Q:anti siphon valve?
as you stated, you said the directions said at least 6 from the highest sprinkler 7 will be ok as well as 20. i don't know what region you are in, but if you are in a freeze zone though it is always a good idea to blow the lines when winter comes around.
Q:butterfly valves d7a1x5
D- valve type (butterfly valve), 7- connection mode (to clamp), A- valve shape mode (A), 1- structure form (vertical plate), X5- valve seat sealant species (Ding Qing, NBR)
Q:How can you tell the difference between a functional valve murmur and a non-functioning valve murmur?

Q:What if the function of a valve retainer?
This Site Might Help You. RE: What if the function of a valve retainer? Specifically an engine valve retainer.
Q:What's the difference between a clip type turbine butterfly valve and a flanged turbine butterfly valve?
The clip type valve bolts are generally longer, in high temperature conditions, bolt expansion may lead to leakage, so the high temperature conditions are not suitable for large diameter.But for the end and downstream pipeline occasions need to remove the clip on butterfly valve is generally not, because when the downstream flange dismounting clamp down, the valve will fall down, it must do in order to remove the nipple, and the flange type butterfly valve does not exist on the surface of the problem, but the cost will be relatively high.
Q:How warm is the PTFE butterfly valve?
Ordinary PTFE clip butterfly valve normal temperature tolerance of about 120 degrees, instantly to about 150 degrees
Q:What does butterfly valve do?
Butterfly valve (English: butterfly valve) refers to the closure of parts (valve or butterfly plate) for the disk, around the valve shaft to achieve rotation and closure of a valve, the main cut off on the pipe and throttling. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation. Butterfly valve is fully open to fully closed is usually less than 90 degrees, butterfly and butterfly stroke itself has no self-locking capability, in order to position the disc to install the valve stem on the worm gear. Using worm gear reducer, not only can the butterfly plate have self-locking ability, so that the butterfly board stops at any position, but also can improve the operation performance of the valve. Industrial butterfly valve features, capable of high temperature, applicable pressure range is higher, the valve nominal diameter is large, the valve made of carbon steel, the valve plate sealing ring using metal rings instead of rubber rings. Large high temperature butterfly valve welded by steel plate, mainly used for high temperature smoke duct and gas pipe.
Q:What is the principle of butterfly valve and check valve? Any difference?
Crown valve pressButterfly valve is butterfly valveThe check valve is a check valveButterfly valve is mainly switching functionThe check valve mainly stops the pipe from flowing backwardsThe two can only be said to be valvesThe others are different
Q:1 valve bugle fingering chart? (more complicated than it sounds)?
Baritone Bugle
Q:how does variable valve work?
The variable is the valve timing. The spark plug fires a split second before the piston reaches the top of the stroke, to give the fuel a bit of time to burn. But, the faster the piston travels in the bore, that split second gets shorter shorter. So the engine computer changes when the spark plug fires when the valves close, to maximize the power from each ignition stroke.
