A safety valve is a valve that acts as a fail-safe.An example of safety valve is a pressure relief valve (PRV), which automatically releases a substance from a boiler, pressure vessel, or other system, when the pressure or temperature exceeds preset limits. Pilot-operated relief valves are a specialized type of pressure safety valve. A leak tight, lower cost, single emergency use option would ...
The most commonly used device for regulating gas flow in pipelines is the pressure reducing valve.These valves provide a mechanical constriction in the pipe, much as an orifice plate reduces the cross-sectional flow area, thereby effecting a local pressure drop in the flow. Commercial reducer valves are much more sophisticated than orifice plates, but they work on basically the same principle.

Pressure reducing valves or pressure regulating valves allow for a step down of pressure from a supply line to a process. These can come in different media types from water to steam, and even fuel oil. Temperature control valves are typically valves that operate off of a temperature sensor bulb
The Weil McLain boiler has an auto-fill valve that is designed to prevent the boiler from accumulating too much water pressure. However, you must set this valve to the proper limit or else it will not shut off the water supply early enough. Learn how to manually reduce the pressure before you work on the auto-fill valve.
