Industrial and Commercial/Boiler/Combustion Pressure Regulation Solutions

RTZ-8/1.7(LR632) Gas Pressure Regulator

• A、feature

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.

•  B、feature

Direct-acting type, two-stage pressure regulation, with inlet pressure of 1.7 MPa at the first stage and outlet pressure range of 1.7 kPa to 10 kPa at the second stage for user operation.

• C、Technical specifications

• Inlet Pressure (P₁): ≤ 17.2 bar
• Outlet Pressure (P₂):
  • 1.5 - 2.0 KPa

• Operating Temperature: -20 °C ~ 60 °C
• Nominal Diameter (DN):
  • DN 8×DN 15, DN 8×DN 20
  • DN 15×DN 15 (Custom-made)
  • Structure Type: Straight-through type
  • Connection Type: Threaded connection

Additional Notes on Technical Details:

1. Pressure Unit Conversion Reference: 1 bar = 100 KPa ≈ 14.5 psi (pounds per square inch). The inlet pressure here (≤17.2 bar) is approximately 1.72 times the standard atmospheric pressure, which helps in assessing the component’s pressure-bearing capacity.
2. Nominal Diameter (DN) Specifics: DN is a dimensionless nominal size for pipes/valves, not representing actual inner/outer diameter. For example, DN 8 roughly corresponds to a 1/4-inch pipe, DN 15 to 1/2-inch, and DN 20 to 3/4-inch in imperial units—this is useful for matching with existing pipeline systems during installation.
3. "Custom-made" Indication: The DN 15×DN 20 specification is marked as "Custom-made", reminding that this size may not be a standard off-the-shelf product and may require separate confirmation with the manufacturer regarding lead time and technical parameters.
