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
Trim material decides how long a control valve holds its characteristic. This guide compares hardfacing, tungsten carbide, 17-4PH, and surface-hardened 316 against the ways trim actually fails.
Technical Guides
A blowout-proof stem is a small design detail with a large safety consequence. This article explains the mechanism, the standards, and what to confirm before buying.
Technical Guides
Y-type, basket, and conical strainers look like simple accessories, but the wrong one costs pressure drop and pump damage. This guide matches design to duty.
Technical Guides
Butterfly and ball valves both isolate with a quarter turn, yet they behave very differently at the flange. This framework helps engineers pick the right one for the duty.
Technical Guides
One-piece, two-piece, and through-conduit knife gate valves solve different problems. This guide breaks down construction, seating, installation, and the service trade-offs behind each body style.
Technical Guides
Three check valve architectures, three sets of trade-offs in cracking pressure, slam behavior, size, and weight. A practical guide to matching the check valve design to the line — and avoiding the classic misuses.
Technical Guides
For high pressure drops, flashing media, or high-cycle control duty, the guiding architecture inside a globe valve decides whether it survives. Here is how cage-guided and top-guided designs compare.
Technical Guides
Gate valves and globe valves look similar on a P&ID but serve opposite purposes. This article compares flow characteristics, pressure drop, seating, and maintenance so you specify the right one.
Technical Guides
A working engineer's comparison of lubricated, sleeved, and eccentric plug valve designs, with guidance on sealing mechanisms, duty ranges, maintenance, and failure modes.
Technical Guides
A practical comparison of plug valves and ball valves in abrasive, solids-laden service, covering cavity behavior, sealing materials, torque, and selection logic.
News
Pneumatic rack-and-pinion actuator availability has normalized, though spring-return variants and special coatings still carry longer waits than catalog promises suggest.
Technical Guides
Every plant has a valve maintenance program on paper. The difference between paper and practice comes down to four design decisions made before the first work order.
