Industrial and Commercial/Boiler/Combustion Pressure Regulation Solutions
RTZ-25/1.7(L627) Gas Pressure Regulator
◉ Application
This pressure regulator is used for medium-pressure regulation in gas-fired boilers and gas supply adjustment for industrial and commercial users. It is suitable for natural gas, artificial coal gas, liquefied petroleum gas (LPG), biogas, and other non-corrosive gases.
◉ Features
It is a direct-acting gas pressure regulator with the following advantages:
- Accurate pressure adjustment
- Simple pressure setting
- Fast response speed
- Stable pressure regulation
- Large flow capacity
◉ Technical Parameters
- Inlet Pressure (P₁): ≤ 17.2 bar
- Outlet Pressure (P₂):
- 0.3 - 1.4 bar (Model 496)
- 1.0 - 2.8 bar (Model 497)
- 2.5 - 5.6 bar (Model 498)
- 4.8 - 10.3 bar (Model 499)Note: The numbers in parentheses (496/497/498/499) are inferred as model designations corresponding to different outlet pressure ranges.
- Pressure Stabilization Precision (A): AC 10
- Shut-off Pressure (Pᵦ): Sc15
- Flow Rate: 200 - 500 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: -20 °C ~ 60 °C
- Nominal Diameter (DN):
- DN 25×DN 25, with NPT thread connection
- DN 50×DN 50, with NPT thread connectionNote: "NPT" = "National Pipe Thread Taper", a North American standard tapered thread designed for sealed pipe connections to prevent gas leakage.
Supplementary Notes on Key Terms
- Direct-acting Gas Pressure Regulator: A type of regulator that uses the pressure of the regulated gas itself to drive the valve core and adjust pressure, without relying on external power (e.g., electricity, compressed air). It features a simple structure, high reliability, and is widely used in medium-pressure gas supply systems.
- Medium-pressure Regulation: Refers to pressure regulation in the "medium-pressure" segment of gas pipelines. For reference, gas supply systems typically divide pressure into low (≤0.2 bar), medium (0.2 - 4 bar), and high (>4 bar) levels—this regulator’s outlet pressure range (0.3 - 10.3 bar) covers medium to high-pressure scenarios, matching its application in industrial/commercial boilers.
- Biogas Adaptability: Biogas (a mixture mainly composed of methane) is a common renewable energy source; the regulator’s compatibility with biogas expands its application in energy-saving and environmental protection projects (e.g., biogas-fired boilers in farms, industrial parks).
