The function of a sprinkler pressure valve in a fire protection system is to regulate and control the water pressure within the system to ensure that the sprinklers operate effectively in case of a fire.
Did you mean Jockey Pump which is a small pump connected to a fire sprinkler system and intended to maintain pressure in a fire protection piping system to an artificially high level so the operation of a single fire sprinkler will cause a drop in pressure that will be sensed by the fire pumps automatic controller, causing the fire pump to start. The Jockey Pump is essentially a portion of the fire pumps control system.
A sprinkler bell valve in a fire protection system controls the flow of water to sprinkler heads. It opens when the system detects a fire, allowing water to flow and extinguish the fire.

A "fire department connection" (FDC) is often required on a sprinkler or standpipe system in case the ordinary supply of water fails to provide enough pressure for any reason. That way, a fire engine's pump can be used to pressurize the system with water from other sources.
A water gong is typically arranged to alarm the instant water in the sprinkler system begins flowing, certainly within a few seconds, as the pressure drops on the sprinkler side, allowing water pressure to turn the clapper in the gong.
To avoid problems of freezing water and broken pipes, a "dry sprinkler" system can be installed. The sprinkler heads can be sealed shut with temperature-sensitive valves, as in most wet systems, but the pipes are put under air pressure instead of water pressure, until one of the heads is activated by a fire. Water rushes into the system and sprays out of the open sprinkler head(s) within seconds, if all goes according to plan.
High water pressure from the street or well, but there's an exception: City water pressure (from the street) may need to have the pressure reduced to the home. Some homes have pressure regulators for this purpose, some do not. The same goes for well systems that use a pressure pump (an often a pressure tank); the outlet pressure is set so that the pressure to the home doesn't go too high or too low. An exception for homes with fire sprinkler systems. There is a check valve from the main water supply that feeds the fire sprinkler system. As temperatures drop at night, the water in the fire sprinkler pipes contracts slightly and additional water from the main water line goes into the fire sprinkler system. During the day, the water in the fire sprinkler pipes heats up and expands slightly, but has no where to go because of the check valve. This action can cause a very high pressure in the fire sprinkler pipes if there isn't also a pressure relief valve in the system. Numerous older homes do not have a pressure relief valve for the fire sprinkler system and risk having a pipe or joint burst. The bottom line: if you suspect that you have high water pressure in the home, consult a local plumber or building contractor for the appropriate solution.

Fire sprinkler systems are effectively already zoned - you don't need to do anything special. When your fire sprinkler system detects a fire, it doesn't set off all the sprinkler heads at once. Instead, each fire sprinkler head goes off when the temperature underneath it reaches a specific temperature, meaning only the ones affected by the fire will go off.
