non-rising stem permits valve installation in pressure drop.
Which direction is 'on' for the water main valve?
Ball valves: The handle will be parallel to the pipe when on and perpendicular when off. Gate valve: Clockwise off, Counter-Clockwise on.

What are Disadvantage of diode valve?
the disadvantages are that over a period of time gate valves seize and become in operable. also the handles of gate valves corrode quickly and gate valves don't entirely close properly making it difficult to solder. Gate valves are used for positive shut off and Gate valves are not designed for throttling like a globe pattern type .
