Slide gate valves primary function is to stay the water pressure in check. Thanks to constant water pressure the probabilities of wear and tear and tear of any a part of the valves increases. As such, it’s highly recommended that the valves must be thoroughly checked prior just for smooth and trouble free functioning. However, thanks to one reason or the opposite if the valve happens to urge damaged it should get replaced on urgent basis to attenuate the danger of occurrence of any major problem.
Following are some simple steps regarding how to build a sliding gate, if followed in sequential order will cause successful installation of the slide gate valve with minimum of fuss.
Turn Off The Water System
Make sure to show off the water system from the mains on both phases of meter. Place the bucket underneath the valve so on avoid spilling of water everywhere.
Loosen Out The Nut
Next, grab an adjustable spanner to securely hold the valve. It’s best to use an open-ended wrench to relax the compression nut such if there’s any water pressure, all the water drains out immediately.
Loosen Out The Bonnet
Take an adjustable spanner so as to get rid of the stem that enters into the valves housing. If it’s screwed during a proper fashion then you would like to form sure that housing is well in situ and is firmly held with the wrench. All you would like is to seek out an appropriate size of open wrench to show the bonnet.
Removal Of The Bonnet
Next, you would like to carefully remove the bonnet from the slide gate valve housing ensuring that the disk is unbroken with the bonnet during the removal procedure.
Replacing The Valve
If there are any damage seats or clean the seats, replace the valve employing a rag. The extent of injury incurred on the sides or any kind of wear and tear of the disk.
Replacing The Disk Slot If Required
Check out the disk slot for any damage or crack. If there’s any damage then immediately replace the slot by sliding the stem out from the disk slot.
Replacing The Stem If Required
If the stem doesn’t turn (function) in proper fashion or if it tends to stay then, it must get replaced. Some sorts of the stems are often unscrewed directly from the bonnet.
Reassembling The Gate Valve
The gate valve needs to be reassembled systematically by sliding both the bonnet, disk and stem into the housing. Make use of adjustable spanner to tighten the bonnet and therefore the compression nut. While tightening you would like to form sure you are doing not apply much pressure. If you appear to note this, then the valve isn’t sticking.
Checking The Valve For Leaks
Check the valve by turning on the availability of water to form sure that everything is so as, and there are not any leaks. If there’s any leaking turn of the water system, fix that part immediately and check once more, until you’re satisfied completely.
