White Paper: Piston spool valves and poppet valves A technical comparison of available solenoid valves

Why should you choose your valves carefully?

 

The increasing demands placed on valve technology in recent years have led to a formidable extension of the range of available technologies and valve types, models, and properties. The most commonly used are poppet valves and piston spool valves. Nowadays, there is hence a much wider choice of customised valve technology to successfully plan a project. However, choosing the right parts for the application at hand requires comprehensive knowledge and an accurate appraisal by the consulting engineer or technician. This White Paper is intended to offer you a brief overview.

 

This white paper contains information on:

 

  • An introduction to valve technologies
  • Poppet valves, piston spool valves and the cartridge principle – what you need to know
  • Which valve type suits you best? A valve selection aid

Bistable valves in safety-related applications. An example. Technical report TR-300003

Summary:
Due to their bistable characteristics, bistable valves in certain applications present the user with tasks that seem to be difficult to solve. This application example is to show how a solution can be developed systematically taking the various operating states and operating transitions into account. Considering the various hazards in the various operating statuses of the machine appears a sensible approach to finding the solution. They require chronologically successive, different reactions of the safety circuit to implement the required protective measures.

Festo AG & Co. KG bistable valves for safety-related applications Technical Report - TR-300004

Summary:
Technical Reports 2 and 3 [1-2] and DGUV Information FB HM-076 [3] already explained the circumstances under which bistable valves can be used in safety-related applications. The present report links these reports to the current product portfolio of Festo AG & Co. KG. The suitability of the bistable valves listed for safety-related applications can be confirmed taking the previous series of technical reports and respective technical documentation of the individual components into consideration.
