extended bonnet
How to specify and install valves in cold service: condensation and ice formation, insulation and vapor barrier design, extended bonnets, ice seizure of stems and actuators, coating selection against CUI, and maintainability.
slurry valves
Knife gate and conventional gate valves compared: pressure ratings, size ranges, solids handling, sealing design, standards, weight and cost, maintenance, and where the selection line falls.
duplex strainer
How to read differential pressure across pipeline strainers, clean baskets safely, inspect mesh damage, and build a maintenance record that predicts fouling.
water hammer
A practical review of check valve failure modes — disc separation, seat erosion, flutter fatigue, slam and water hammer — with root causes, symptoms, and prevention strategies.
air consumption calculation
How to calculate air consumption for pneumatic valve actuators, size supply piping, receivers and compressors, and protect ESD stroke times from an undersized instrument air system.
valve noise
How aerodynamic noise forms in gas-handling valves, how IEC prediction methods frame the problem, and which mitigation routes — low-noise trim, diffusers, pipe treatment — actually work.
valve seat selection
A practical comparison of soft seat materials for valves — PTFE, PEEK, PCTFE, nylon and filled grades — covering temperature and pressure limits, cold flow, chemical compatibility, and failure modes.
News
New butterfly valve designs announced this year target higher pressure classes, longer seat life and faster automation — signaling continued investment in the workhorse valve.
News
Trade data for the first three quarters of 2026 shows ball valve exports redistributing across Asia, with India and Vietnam gaining share in mid-range products.
News
Operators are holding capital discipline into 2027, which means fewer megaprojects but a deep, steady stream of maintenance and brownfield valve work.
News
The autumn and spring turnaround seasons compress a year's worth of isolation and control valve work into weeks, straining supply chains that must plan months ahead.
News
Copper expansion projects in Chile and Peru are ordering slurry valves, knife gates and pinch valves in volumes that reward specialist manufacturers.
