1 MULTIFUNCTION SPOOL VALVES air operated and air operated G/-G - ISO 99/ subbase-mounted body /-/ Series Type ISO size MULTIFUNCTION Multifunction selector The multifunction selector is equipped with pilot selector seals (A) located between the body (B) and the covers (C), on both sides : pilot and. Each selector can be set on or positions. Rotating or turning it upside-down allows the following functions : - internal or to pilot or operators. - selection of the type of operator : air operated or -air pilot or. For this, it is only necessary to position one of the arrows of the selector into the notch matching the diagram of the required function (see below). Functions can be modifi ed at will.the valves are delivered with the selector pre-set on the position corresponding to the function requested on order (see table CHOICE OF EQUIPMENT). External supply enables the valves to be used with a fl uid pressure ranging from 0 to bar and with vacuum.

2 ISO 99/ SIZE SPOOL VALVES - SERIES Operating principle Blanking plate (with an air operated pilot) pilot Changing from an air operated valve to a differential valve An air operated valve can be changed into a differential valve by turning over the outside piston ring as shown in the diagram below (). Air operated Differential Manual operator using a tester (option) A manual operator can be equipped with a tester () by knocking the knock-out plug () out of the end cover. An air operated valve can be changed into a air valve by : - re-positionning the selector seal, - removing the upper blanking plate (side or ), - fi tting a selector seal if lacking, - adding a pilot valve on the upper part. A air valve can be changed into an air operated valve by : - removing the pilot valve, - fi tting a blanking plate on the pilot base (plate code : ), - re-positionning the selector seal. USE WITH UNLUBRICATED AIR This range of JOUCOMATIC valves will operate satisfactorily with lubricated air or unlubricated air and even with dry air, due to a sealing device which has been patented. Essentially, a "T" seal backed up by a cushioning or compensation seal. This arrangement of seals assures a minimum pilot pressure which will remain constant even after the valve has been stopped for a long period of time. When re-starting, the performance of the valve will be the same as during continuous operation. This important "non-stiction" characteristic assures satisfactory performance under all conditions.
