Gate valves are reliable when used properly. However, like all valves, they are subject to wear and tear and can eventually fail. When a gate valve fails, it is usually because the seals have worn out or the mechanism has become jammed.
Yes, gate valves are still used. They are one of the most common types of valves used in the world. Gate valves are used in a wide variety of applications, including oil and gas, water, chemicals, and power.
A ball valve can be used in place of a gate valve, but there are a few things to keep in mind. Ball valves are designed to be used in on/off applications, so they are not ideal for regulating flow. They are also not as durable as gate valves and can be more difficult to repair.
Gate valves are designed to start or stop flow in a pipeline, and therefore have a unidirectional flow path. When fully open, the gate is completely removed from the flow path and does not cause any significant flow restriction.

Both the grey water valve and the black water valve were replaced. Because of the single piece split tank construction on my Lance camper, the clearances were extremely small. I was able to line the valves correctly after removing and replacing both of them for over an hour. The issue, which was most likely specific to my application, is that the seal gaskets on either side of the sliding blade are loose in their recesses on the valve and are simple to dislodge while maneuvering the replacement valve into place. I made a small improvement to my efforts by applying silicon grease to the seats to help hold them in position. Given that one would typically replace the entire valve anyhow, it would have been a far better idea to have them attached to their seats.

In my workshop, I actually employed this in a do-it-yourself dust collection system (much cheaper than 4" blast gates and tubes and just as good for a small shop).They've been operating flawlessly for a few months. Even after being heavily exposed to sawdust, the gates are quite simple to open and close. provides an airtight seal, and the pre-lubricated gates make them easier to use and last longer. The fittings were very secure, and the body around the gate is sufficiently robust to withstand bumps and vibrations without any problems.

I bought this to make a koi pond. Great results. I need this while cleaning my 3" to 2" cleanout or, for that matter, emptying out my pump basket because my pump is below the water line; otherwise, water will rush through and empty out my pond. It doesn't breach the bank and stops the water as anticipated.The valve doesn't feel like it will close on its own when it is up and remains up. To be safe, I'll cut some PVC to use as a safety lock mechanism on the handle or pole. This will prevent anyone from closing the valve (pushing it down) unless it was their intention.ABS glue was used to join 3" ABS, and there was no leaking. It was simple to install, even though I had never done any pipe work before this build. In case I made a mistake and had to clip it out and redo my connection, I left some space on both ends. I'm happy with this purchase.

We applied this to the pool where our PIGS swim (yes, pigs love water).On our organic farm, we rear pigs, and this works fantastically as a drain valve.While permitting easy solid flow, it holds 500 gallons of water.It is MUCH simpler to open the valve than it is to use a ball valve.I advise using this valve.

In the plumbing system of my backyard pond, I had numerous of these installed. To manage flow, keep in mind that gate valves are truly only intended to be fully open or fully closed. Use a ball valve to control the flow if necessary. However, the manufacturer produces other types of these with various valve materials, locking handles, and interchangeable diaphragm materials. This valve features glue-on fittings and locks that fit into a small groove in the handle. In this model, the diaphragm cannot be serviced. I choose this particular model since, in the case of a failure in the future, they weren't situated in a crucial area of the plumbing and could be quickly replaced by chopping out the PVC component.Choose one of the other models for installation and service if your application is different.

Despite the fact that this product seems to be a nice one, I prefer the waterway brand that I got for a new installation job. It's really challenging to open and close this one. Nevertheless a quality product, I now prefer the other brand after purchasing another.

Due to their significantly reduced price, they're a fantastic substitute for ball valves, especially in the bigger sizes. However, there are a few factors to keep in mind:1. They function, but because of the weight of the valve, they may gradually close on their own. They aren't really designed to slow the flow of water.2. If there is any debris in the water, it may collect into the valve seat or slot and prevent the valve from shutting all the way. If it's the main drain valve on, say, a sizable fishpond, this could range from being a little inconvenience to a serious concern.3. They are only meant to be used in low-pressure situations, such as pond drains, where the water pressure is only a few psi at most.4. Although mine have not dripped, I have read that they may do so even when fully closed.
A gate valve is designed to reduce pressure in a piping system. The valve is installed in a pipeline and allows for a controlled release of pressure. By releasing pressure gradually, the valve prevents sudden changes in pressure that could damage the pipeline or cause an accident.
A gate valve is a linear motion valve that is used to start or stop fluid flow. The gate is lifted out of the path of the fluid by turning the handle or wheel attached to the stem.
A gate valve is a particular type of valve used for controlling the flow of liquids and gases. The gate valve is opened by lifting a round or rectangular gate/wedge out of the path of the fluid. The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar, so gate valves are often used when a straight-line flow of fluid and minimum flow restriction is desired. Gate valves are classified as either rising stem and non-rising stem types. In a rising stem gate valve, as the wheel is turned to open or close the
There are several disadvantages of gate valves. First, they are not as durable as other types of valves and are more likely to break or leak over time. Second, they are not as easy to repair as other types of valves, so it may be necessary to replace the entire valve if it breaks or leaks. Finally, gate valves can be difficult to operate, so you may need to hire a professional to install or repair them.
Gate valves and butterfly valves are two types of valves that are used for different purposes. Gate valves are used to control the flow of liquids and gases, while butterfly valves are used to regulate the flow of liquids. Here are some advantages of gate valves over butterfly valves: 1. Gate valves are more durable and can withstand more wear and tear than butterfly valves. 2. Gate valves are less likely to leak than butterfly valves. 3. Gate valves can be used to control the flow of both liquids and gases, while butterfly valves are only suitable for controlling the flow of
