Abstract
(EN)
Embodiments of the invention provide a normally open valve, a normally closed valve, and a combination valve. The valves include a valve body with an inlet coupled to a fluid supply line, an outlet providing a service flow of fluid, a vent venting to atmosphere, a lower piston, a lower diaphragm, and a mechanical valve actuator. The mechanical valve actuator includes an upper piston, an upper diaphragm, a pilot piston with a bore and a plunger, and a spring. The spring is positioned either inside the pilot piston for the normally open valve or inside the upper piston for the normally closed valve. The valves are actuated based on a control fluid entering a system pressure port and exceeding a pressure set point in order to either open or close the valve.

La présente invention concerne, selon des modes de réalisation, une vanne normalement ouverte, une vanne normalement fermée et une vanne combinée. La vanne comprend un corps de vanne doté d'une admission accouplée à une ligne d'alimentation en fluide, une évacuation fournissant un flux de service de fluide, un évent de mise à l'air libre, un piston inférieur, une membrane inférieure et un actionneur de vanne mécanique. L'actionneur de vanne mécanique comprend un piston supérieur, une membrane supérieure, un piston de pilotage doté d'un alésage et d'un poussoir, et un ressort. Le ressort est positionné soit à l'intérieur du piston de pilotage pour la vanne normalement ouverte, soit à l'intérieur du piston supérieur pour la vanne normalement fermée. Les soupapes sont actionnées sur la base d'un fluide de commande entrant dans un port de pression de système et dépassant un point de consigne de pression dans le but soit d'ouvrir, soit de fermer la vanne.
