【Abstract】 In this paper, a novel pneumatic relief valve wi th high pressure and large flow capacity is presented, its structure characteris tics are also presented. And then the valve’s performances are investigated by t heory analysis and experiments. Because the valve uses a single stage poppet and a rubber membrane with corrugations and air cushion bearing, it shows rapid res ponse, higher pressure control precision and good adaptability to a large range of working pressure. This valve has been used in a projecting system.更多还原
