Complete replacement parts catalog for the OTECO 3″ 5000 PSI Manual Reset Relief Valve. This high-pressure safety valve is widely used in oilfield drilling, well servicing, and flowline operations for reliable overpressure protection. Our comprehensive parts inventory ensures fast turnaround on maintenance, repairs, and rebuilds to keep your operations running safely and efficiently.

Product Overview

The 3″ 5000 PSI Manual Reset Relief Valve is a critical safety component in high-pressure oilfield systems. When system pressure exceeds the preset relief setting, the valve opens to vent excess pressure. The manual reset feature requires operator intervention to reclose, ensuring that overpressure events are always acknowledged and investigated. This valve is rated for 5,000 PSI (345 Bar) working pressure with 3″ nominal flow path, making it ideal for high-volume flowline and manifold applications.
