Industrial and Commercial/Boiler/Combustion Pressure Regulation Solutions
RTZ-40/0.8 (LCS400) Gas Pressure Regulator
◉ Application
This pressure regulator is suitable for various direct-fired equipment and adaptable to multiple scenarios including residential areas, commercial premises, and industrial sites. It can be used with a variety of non-corrosive gases such as natural gas, artificial coal gas, and liquefied petroleum gas (LPG).
◉ Features
- High pressure regulation precision
- Sensitive shut-off response
- Simple pressure setting operation
- Longer service life
◉ Technical Parameters

- Flow Rate: 200 Nm³/h (Note: "Nm³/h" = "normal cubic meters per hour", a standard unit for gas flow measurement under standard conditions of 0 °C and 1 standard atmospheric pressure)
- Operating Temperature: -29 °C ~ 66 °C
- Nominal Diameter (DN): DN 40×DN 40, DN 50×DN 50
- Connection Type: NPT thread (Note: "NPT" = "National Pipe Thread Taper", a North American standard tapered thread for sealed pipe connections)
Supplementary Notes on Key Terms
- Pressure Unit Relationships: 1 bar = 1000 mbar = 100 KPa ≈ 14.5 Psi; understanding this helps in intuitively comparing pressure values in different units.
- Direct-fired Equipment: Refers to devices that use gas as fuel and burn it directly to produce heat or energy (e.g., gas stoves, industrial gas-fired boilers, commercial gas water heaters).
- Domestic Version: Specifies parameters for the regulator model produced locally (in China), which may differ from international standard versions in pressure ranges to adapt to domestic gas system requirements.
