ANSI B16.34, API 6D,API 6A Stainless Steel Forged Steel Ball Valve

Butterfly vs gate valve compared by loss coefficient, pumping energy cost, weight, torque and leakage class, with selection rules and datasheet data.

How solid, flexible and split wedges differ in sealing, thermal binding and misalignment tolerance, plus selection rules and RFQ data.

The backseat, the gland and the blowout-proof stem decide whether a gate valve leaks at the stem, and whether it can be repacked with the line still live.

A fire-safe valve must still isolate after its soft seat has burned away. What API 607 and ISO 10497 test, and what the certificate does not cover.

How to size pneumatic valve actuators: valve torque, safety factors, spring-return vs double-acting, air pressure, stroking time and fail-safe position.

What the sleeve actually seals againstA sleeve type plug valve has three parts in the sealing path: a metal plug with a through port, a moulded sleeve of PTFE or PFA that wraps the plug and carries its own matching port, and a metal body liner behind the sleeve. Nothing is injected and nothing is gr

Bronze, 90/10 cupronickel, duplex, super duplex and Monel in seawater: what pits, what erodes, and how to write the material call-out.

Why check valves slam, what the Joukowsky surge really depends on, and how to select swing, dual plate and spring-loaded checks by flow deceleration.

Y-type, basket and duplex strainers sized by open area ratio: mesh openings in micron, clean and dirty pressure drop, and why baskets fail on steam.

Wafer, lug and double flanged butterfly valves compared: bolting, dead-end service, removal, gasket faces and where each body style fails.

Triple offset butterfly valves seal metal to metal with zero rubbing travel. Compare offsets, torque curves and seat materials for high temperature duty.

API 609 stops at NPS 60, AWWA C504 at 72 in. What really governs a DN2000 butterfly valve: offsets, shaft deflection, velocity and six failure chains.

Bellows seal globe valves fail at year two, not year ten. Three limits: cycle budget, fouled convolutions, load path. ISO 15848-1 classes included.
