Abstract
A safety relief valve especially suitable for connection in a pressure gas system for beverage dispensing equipment has a body that defines a vented cylindrical valve cage and a coaxial annular valve seat at one end of the cage with an annular seating surface that faces axially into the cage. A pressure chamber in the body is communicable with the valve cage through the valve seat. A valve element, coaxially movable in the valve cage, is biased towards engagement with the seating surface and presents a pressure surface to the pressure chamber. Opposite tubular nipple portions of the body have bores that are symmetrical to the valve cage axis and communicate at their inner ends with the pressure chamber, said inner ends being separated by a baffle which is symmetrical to said axis and projects into the pressure chamber from the side thereof opposite the valve seat. Pressure fluid flowing into either nipple is deflected by the baffle towards the pressure surface to impose impact pressure thereon, hence the valve cannot be connected backwards.
