check valve in pump discharge line

<...place check valve in pump discharge line...>

It is widely done, especially where there are multiple pumps. Select a valve that is suitable for the forward flow, line pressure and back-pressure. The wetted materials must obviously be suitable for the fluid. Talk to a valves distributor locally.

<...What care should be taken while placing Pressure relief valve on vessel/Pipe.

What are all the criteria for FLARE pipe rouing and tower piping...>

It sounds as though the first thing to do is to put the changes through a HazOp study.

You need to include a lot more info. The best and most durable check valve that can be installed in any position is made by "Drabla" they are stainless steel and are steam boiler feed water rated.

I think it's ok,maybe you can use the vertical type which the door inside like wing of the butterfly....

thank's

Vertical Swing type with swing opening on pressure and close when pump stops.

For relief valve -pressure setting and return line to tank are important.

Yes a valve can be place in a discharge line. If the the vertical run after the valve is of some great length in would not recommend the use of Y or swinging gate type check. The weight of the water will cause the valve to slam shut can be quite damaging to the valve and noisy. Use the spring type. Would also install valve above and a union below it if in a long run for repairs or replacement.

You can put this valve vertically towards the door.But you have to choose your valve which is best quality....For this you can contact to any company which provide ths with the help of google.
