Critical Valve Requirements

Hydrogen service valves must comply with NACE MR0103 (refinery sour service) — hardness limits on body, trim, and fasteners
Ammonia service — extended bonnets for cryogenic applications below −29°C; fire-safe design per API 607
Urea melt valves — SS316L trim with PTFE packing; no copper-based alloys (urea attacks copper)
IBR certification for all steam valves above 3.5 kg/cm² — Form III-C material cert and Form III-E hydraulic test
API 526 compliance for all pressure safety valves; back-pressure correction for superimposed back-pressure
Anti-static and fire-safe design for liquid NH₃ storage valves — API 607 7th edition minimum

We offer export documentation and delivery to Beijing in 7–14 business days with full documentation and third-party inspection.
What certifications are required for ammonia & fertiliser plants valves in Beijing?
For ammonia & fertiliser plants in Beijing, the applicable standards are: API 6D, API 526 (PSV), NACE MR0103, ASME B16.34, API 598, IBR (Steam Valves), IS 2825. All valves are supplied with full documentation including material test reports (EN 10204 3.1/3.2), pressure test certificates, and dimensional inspection reports. Third-party inspection (TPI) by EIL, Bureau Veritas, Lloyd's Register, or the client's nominated inspector can be arranged.
What is the delivery time for ammonia & fertiliser plants valves to Beijing?
Standard stock sizes: export documentation and delivery to Beijing in 7–14 business days. Custom sizes and special materials (Duplex, Hastelloy, P91): 4–8 weeks manufacturing lead time. Express dispatch available for urgent site requirements. Contact us at +91-9979774557 or sales@vajravyuh.com with your specification and required delivery date.
What valve material should I use for anhydrous ammonia service?
For liquid ammonia (−33°C to ambient), use A350 LF2 carbon steel body with PTFE seats and SS316 trim — no copper, brass, or zinc alloys. For synthesis loop gas (H₂/N₂ at 150–300 bar), use A217 WC9 (Cr-Mo alloy) gate valves verified against the API 941 Nelson curves for hydrogen attack. For urea melt (185°C, 150 bar), SS316L is mandatory — carbamate in the loop attacks carbon steel rapidly.
Do ammonia plant valves need NACE MR0103 certification?
NACE MR0103 (Materials Resistant to Sulfphide Stress Cracking in Corrosive Petroleum Refining Environments) applies when H₂S is present — common in ammonia plants using natural gas feedstock via desulphurisation. Key requirement: body and trim hardness ≤ HRC 22 (Rockwell C). If your feedstock is H₂S-free coal or electrolysis, NACE may not be mandatory, but most licensors (Haldor Topsoe, KBR, Casale) specify it as a precaution.
