Critical Valve Requirements

PNGRB Type Approval - all valves used on City Gas Distribution networks in India require PNGRB approval; Vajra supplies PNGRB-approved CNG ball valves

IS 15901 compliance - Indian Standard for natural gas valves covering material, design, testing, and marking requirements specific to gas distribution

Fire-safe design per API 607 - mandatory for all CNG station valves in compressed gas service; metal seat backup prevents external fire leakage

Anti-static design - mandatory for natural gas service; conductive path between ball/stem and body to prevent electrostatic sparking

Fugitive emissions - ISO 15848-1 Class B or better for all valves on gas distribution mains; PNGRB requires zero-leak certification

Full-bore design for metering bypass and pigging - all trunk main isolation valves on CGD networks must be full-bore per PNGRB network code

What is PNGRB approval and which CNG valves require it?

The Petroleum and Natural Gas Regulatory Board (PNGRB) under the Indian Ministry of Petroleum regulates city gas distribution (CGD) networks. All equipment used on PNGRB-licensed CGD networks must be PNGRB type-approved, which involves testing to IS 15901 (for valves) and other Indian standards, followed by PNGRB listing. This applies to isolation valves on steel gas mains, service isolation valves, and CNG station valves. Valves at industrial consumers not connected to the CGD network (e.g., CNG used for industrial gas cylinders) may use standard API 6D or API 607 compliant valves without specific PNGRB approval.

What pressure class do I need for CNG station ball valves?

CNG is stored and dispensed at 200–250 bar (approximately 3,000–3,600 psi). ASME Class 2500 (PN 420) has a working pressure of approximately 414 bar at ambient temperature for WCB material - making it the standard pressure class for CNG station isolation valves. For cascade storage working at exactly 250 bar, Class 2500 provides adequate design margin. Use forged A182 F316 or F316L body (not cast WCB) for Class 2500 CNG service - forged bodies have better toughness and are the industry standard for high-pressure gas service.
