Abstract: A valve comprising a body with an inlet, an outlet and a passage fluidly interconnecting the inlet and outlet; a shut-off device of the passage, with an actuating member movable along a longitudinal axis; a hand operating device of the actuating member, for selectively opening or closing the passage, and comprising a support element and a rotating element with at least one contact surface configured for sliding along at least one ramped surface on the support element, or vice versa, so as to convert rotation of the rotating element into a translation of the actuating member; wherein the body comprises two arms extending longitudinally and diametrically opposed relative to the longitudinal axis, with distal ends holding the support element.

Abstract: A valve for a fluid, comprising: a body with an inlet, an outlet and a passage fluidly interconnecting the inlet and outlet; a shut-off device housed in the body and configured for selectively opening and closing the passage, the shut-off device comprising a main seat, a main closing element forming a channel extending there through and a pilot seat, a pilot closing element housed in the main closing element, a first compression spring, and a second compression spring; an actuating device of the shut-off device. The second compression spring is operatively mounted between the main closing element and the body and the first compression spring is stronger than the second compression spring.

Abstract: A regulator for compressed gas, comprising a body with a gas inlet, a gas outlet and a gas passage fluidly interconnecting the gas inlet and gas outlet; a pressure reducer with, in the gas passage, a shut-off device and a movable assembly operatively connected to the shut-off device and delimiting with the body a regulating chamber downstream of the shut-off device; a pressure relief device in the gas passage downstream of the regulating chamber; and a flow restriction in the gas passage upstream of the shut-off device, dimensioned for reducing the gas pressure at the gas outlet under a maximum pressure value when the pressure relief device is opened and the shut-off device is opened.

Abstract: A device for regulating the pressure of a compressed gas, comprising a body with a gas inlet, a gas outlet and a gas passage fluidly interconnecting the inlet and outlet; a mobile element carrying a shutter cooperating with a seat in the gas passage, the shutter and the seat forming a regulating valve; a hand-wheel operatively linked to a spindle rotatably mounted on the body; wherein the spindle is hollow and houses a spigot with a cam, the spigot being linked in rotation with the spindle and cooperating with a counter-cam spigot movable in translation but not in rotation relative to the body, and acting on the mobile element or on a shut-off valve for selectively shutting-off and opening the gas passage.
