BS ISO 10094-2:2010 Pneumatic fluid power. Electro-pneumatic pressure control valves. Test methods to determine main characteristics to include in the supplier's literature

In pneumatic fluid power systems, power is transmitted and controlled through a gas under pressure within a circuit. When pressure tracking or pressure regulation is required, electro-pneumatic continuous pressure control valves can be used to track a variable set point with low tracking error or to maintain the pressure of the gas at an approximately constant level.

These control valves continuously modulate the pneumatic power of a system in response to a continuous electrical input signal and link the electrical input value to a proportional pressure value.

It is therefore necessary to know some performance characteristics of these electro-pneumatic continuous pressure control valves in order to determine their suitability.

BS ISO 10094-2 specifies the test procedures and a method of presenting the results concerning the parameters which define the main characteristics to be included in the supplier's literature of the electropneumatic continuous pressure control valves, conforming to BS ISO 10094-1.

The purpose of BS ISO 10094-2 is:

  • To facilitate the comparison by standardizing the test methods and the presentation of the test results, and
  • To assist in the proper application of these components in compressed air systems.

The specified tests are intended to allow comparison between the different types of continuous pressure control valves; these are not production tests to be carried out on each manufactured product.
