Pneumatic Automation

Posted by Toni - August 7th, 2016

The valves of directional control are the responsible ones for directing the air flow for the actuators and specific parts of the pneumatic circuits where they assume the function of selector or of cut. Constructive characteristics the valves of directional control can be of the type piston (spool) or accent (poppet). Too much constructions derive from these two main characteristics. Principle of Functioning the valves can be of direct or indirect action, with muscular, mechanical, pneumatic or electric command. Symbology the valves of directional control possess a variety of symbols that joined form and identify its function quickly. The symbols presented in this work meet in compliance with NBR 10238.

A tap, that is constant part in our day the day is a valve of directional control. The taps meet closed, as in the figure below, exactly with the water of the plumbing entering for 1 it does not have water draining. The water only starts to flow off later that we act on manopla turning and moving away the internal prohibition from the accent, allowing then that the water flows off. The water only stops to flow off when new performance in manopla occurs, taking again the prohibition to the meeting of the internal accent and blocking the water ticket.
