Solenoid Valves

Scaling Down Solenoid Valves Without Reducing Flowrates

Over the course of their long existence solenoid valves have developed slowly but continuously so that they are opening up new fields of application. Today they are a central element in controlling fluids in a broad spectrum of different applications. One of the newer areas of application is in the life sciences. A new actuation technology now allows a significant reduction in size with no loss of performance.

Measurement Technology for Potentially Explosive Areas

How to Design Intrinsically Safe Circuits

The intrinsic safety (Ex i) type of protection has established itself worldwide in the field of measurement and control technology in systems with potentially explosive areas. For one thing, it is much more cost-effective when it comes to construction when compared to other types of protection. For another, it allows for maintenance work and modifications during operation. Moreover, it is also possible to use simple electrical equipment without special approval.

Multi-Diaphragm Pumps

Industrial-scale Preparative Liquid Chromatography Specialist Chooses Multi-Diaphragm Pumps

Separlab, a Czech specialist in high-performance liquid chromatography (HPLC), has standardized on Wanner seal-less Hydra-Cell multi-diaphragm pumps in its industrial-scale systems, using them to deliver solvents for the mobile phase and to inject sample mixtures. Learn why the company prefers such “specialists” over single-diaphragm and piston-plunger pumps in these applications.
