Poor performance in pressure control management usually starts with an incorrect installation design. In this diagram we illustrate what a correct modular installation should look like. The water control valve is properly protected by a strainer at the inlet and includes pressure gauge readings and gate valves to shut off the line for maintenance.

The ideal bypass system consists of adjustable direct acting control valves with their manual shut-off valves. Finally, to make the system safe we need air valves before and after the main line, as well as a relief valve to prevent unexpected pressure peaks. The direct acting control valves, and the pilots of the main control valve, can be of the relief or reducing type depending on the function.
