Oil & Gas Safety Valves
Oil and gas production, refining, and distribution demand specialized pressure relief valves meeting API 527, API 6D, and NACE corrosion standards. Aquatrol manufactures pilot-operated relief valves rated for hydrogen sulfide service, high-capacity offshore applications, and extreme pressure conditions up to 6,000 PSIG. Every valve is pressure-tested and certified for hydrocarbon service.
Why Aquatrol Oil & Gas Valves
Oil and gas systems operate at extreme pressures and encounter corrosive media (H2S, CO2) that demand specialized valve materials and designs. Aquatrol offers pilot-operated relief valves certified to API 527 (production equipment) and API 6D (pipeline) standards. Our valves are manufactured to NACE corrosion standards and material specifications required by major operators.
Offshore and deepwater applications require high-capacity relief without excessive back pressure or response lag. Our pilot-operated designs deliver reliable, stable relief performance across wide pressure and flow ranges. Capacity testing at operating conditions proves valve performance in actual service environment.
Hydrogen sulfide (H2S) service demands exceptional material selection and design rigor. H2S-rated valves use special stainless steels (duplex, super-duplex) and hardened internals to prevent sulfide stress cracking and stress corrosion cracking. We work with operators and major contractors to ensure valve certification meets your specific H2S exposure limits.
