Technical Guides
Valve Storage and Preservation Before Installation
A field guide to valve storage and preservation: what damages stored valves, how to protect ends and internals, shelf-life rules for elastomers and the pre-installation checklist.
Technical Guides
Valve Spare Parts Strategy: What to Stock and What to Order Per Project
A practical strategy for valve spare parts — wear parts versus long-lead items, commissioning spares versus two-year spares, storage life and contractual clauses.
Technical Guides
Valve Partial Stroke Testing: Proving ESD Valve Integrity Without a Full Trip
A practical guide to partial stroke testing of emergency shutdown valves — principle, detectable failure modes, SIL implications, process risk and record keeping.
Technical Guides
Three-Way and Four-Way Diverting Valves: Design and Application Guide
A practical engineering guide to three-way and four-way diverting valves, covering flow path geometry, sealing, actuation and the specification mistakes that cause field problems.
Technical Guides
Vacuum Service Valves: Design Requirements Most Engineers Overlook
Why a valve that passes pressure testing can fail in vacuum: stem leakage, outgassing, seating under reverse load, leak-rate metrics, and the design details vacuum applications demand.
Technical Guides
Sulfuric Acid Service Valves: Materials, Sealing, and Safety Considerations
A materials-and-sealing guide for sulfuric acid valve selection, covering the counterintuitive corrosion behavior of H2SO4, the roles of Alloy 20, high-silicon iron and linings, and the safety case for plug valves.
Technical Guides
Chlorine and Chlor-Alkali Service: Valve Material Selection Guide
Why dry chlorine and wet chlorine demand opposite material strategies, how to pick body and seal materials across the chlor-alkali plant, and the cleaning and safety practices that keep valves leak-free.
Technical Guides
Water Hammer and Surge: Valve Closure Time and Protection Strategies
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
District Heating Valve Selection: High-Temperature Water and Thermal Cycling
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
Desalination Plant Valves: Materials and Designs for Seawater Service
A practical materials and design guide for valves in seawater desalination plants, from intake to brine outfall across MSF, MED, and RO processes.
