Technical Guides
An engineer's guide to water hammer and surge: why closure time matters more than closure speed, how valve characteristics shape the pressure transient, and which protection strategies actually work.
Technical Guides
A practical guide to valve selection for high-temperature water district heating networks, covering welded-body construction, buried installation, thermal cycling effects, and long-term sealing.
Technical Guides
A practical materials and design guide for valves in seawater desalination plants, from intake to brine outfall across MSF, MED, and RO processes.
Technical Guides
A field-oriented guide to valve materials and designs for geothermal brine, scaling, H2S/CO2 environments, and thermally cyclic wellhead service.
Technical Guides
How to select body materials, trim, and soft seals for anhydrous ammonia, liquid NH3, and the new green and blue ammonia value chain.
Technical Guides
A working explanation of the ASME B16.34 pressure-temperature rating system and how to choose the right valve class without over-buying or under-specifying.
Technical Guides
A practical guide to PMI methods, acceptance criteria, and purchasing clauses for verifying valve body and trim alloys before they reach your pipeline.
Technical Guides
What valve procurement teams need to know about EN 10204 material test certificates: differences between 2.1, 2.2, 3.1 and 3.2, certificate contents, PMI verification and traceability.
Technical Guides
How jacketed ball valves and other jacket designs keep sulfur, asphalt, resins, and molten media flowing — jacket types, pressure ratings, drainage, and a practical selection checklist.
Technical Guides
A buyer's and engineer's guide to RT, PT, MT and UT in valve manufacturing: applicable areas, defect types, acceptance standards, witness points, and how to specify NDT without disputes.
Technical Guides
An engineering comparison of bolted, welded, and pressure-seal bonnet constructions for gate and globe valves, with guidance on pressure class, emissions, and maintenance trade-offs.
Technical Guides
A practical engineering comparison of metal seated and soft seated ball valves, covering leakage classes, temperature and pressure limits, hardfacing options and actuator implications.
