Use ball valves in your aquarium if you want to have flow all on or all off only. A ball valve are needed where you have equipment plumbed straight into a return line. If you need to disconnect your equipment it helps to get a ball valve that one could shut off, disconnect, and take off the equipment for maintenance or replacing. An example may well be a plumbed media reactor being feed by money pump that will require its media changed. You can simply close the ball valve at stvvalves , disconnect the canister, refill the media, reconnect, and open the valve to obtain the reactor operational again instantly. If you have a return pump, a ball valve between sump and pump is nice to get to service the pump as required. Ball valves doubles in RO/DI systems and in many cases on the end within your hose when filling freshwater containers.

Another great position for ball valves is using a manifold inside your plumbing. An aquarium manifold is often in line on going back line which could branch in the market to other lines many different functions. You never know when you’ll need to own a separate line to get a piece of equipment or maybe another plumbed in tank just like a frag tank. For a manifold, you can utilize PVC T connections which has a ball valve connected off of the T. When you are pre-made the line simply plumb with your equipment or second tank and open the valve only when it's ready for operation. Having this plumbed capable to go makes it easy to add upgrades or modify your system as you desire. Keep in mind that in case you add lines you need a bigger return pump to go water through more distance and equipment.

One problem that plumbers deal with on the regular basis could be the replacement of old shutoff valves. When installing or replacing a shutoff valve, you're faced that has a choice: ball valve or gate valve?

Since water inherently wreaks chaos on every aspect within your plumbing system, getting the proper valve available will help “delay” problems as time goes on. I use the definition of “delay” as an alternative to “prevent”, due to the fact when it comes to plumbing, problems will ALWAYS arise, it’s just a matter of the number of years. The gate valve has been in existence longer, and is also slowly becoming obsolete. The kind of the ball valve causes it to be vastly finer quality than the gate valve, and is also proven to stay longer and cause less problems.

The weight of segments may also be enormous as well as higher sizes and ratings this tends to cause valve stems to bend. A last resort might be modification within the design of valve body altogether, and also to consider supporting the gate/segment with the additional arrangement because will require space between gate/segment and valve body. Such a modification incurs additional cost, schedule and risk implications when running projects, and will not be feasible in any way.

The API 600 2015 edition mentions that the variety of normal gate valves should ensure correct alignment of gate and stem for those orientations. For sizes DN 650 and above, at least, wedge guides and the entire body guides are hard-faced permitting the valve for taking any orientation. But then furthermore, it talks about manufacturers providing of their installation and operational manual any limitations because of stem and valve orientation. API 6D isn't going to specifically address this problem and dictates for installation and operational manual for valves. Designers should discuss the matter extensively when obtaining technical clarifications from manufacturers, as opposed to waiting for cellular phone and operational manual following the purchase order.
