Abstract

Improvements in control valves, diaphragm, included in a single valve body, to perform control functions, in water treatment circuits, automatic with programmed regeneration skies, essentially characterized, by comprising supports (1), of single valves, fixed to the single body (2) of cast iron and whose valves, have neoprene membranes (3), which seal the body (1), against the single body (2), and in whose center have an axis (4), made of stainless steel, covered with teflon, on the opposite end of which is a rigid disk (5) with a washer (6), seat that seats closed, against a forged seat (7), made of bronze, fitted to the body (2), by means of an annular gasket (8), whose closing is promoted when through the hole (12), the distributor (14), of pressure to the membrane (3), through the corresponding flexible tube (13), promoting the axial displacement of the axis (4) and the pertinent one closing of the valve, thanks to the contact of the washer (6), against the forged seat (7), supported by the gasket (8), by presenting an annular gasket of square section (9), which contacts the disk (11), which in turn contacts the board (10); by comprising a box (15), which supports the distributor (14), of the control cycles; for presenting a port (16), for purging, in the single body (2).
