Valves for Mining Tailings and Paste Backfill Lines
How to specify valves for abrasive, high-density tailings and paste backfill duty, from erosion and velocity management to failure prevention and safety.
Pump Valve Book Editorial Team
The Pump Valve Book editorial team compiles application notes, standards references and procurement guidance on valves, pumps and actuators for plant, maintenance and project engineers.
Technical Guides
Valve Erosion in Multiphase and Particle-Laden Flow
A practical engineering look at why valves erode in sandy, multiphase service, which parts fail first, and what design and operating measures actually extend service life.
Technical Guides
Valve Installation Orientation: Why Stem Position Matters
Stem-up is not a stylistic preference. This article explains what happens to packing, actuators and valve cavities when valves are mounted upside down or sideways, and how to get orientation right the first time.
Technical Guides
Flange Face Finish and Gasket Seating for Valve Connections
Most valve leaks start at the flange, not the valve. Here is how face finish, gasket choice and seating stress interact — and what to check before you torque.
Technical Guides
Bolting Torque and Tightening Sequence for Valve Flanges
Torque is where flanged joints are won or lost. This article covers the load path from wrench to gasket, cross-pattern tightening, lubrication factors and hot torqueing practice.
Technical Guides
Hydrodynamic Noise in Liquid Service Valves: Causes and Mitigation
Liquid valve noise is a symptom, not a nuisance. Understand the turbulence, cavitation and flashing behind it — and the velocity, trim and piping measures that bring it under control.
Technical Guides
Seat Lapping and Grinding: Restoring Metal-Seated Valves
A practical guide to lapping and grinding metal-seated valve seats, from compound selection and damage assessment to helium and bubble leak verification.
Technical Guides
Valve Flushing and Commissioning Cleanliness
How to protect valves from pipeline debris at startup — flushing strategy, temporary spools and strainers, flow direction, and commissioning acceptance checks.
Technical Guides
Ball Valve Seat and Seal Replacement in the Field
How to replace ball valve seats, seals, and packing in the field safely and correctly, from cavity depressurization through torque testing and leak verification.
Technical Guides
Control Valve Recalibration: When and How to Do It
A practical guide to control valve recalibration: signals, zero and span checks, auto-stroke calibration, deadband testing, tuning, and when to schedule the next one.
Technical Guides
Valve Maintenance Intervals: Building a Realistic Program
How to replace one-size-fits-all valve maintenance schedules with criticality ranking, condition-based triggers, and a realistic action matrix your team can sustain.
Technical Guides
Reading a Valve Datasheet Line by Line for Procurement
A practical line-by-line walkthrough of a valve datasheet for procurement teams, showing what every field means for cost, lead time, and bid evaluation.
