Critical Valve Requirements

BFG valves must accommodate sticky tar deposits - knife gate or through-conduit design; no wedge gate (tar packs the body cavity)
Large-bore butterfly valves for BFG (DN600–DN2400) - double-offset design for bubble-tight shutoff required at change of wind direction
IBR certification mandatory for all steam valves above 3.5 kg/cm² in Indian steel plants - Form III-C material and Form III-E hydrostatic test
Blast furnace water cooling valves - continuous service, no shutoff allowed; use dual parallel valves for maintenance
Coke oven gas (COG) - naphthalene deposition blocks small ports; use full-bore valves only; minimum DN50
IS 6157 compliance for BFG gate valves manufactured in India

What certifications are required for coke oven & steel plants valves in Singrauli?
For coke oven & steel plants in Singrauli, the applicable standards are: IS 6157 (BFG Gate Valves), ASME B16.34, IBR 1950 (Steam), API 600, API 609, IS 2825, ASME B16.10. All valves are supplied with full documentation including material test reports (EN 10204 3.1/3.2), pressure test certificates, and dimensional inspection reports.

Express dispatch available for urgent site requirements. Contact us at +91-9979774557 or sales@vajravyuh.com with your specification and required delivery date.
Why are knife gate valves preferred for blast furnace gas?
Conventional wedge gate valves trap BFG tar and dust in the body cavity, causing the gate to seize. Knife gate valves have no body cavity - the blade cuts through the medium with a shear action, shedding deposits on actuation. The flat-face gate also allows easy replacement in-situ when the knife edge wears, without removing the body from the pipeline. For large BFG mains (DN600–DN2400), double-offset butterfly valves are preferred over knife gates for better shutoff and lower actuator torque.
What IBR documentation is required for steel plant steam valves?
All steam valves above 3.5 kg/cm² must carry IBR Form III-C (Certified Material Test Report from the steel mill, showing heat number, chemical analysis, and mechanical test results) and IBR Form III-E (Hydraulic Test Certificate from the valve manufacturer, showing test pressure = 1.5 × rated working pressure held for ≥ 30 minutes). Vajra supplies both certificates as part of the standard documentation package for all IBR-certified valves.
