EMERSON ? ASCO Angle Seat type Pneumatic Valve, ISO 2in, 2.5 bar

A range of high speed voltage comparators from Texas Instruments featuring response times of less than 200 ns. The range includes ultra-fast devices such as the TL3016 and TL3116 which have complementary (differential) outputs and typical switching times of 10 ns or less.

The Asco Vanne 290 series next gen features a G or RP connection, combining ISO 228-1 and ISO 7-1 standards. It is a 2-way valve with a normally closed function and a nominal diameter of 50mm, equivalent to 2 inches. The valve includes a plastic actuator with a piloting connection of 63mm and G1/8 inch. It has a threaded body and is constructed with a stainless steel body and disc seal.

Comparators, Texas Instruments

Texas Instruments’ range of voltage comparators includes not only conventional single, dual and quad comparator packages but also window comparators and over- & under-voltage supervisors.

Although comparators and operational amplifiers are superficially similar devices their operation in practical applications is very different. Op amps are intended for linear operation accompanied by suitable feedback whereas comparators are tailored for rapid switching and generally operated in open-loop mode. Dedicated voltage comparators have significantly shorter propagation delays and are capable of faster response times under saturated conditions. Most comparators are also more tolerant of high differential input voltages and many have open-collector outputs allowing parallel operation with other devices.
