Oil & Gas Valve Requirements
Oil and gas operations demand valves that deliver leak-tight isolation in hydrocarbon service, resist corrosion from sour crude and H₂S, withstand high temperatures in refinery process units, and provide precise control in gas processing and letdown applications. Safety, reliability, and fire-safe performance are non-negotiable.
Valve Solutions by Application
| Application | Valve Requirement | KSB Product |

Key Capabilities
Sour Service (NACE)
H₂S and high-CO₂ environments require NACE MR0175 compliant materials and hardness-controlled trim.
✓ SICCA valves in NACE-compliant CS/SS/alloy with controlled hardness
High Temperature Service
FCC, coker, and crude heater applications at 400–593°C demand alloy steel bodies and Stellite seats.
✓ SICCA pressure seal in WC6/WC9/C5/C12 with Stellite hard-facing
Fugitive Emission Control
Environmental regulations demand zero leakage on toxic and volatile fluids.
✓ ECOLINE bellow seal valves (BSGT-S/BSGL-S) with 316 Ti bellows
Gas Noise Reduction
Gas letdown near populated areas requires noise control below 85 dB(A).
✓ MIL 77000 labyrinth Lo-dB trim + MIL 78000 anti-cavitation
