Oil & Gas
Pipeline and process valves for upstream, midstream and transmission service: trunnion ball, gate and check valves engineered to API standards with fire-safe and emergency-shutdown capability.
From the wellhead to the transmission pipeline, oil and gas service demands valves that combine high-pressure integrity, full-bore flow and rapid, reliable shut-off. These are safety-critical components: a single valve may have to isolate a high-pressure pipeline in seconds during an emergency, and hold tight under fire.
Purple Valves supplies trunnion-mounted ball, gate and check valves engineered to the API standards that the industry depends on, with full-bore designs to minimise pressure drop, fire-safe construction, and provisions for automated emergency shutdown.
Common Challenges in Oil & Gas
High pressure and full-bore flow
Pipeline service needs full-bore valves that minimise pressure drop while sealing reliably at high pressure. Trunnion-mounted ball designs carry the load and keep operating torque low even at large sizes and high classes.
Fire-safe and emergency shut-off
Hydrocarbon service requires valves that maintain integrity in a fire and close fast on demand. Fire-safe seat and stem design plus actuator readiness are essential for ESD duty.
Sour service and harsh environments
Corrosive and sour fluids attack standard materials. NACE-compliant metallurgy, corrosion-resistant trim and robust sealing protect against H2S cracking and extend service life.
Recommended Valve Types
Trunnion-Mounted Ball Valves
The pipeline standard: full-bore flow, low torque and double block-and-bleed capability for transmission and process isolation, designed and tested to API 6D.

Check Valves
Dual-plate and swing check valves prevent reverse flow on pipelines, pumps and compressors, protecting equipment and maintaining line integrity.
