Gate Valves
Zhengzhou High Pressure Valve Factory publishes a separate gate-valve series; request the exact model rather than applying the company overall pressure range to every valve.

The own catalogue has a dedicated safety-valve series; a project-specific set pressure and applicable documentation must be confirmed for the actual offered unit.
Identify the protected equipment, fluid, required relief duty, inlet and discharge arrangement and project documentation. Request the selected safety valve and application-specific sizing and installation documents rather than assuming a universal setting or rating. Request the current catalogue or drawing for this item, and confirm the offered configuration and supporting documents with the company before specifying an order.
