PRODUCT DESCRIPTION
Tecofi PVS4140S Cast Iron Air Release Valve
PVS4140S is a Tecofi (France) single-chamber, single-function air release valve with a GGG40 ductile iron body and a DN25 (1″) BSP female thread, used to vent or purge air pockets in water pipelines. The datasheet states PN10/16 and a maximum working pressure of 16 bar. This page covers code PVS4140S only; its sibling PVS4150S (separate page) has the same size and materials but a different pressure class (PN25, 25 bar).
