Valves are among the most critical components in Qatar’s oil and gas infrastructure. From the wellhead at a North Field gas facility to the pipeline network across Ras Laffan and the process control systems at Mesaieed’s refineries — the right valve in the right position is what keeps these systems running safely.
This guide covers the main industrial valve types used in Qatar’s petroleum and industrial sector and their specific applications.
“A valve failure in an oil and gas facility is not just an equipment problem — it is a safety event. Specifying the right valve matters enormously.”
Ball Valves — The Most Common in Qatar
Ball valves use a rotating sphere with a central bore to control flow. A quarter-turn opens or closes the valve completely. They are the most widely used valve type across Qatar’s oil and gas and industrial facilities because of their simplicity, reliability, fast operation, and tight shutoff. Ball valves are used for on-off service — where the flow is either fully open or fully closed — across a wide range of pressures and temperatures in Qatar’s process facilities.
Gate Valves — The Standard for Isolation
Gate valves use a sliding gate to control flow. They are designed for full-open or full-closed service — not for throttling. Gate valves are widely used as isolation valves on large-diameter pipeline systems across Qatar’s LNG and petrochemical facilities where their low pressure drop in the fully open position is an advantage.

Material Selection for Qatar’s Conditions
Qatar’s oil and gas fluids can be highly corrosive — containing H2S, CO2, and chlorides — which makes material selection as important as valve type selection. Carbon steel valves (ASTM A216 WCB) are standard for non-corrosive applications. Stainless steel (316/316L) is required where corrosion is a concern. For sour service (H2S) applications, materials must comply with NACE MR0175/ISO 15156 — a requirement that is strictly enforced at Ras Laffan and Mesaieed facilities.
MATERIALCRITICAL
Always specify the fluid type, temperature, pressure, and whether H2S is present when ordering valves for Qatar oil and gas applications. A standard carbon steel ball valve will fail rapidly in sour service without the correct material specification.
