20130019955 | DIFFERENTIAL PRESSURE VALVE WITH REDUCED SPRING-SURGE AND METHOD FOR REDUCING SPRING SURGE - Disclosed is a differential pressure valve comprising: a valve body, the valve body having at least one flow inlet and one flow outlet: at least one shutter, the shutter being movable between an open position and a closed position under a differential pressure across the valve; at least one flow passage from the flow inlet to the flow outlet; at least one biasing member configured to bias the shutter towards a closed position so as to block the flow passage through the flow inlet. The biasing member is a non-linear biasing member. | 01-24-2013 |
20140338761 | AUTOMATIC VALVE WITH INTERCHANGEABLE SEAT PLATE - An automatic valve comprising a valve seat with first gas flow passages extending there through, and a valve guard having second gas flow passages extending there through. Sealing rings are arranged between the valve guard and the valve seat. A removable seat plate is removably connected to the valve seat and is provided with apertures matching with the first gas flow passages of the valve seat. The sealing rings are resiliently biased by resilient members against the removable seat plate to close the valve. The seat plate and the rings are made of non-metallic material. | 11-20-2014 |

20150044081 | AUTOMATIC VALVE WITH A SPRING HOLDER RING - An automatic valve including a valve seat having first gas flow passages extending there through and a valve guard having second gas flow passages extending there through. The valve further comprises at least one shutter member movably arranged between the valve guard and the valve seat, at least one set of spring members biasing the at least one shutter member towards a closed position in sealing engagement with the valve seat to close the first gas flow passages, and at least one spring holder ring provided with a plurality of spring retention seats. Each spring member of the set of spring members is partially housed in a respective spring pocket formed in the valve guard and retained in a respective one of the spring retention seat. | 02-12-2015 |
