The 3″ 5000 PSI Ручной Reset Relief Клапан 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.
