RPTFE, TFM 4215, PPL, PEEK or metal seat - which is right for your steam ball valve? Learn how to select the proper seat material based on steam temperature, pressure, differential pressure and operating conditions.

Choosing between PTFE, PFA and FEP lining? Learn how these materials differ in chemical resistance, temperature capability and service conditions, and how to select the right lined ball or butterfly valve for your application.

L-port or T-port 3-way ball valve? Learn the key differences in flow patterns, applications, and selection to choose the right valve for your piping system.

When selecting an automated valve for an industrial pipeline system, many engineers and buyers compare pneumatic butterfly valves and pneumatic ball valves.Both valves use quarter-turn operation and can be equipped with pneumatic actuators for automatic on/off control. However, their different desig

Electric and pneumatic actuators are both widely used to automate ball valves and butterfly valves. Choosing between them is not simply a matter of deciding which actuator is "better."The right choice depends on five main factors: the available power source, required fail-safe position, operating sp

Learn the difference between Air-to-Open and Air-to-Close pneumatic valves and how they relate to Fail-Open and Fail-Close operation. This guide explains spring-return actuator behavior, common fail-safe applications, and how to determine the appropriate valve position when air or control is lost.
