1st Stage Regulator Gas Pressure Regulating Valve
1. Industrial-Grade Performance for Critical Applications
This Primary Gas Pressure Regulator delivers 200 Nm³/h flow capacity with AC5-grade precision (exceeding ISO 10533 standards), engineered for demanding commercial and industrial environments. Its heavy-duty cast aluminum body withstands inlet pressures up to 0.86MPa (125 PSI) - ideal for natural gas distribution hubs, LPG bulk plants, and manufacturing facilities. The SG20-rated shutoff mechanism ensures failsafe closure during pressure surges, while multi-gas compatibility (natural gas, LPG, biogas) reduces inventory costs for operators.
2. Advanced Engineering & Compliance
The regulator’s patented 3-stage pressure reduction system (illustrated in technical diagram cross-sections) features:
DIN-compliant flow channels with 325mm optimized flow path
Corrosion-resistant nickel-plated valve seats (visible in cutaway view)
Precision-balanced diaphragm (ø98mm active surface) enabling ±0.35% outlet pressure stability across all ranges (15-70 mbar)
Arctic-grade sealing compounds validated at -29℃ for oil/gas operations
Calibrated to maintain setpoints within 2.5 mbar deviation despite flow fluctuations, its thermo-compensated mechanism adjusts automatically to ambient temperature shifts (tested -29℃ to 66℃). Fully traceable materials comply with ASME B31.8 pipeline standards.
3. Future-Proof Installation Flexibility
Configured for dual DN40/DN50 NPT female threaded ports (per outlet pressure selection tables), this unit enables seamless retrofitting in legacy systems without adaptors. The dual-scale pressure gauge (PSI/mbar) accommodates global workforce requirements, while tool-free pressure adjustment via reinforced brass stem (visible in component diagram) simplifies field maintenance. Certified for critical infrastructure including CNG refueling stations, biogas power plants, and semiconductor fabrication cleanrooms where gas purity tolerance requires ISO Class 3 compliance.
