HEAT EXCHANGER PIPING
HEAT EXCHANGER PIPING
(OP)
Where can I get a reference for the piping connection of a PLATE HEAT EXCHAGER? Can somebody provide a good book for this subject.

Isoltion valves are a must for maintenenace. Provide at least an additional space for 20% more plates if needed in the future. Provide space to pull the plates so they can be cleaned.
Never used a double regulating valve on this system. Im assuming you have a glycol HW coil, and the system is not glycol, hence the reason for the HX.
Another thing to look into is the fouling factor. 3-way valves may help in keeping full flow to minimuze fouling.

The OP provided no details about the application: Is there steam on one side? How big is the piping? Is the question about welded-plate heat exchanger?
Better to ask a specific question, such as: is it necessary to use eccentric reducers if they are in the horizontal pipes to the inlet connections? There may be a variety of answers pro and con, but it would focus the discussion and demonstrate that the OP looked at a few on-line resources before asking an unanswerable question.
RE: HEAT EXCHANGER PIPING
Actually we have two systems having a separate H.E. that have the same questions, (1) is for HOT WATER SUPPLY FOR AHU'S and (2) for DOMESTIC HOT WATER SUPPLY FOR THE BLDG. Both system will received water having a temperature of 155 deg cel. from a main line to the hot side of H.E. Now the only valves that we install are gate valve & strainer on entering supply while on the leaving are gate valve & double regulating valve with flow switch.
I just need a reference so that I can defend the work that I have done.
RE: HEAT EXCHANGER PIPING
There should be a two-way or three-way valve on the primary side that regulates based on the secondary side temperature.

Why are the heat exchangers installed? If they are only to separate a 15 psi steam boiler from water systems operating at higher pressures, maybe no controls are needed at the heat exchanger.
