Low pressure valve and pressure reducing valve are different in function and use. Low pressure valve mainly refers to the working pressure is equal to or less than 1.57MPa(16kgf/cm2) of the valve, the nominal pressure PN ≤ 1.6Mpa. Low pressure valve is generally used for family gas stove or water heater, because of its low output pressure, small flow, suitable for family daily use scene.

Pressure reducing valve,Also known as a low pressure valve, it is relative to a medium pressure valve. The standard name is a bottled liquefied petroleum gas regulator. The pressure reducing valve reduces the inlet pressure to a certain required outlet pressure by adjusting, and relies on the energy of the medium itself to automatically keep the outlet pressure stable. The function of the pressure reducing valve is to reduce the pressure to achieve the purpose of controlling the downstream pressure, which is widely used in life, fire fighting and other industrial fluid control systems.
In practical applications, high-pressure valves and low-pressure valves are collectively referred to as pressure reducing valves, but their main difference lies in the difference in output pressure and flow. The high-pressure valve has high output pressure and large flow, which is suitable for occasions such as gas stoves that require greater power; while the low-pressure valve has low output pressure and small flow, which is suitable for daily use scenarios such as household gas stoves or water heaters.
In summary, although the low pressure valve and pressure reducing valve are mentioned as the same type of valve in some information, their main difference lies in the working pressure, use and output pressure and flow. The low pressure valve is mainly for daily use in the family, while the pressure reducing valve is a broader concept, including low pressure valve and high pressure valve, which is mainly used to control the pressure in the pipeline to ensure the safe and stable operation of the fluid system.
