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

Why Chiba's Refining (ENEOS, Cosmo Oil Chiba) Sector Needs Compressed Gas & CNG Systems Valves

Chiba anchors Japan's Keiyo Industrial Zone along Tokyo Bay - one of the country's largest integrated hydrocarbon, chemical, and steel complexes - combining ENEOS and Cosmo Oil refineries, Sumitomo Chemical, Mitsui Chemicals, and Maruzen petrochemical plants, JFE Steel's East Japan Works, and the JERA Sodegaura LNG and power terminals; this breadth demands an unusually wide valve portfolio to JIS/JPI and licensor standards - API 6D and JIS B2071 ball, gate, and globe valves in A216 WCB and A351 CF8M for refinery and petrochemical lines, high-temperature WC9 and F22 valves for cracking and reforming, cryogenic gate and ball valves for the LNG terminals, high-temperature and abrasion-resistant valves for blast-furnace and steelmaking duty, fire-safe and low-fugitive valves for emissions control, and API 526 safety-relief valves; JIS B2220 flanges and full traceability are required; Vajra Industrial Solutions supplies Chiba refinery, petrochemical, steel, and LNG buyers with API 6D, high-temperature, cryogenic, and low-emission valve packages with JIS-compliant connections and full material certification. Key facilities in the Chiba area - including Keiyo Industrial Zone (Chiba-Ichihara-Sodegaura), ENEOS and Cosmo Oil Chiba refineries, JFE Steel East Japan Works - rely on CNG Ball Valve (Class 2500) for their steel (jfe steel east japan works) operations. Vajra Industrial Solutions supplies CNG Ball Valve (Class 2500), Gate Valve (City Gas Distribution), Safety Relief Valve (CNG), Ball Valve (Industrial Compressed Air/N₂) for compressed gas & cng systems projects across Chiba Prefecture, with full IS 15901 (CNG/CGD Valves) and PNGRB Regulations compliance documentation - EN 10204 3.1 material test certificates, API 598 pressure test reports, and third-party inspection co-ordination available for every order.

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.
