Single-body valve for regulating/interrupting the flow in a hydraulic circuit, comprising a valve body (101) extending along a first direction of flow (X-X) and comprising an axial duct (101a) with opposite openings (101b), two branch ducts (102) extending and arranged opposite each other in a second direction (Z-Z) different from the direction of flow; an internal partition (103) which divides the axial duct (101) into an upstream part M and a downstream part V communicating with each other via an aperture (103a); a first controlled-operation valve (200), the closing member of which can be actuated in both senses from a position for opening the aperture (103a) of the longitudinal duct (101a) into a position for varying/closing the said aperture, and vice versa; a second manually operated valve (300) which is situated opposite the first valve and the closing member (301) of which can be actuated in both senses of the same direction from a position for opening the aperture (103a) of the longitudinal duct (101a) into a raised position for closing the said aperture, and vice versa..

+ a container body (10), preferably made by means of extrusion,+ a series of first light sources (21;221) and a series of second light sources (22;222), arranged on at least one printed circuit board (20;220a,220b);+ power supply means (50,51) for supplying power to the light sources (21,22;221,222);+ diffusion optical means (30) for diffusion of the light emitted by the first light sources (21;221);+ concentrating and/or directing optical means (40) for concentrating and/or directing the light emitted by the second sources (22;222)said container body (210) has a first and a second longitudinal seats (213,211), wherein the first light sources (221) are arranged on at least one first printed circuit board (220a) and the second light sources (222) are arranged on at least one second printed circuit board (220b), the at least one first printed circuit board (220a) and the at least one second printed circuit board being respectively housed in the first and second longitudinal seats (213,211) of the container body (210), and:the second longitudinal seat (211) of the housing body (212) is in the form of an "open C", with a curved rear arm (211a) and a curved front arm, connected by a base (211b),

Earthquake-resistant roofing system comprises one or more pitches (100) for roofing an upper exterior area (2) of a supporting structure (1), each extending in length parallel to a longitudinal direction (X-X) and in width parallel to a transverse direction (Y-Y) and comprising a layer of insulation (110), comprising one or more panels of insulation material and transverse battens (112) rigidly joined to the panels (111) for fastening to the supporting structure by means of first fasteners (113), an aeration layer (120), comprising of transverse laths (121) of aeration, each overlapping in a vertical direction and attached to one of said laths (112) of insulation, longitudinal laths (130) of anchorage, arranged orthogonally above the laths (121) of aeration at predetermined intervals in the transverse direction and attached to the transverse laths (121) of ventilation by fasteners (131). A roofing membrane (140) comprises a plurality of roofing elements (141) arranged in longitudinal rows and transverse columns above the anchor laths and defining an outer lateral perimeter of the pitch roofing membrane (100). At least all of the perimeter roofing elements (141) arranged along the (144,145) lateral perimeter of the pitch roofing membrane are anchored to an underlying anchor lath (130) by a respective fastener (142).
