In natural gas distribution, industrial process lines, and commercial gas supply networks, gas regulating valves (also known as gas pressure regulators or gas pressure reducing valves) are essential for maintaining stable downstream pressure, ensuring safety, and optimizing system efficiency. These high-performance valves feature robust aluminum alloy construction, inlet pressure compensation, and automatic zero-flow shutdown, delivering reliable outlet pressure control regardless of upstream fluctuations or varying flow rates.
Designed for demanding applications, these regulators support maximum inlet pressures of 0.5 bar, 1 bar, or 4 bar and are available in DN50 to DN100 sizes with PN16 flanged connections.
الميزات الرئيسية والمزايا التقنية
These gas regulating valves incorporate advanced engineering for superior performance and safety:
- High Inlet Pressure Capability — Maximum inlet pressure ratings of 0.5 bar, 1 bar, or 4 bar with a lightweight yet durable aluminum alloy shell.
- Zero-Flow Automatic Shut-Off — Automatically closes when downstream demand drops to zero, preventing unnecessary gas consumption and enhancing safety.
- Inlet Pressure Compensation — Maintains constant outlet pressure based on the preset spring force, independent of inlet pressure variations or changes in gas flow rate.
- Flanged Connection Design — DN50–DN100 models use PN16 flanges for secure, leak-free installation in industrial piping systems.
- Wide Outlet Pressure Range — Adjustable from 70–350 mbar via color-coded springs for precise pressure selection.
- Broad Gas Compatibility — Suitable for air, city gas, natural gas, and liquefied petroleum gas (LPG).
- Wide Operating Temperature — Reliable performance from -10°C to +60°C.
- External Feedback Tube (for 1 bar & 4 bar models) — Rp3/8″ connection ensures accurate pressure sensing and stable regulation under high inlet pressure conditions.
These features make the valves far more responsive and stable than conventional regulators, minimizing pressure swings and improving overall system safety and efficiency.
Spring Selection Table
The outlet pressure is easily adjusted by selecting the appropriate color-coded spring:
| Outlet Pressure (mbar) | Spring Identification |
|---|
| 70–90 | Black |
| 100–160 | Red |
| 150–230 | Yellow |
| 220–350 | Green |
Note: Standard factory setting is 70–90 mbar (Black spring). Other ranges are available upon request.
التطبيقات الأساسية
