RTZ-15/0.8(LR622) 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, small size, light weight, stable performance, and easy operation

• C、Technical specifications

• 1、Inlet Pressure (P₁): ≤ 8 bar
• 2、Outlet Pressure (P₂):
  • 1.5 - 2.0 KPa
  • 2.5 - 3.1 KPa
  • 3.1 - 5.0 KPa
  • 5.0 - 8.7 KPa
  • 8.0 - 15 KPa
• 3、Pressure Stabilization Precision Class: AC 5
• 4、Shut-off Pressure Class: SG 10
• 5、Flow Rate: 18 - 30 Nm³/h (Note: "Nm³/h" refers to "normal cubic meters per hour", a standard unit for measuring gas flow under standard temperature and pressure conditions)
• 6、Operating Temperature: -20 °C ~ 60 °C
• 7、Nominal Diameter:
  • Straight-through type: DN 15×DN 20, DN 15×DN 15, DN 20×DN 20
  • Connection type: NPT thread (Note: "NPT" stands for "National Pipe Thread Taper", a standard tapered thread used for pipe connections in North America and other regions)

Key Notes on Technical Terms:

1. bar/KPa: Common pressure units. 1 bar = 100 KPa, which is approximately equal to standard atmospheric pressure (1 atm ≈ 1.013 bar).
2. DN (Nominal Diameter): A nominal size representing the approximate inner diameter of pipes/valves, not the actual precise dimension (e.g., DN 15 roughly corresponds to a 1/2-inch pipe in imperial units).
3. AC/SG Class: Industry-specific precision grading standards for pressure regulators (exact criteria may vary by manufacturer, but typically relate to pressure stability deviation and shut-off tightness).
