Valves for Oil and Gas and Petrochemical in Mexico — Cematic

The oil and gas industry demands valves with the highest level of reliability, pressure resistance, and compatibility with aggressive fluids such as crude oil, natural gas, condensates, H₂S, and hydrocarbon mixtures. At Cematic, we offer valve solutions for upstream, midstream, and downstream, with international certifications and materials designed for the most severe operating conditions in the sector.

We work with PEMEX plants, EPC contractors, oil service companies, and private petrochemical plants in areas such as Coatzacoalcos, Salamanca, Ciudad del Carmen, Tampico, and Veracruz. We understand the critical timelines of the sector and respond quickly.

Certified valves for the Oil & Gas industry

·       API 6D ball valves in WCB carbon steel, 316L stainless steel, and Duplex, with flanged connections ANSI 150 / 300 / 600 and RTJ.

·       Gate and globe valves for high pressure and high temperature in steam and process service.

·       Check valves (swing, wafer, and piston types) for backflow prevention.

·       Pressure relief valves (PSV / PRV) calibrated for pressure equipment protection.

·       Stainless steel solenoid valves for control of gases and corrosive fluids.

·       Control valves with digital HART positioner for closed loop in DCS.

·       Explosion-proof pneumatic actuators (ATEX / IECEx) for classified areas.

Available materials for Oil & Gas service

·       WCB carbon steel — non-corrosive fluids, high pressure

·       316L stainless steel — corrosive fluids and chlorides

·       Duplex / Super Duplex — high resistance to chlorides and H₂S

·       Hastelloy C-276 — acids and highly aggressive media

·       Seals in PTFE, VITON, Grafoil, and NBR according to process fluid

Standards and certifications

Our valves for Oil & Gas comply with the main international industry standards: API 6D (pipeline valves), API 608 (ball valves), ASME B16.34 (pressure-temperature), NACE MR0175 / ISO 15156 (H₂S service), ATEX / IECEx for equipment in hazardous areas, and PED certifications (Pressure Equipment Directive) for export.

Typical applications in the sector

·       Offshore platforms and extraction wells (wellhead valves)

·       Gas and crude oil transport pipelines (pig valves, line valves)

·       Petrochemical processing plants and refineries

·       Gas treatment units (scrubbers, separators)

·       Fuel storage and distribution terminals

·       Natural gas-fired power generation plants

Frequently asked questions

❓ Do the valves comply with NACE MR0175 for H₂S service?

Yes, we have valves in NACE MR0175 / ISO 15156 certified materials for service in hydrogen sulfide environments, common in sour wells and sour natural gas processes.

❓ Can you supply valves with ATEX actuators for classified areas?

Yes. We offer pneumatic and electric actuators with ATEX / IECEx certification for installation in Zone 1, Zone 2, and Division 1 / Division 2 areas according to the process area classification.

❓ Do you handle API 6D valves with Material Test Certificates (MTC)?

Yes, we can supply valves with EN 10204 3.1 and 3.2 material certificates, documented pressure tests, and inspection reports for projects that require them.
