I. Engineering Excellence & Technical Specifications
1.1 Robust Pressure Management Capabilities
This industrial-grade primary regulator delivers uncompromising performance in demanding environments. Engineered with direct-acting spring-load technology, it achieves AC10 precision classification (ISO 10533 standard) - maintaining outlet pressure within ±2.5% deviation across extreme flow fluctuations. The system handles:
Maximum Inlet Pressure (P1): 1.72MPa (250 PSI)
Configurable Outlet Ranges (P2):
Tier 1: 0.03~0.14MPa (4.3~20.3 PSI)
Tier 2: 0.1~0.28MPa (14.5~40.6 PSI)
Tier 3: 0.28~0.56MPa (40.6~81.2 PSI)
Peak Flow Capacity: 500 Nm³/h (17,657 SCFH)
1.2 Certified Safety Architecture
Featuring SG15-rated shutoff mechanism (EN 88-1 certified), the regulator:
Activates emergency closure within 0.8 seconds during 150% overpressure events
Maintains seal integrity at 60°C ambient temperatures
Withstands 100,000+ pressure cycles without seal degradation
1.3 Extreme Environment Resilience
Operational parameters exceed industry standards:
Temperature Range: -20°C to +60°C
Materials Engineering:
Body: ASTM A536 Ductile Iron (Grade 65-45-12)
