How to Prepare a Valve Data Book for Project Handover | MDR, Test Records, and Certification Compilation
A Valve Data Book is the controlled documentation package that valve manufacturers compile for project handover in EPC oil and gas, petrochemical, power, water, and industrial pipeline projects. It is the primary evidence file for each delivered valve. A complete Data Book links the purchase order, valve tag, serial number, material heat number, inspection records, […]
How to Procure Industrial Ball Valves for Power Plant Projects | Bid Package and Vendor Qualification
Power plant ball valve procurement depends on process duty, pressure class, material compatibility, inspection evidence, certification scope, and delivery risk. A reliable procurement package converts these requirements into measurable bid documents, verifiable vendor qualification criteria, and enforceable inspection controls. In large thermal power projects, total valve quantities can reach tens of thousands when main process […]
How to Read a Valve Torque Curve | Break Torque, Run Torque, and Safety Factor Selection
A valve torque curve is the main reference for actuator sizing. If the curve is read from only one value, the selected actuator may fail to open the valve, stop before full travel, or close without enough torque to achieve the required seat tightness. The opposite problem is also common: if a catalog value is […]
How to Select Valve End Connections for Industrial Pipelines | Flanged vs Buttweld vs Threaded
The choice of valve end connections in industrial pipelines directly affects sealing reliability, maintenance access, installation cost, and long-term safety. This article explains how to select flanged, buttweld, threaded, and clamp-type valve end connections for chemical plants, refineries, steam systems, hydrogen service, utility lines, and sanitary processes. The selection logic is based on commonly used […]
