Industrial and Commercial/Boiler/Combustion Pressure Regulation Solutions
RTZ-25/0.8(LHSR) Gas Pressure Regulator
This regulator is mainly used for pressure regulation in urban gas supply before entering households, small industrial and commercial users, gas boilers, etc. Suitable for natural gas, artificial coal gas, liquefied petroleum gas, biogas, and other non corrosive gases.
Direct acting, small size, light weight, stable performance, and easy operation

- C、Technical specifications
- Inlet Pressure (P₁): ≤ 8 bar
- Outlet Pressure (P₂):
- 1.5 - 2.0 KPa
- 2.5 - 3.1 KPa
- 3.1 - 5.0 KPa

- Flow Rate: 30 - 50 Nm³/h (Note: "Nm³/h" = "normal cubic meters per hour", a standard unit for gas flow measurement under standard temperature and pressure conditions)
- Operating Temperature: -20 °C ~ 60 °C
- Nominal Diameter (DN):
- DN 20×DN 20, DN 25×DN 25, DN 20×DN 25
- Connection Type: NPT thread (Note: "NPT" = "National Pipe Thread Taper", a North American standard tapered thread for pipe connections)
- Structure Type: Straight-through type, Angle type

Supplementary Explanations for Technical Terms:
- Pressure Units (bar/KPa): 1 bar = 100 KPa, approximately equivalent to 1 standard atmospheric pressure (1 atm ≈ 1.013 bar), which helps in intuitively understanding the pressure range.
- Nominal Diameter (DN): A nominal size used to standardize pipe/valve specifications, not the actual inner or outer diameter. For example, DN 20 roughly corresponds to a 3/4-inch pipe in imperial units, and DN 25 corresponds to a 1-inch pipe.
- Structure Types ("Straight-through type" & "Angle type"): Describe the flow path design of the component:
- "Straight-through type" means the fluid flows in a straight line through the component;
- "Angle type" means the fluid flow direction changes (usually 90°) when passing through the component, suitable for space-constrained installation scenarios.
