SIMBOLOGIA-NEUMATICA-ISO-1219-1.pdf

Pneumatic symbols conform to international standards and include basic shapes, functional elements, flowlines, connections, and conditioners. Valve symbols indicate the number of ports and states through diagrams of the flow paths joined end to end. Common actuators include cylinders in various configurations and rotary motors. Three-position valves have a normal central position that varies the flow pattern. Operators can be manual levers or automated controls.

Thus, it is: z · The communication platform for fluid power in Europe. · The international umbrella organisation for national fluid power The international umbrella organisation for national fluid power associations in Europe. z Through the 18 national associations which are member of CETOP, all well known companies in Europe belong to the European Committee. Many of these companies are leading fluid power manufacturers and Many of these companies are leading fluid power manufacturers and major players in the international markets. z CETOP represents more than 1,000 companies - mainly manufacturers, but also some dealers - with almost 70,000 employees and a market value of abo t 13 billion EURO These acco nt for a er high proportion of of about 13 billion EURO. These account for a very high proportion of companies active in these fields - 80-90% in most countries.

Valve symbol structure
Valve symbol structure Valve symbol structure z The function of a valve is given by a pair of l t d b t k 3/2 numerals separated by a stroke, e.g. 3/2.. z The first numeral indicates the number of main ports. These are inlets, outlets and exhausts but ports. These are inlets, outlets and exhausts but excludes signal ports and external pilot feeds. z The second numeral indicates the number of t t th l hi states the valve can achieve.
