Oil & Gas Safety Valves engineered by Darshan Valve & Controls are specifically built to withstand hazardous upstream, midstream, and downstream hydrocarbon environments. Manufactured in strict compliance with API 520, API 526, and NACE MR0175 standards for sour gas (H2S) resistance, these safety valves prevent catastrophic pipeline overpressure, gas blowout, and refinery vessel failures. Constructed from heavy-duty forged alloy steels and stainless steels with stellite hard-faced trim, our oil and gas relief valves ensure bubble-tight seal tightness, zero fugitive emissions, and immediate high-capacity pop relief. They provide critical safety protection across offshore rigs, LPG/LNG terminals, cross-country gas pipelines, and petroleum refining plants.
