RTZ-15/1.7(LR622H) Gas Pressure Regulator

Industrial and Commercial/Boiler/Combustion Pressure Regulation Solutions

RTZ-25/0.8(LHSR) Gas Pressure Regulator

◉ Application

This pressure regulator is specifically designed for two-stage pressure reduction liquefied petroleum gas (LPG) systems. Its function is to reduce the pressure of the storage tank to 10 psig (0.69 bar).

◉ Features

• Long service life
• More precise pressure regulation performance
• Excellent overpressure safety protection performance
• Convenient system detection function
• Good corrosion resistance
• Excellent water drainage performance

◉ Technical Parameters

• Inlet Pressure (P₁): ≤ 17.2 bar
• Outlet Pressure (P₂):
  • 4 - 6 Psi (0.28 - 0.41 bar)
  • 8 - 12 Psi (0.55 - 0.83 bar)
• Pressure Stabilization Precision Class: AC 10
• Shut-off Pressure Class: SG 10
• Flow Rate: 18 - 30 Nm³/h (Note: "Nm³/h" = "normal cubic meters per hour", a standard unit for measuring gas flow under standard conditions of 0 °C and 1 standard atmospheric pressure)
• Operating Temperature: -20 °C ~ 60 °C
• Nominal Diameter (DN): DN 15×DN 15, DN 20×DN 20
  • Connection Type: NPT thread (Note: "NPT" = "National Pipe Thread Taper", a tapered pipe thread standard widely used in North America for sealed pipe connections)

Supplementary Notes on Key Terms

1. psig: Stands for "pounds per square inch gauge", a pressure unit that measures pressure relative to atmospheric pressure. 1 psig ≈ 0.06895 bar.
2. LPG (Liquefied Petroleum Gas): A flammable hydrocarbon gas mixture (mainly propane and butane) stored in a liquid state under pressure, which is the specific medium this regulator is designed for.
3. Two-stage pressure reduction: A pressure regulation process that reduces high-pressure gas to the required low pressure in two consecutive stages, ensuring more stable outlet pressure compared to single-stage reduction—critical for safe LPG use.
