Discharge pressure: the valve inlet pressure reaches a predetermined height when open. The upper limit discharge pressure required to obey the requirements of the relevant standards or specifications country. Over pressure: discharge pressure and valve opening pressure difference between the price of steel, usually expressed as a percentage opening pressure. Shandong Everbright Valve Co., Ltd. specializing in the production valve manufacturers, welcomed the new and old customers to order our products! When the equipment or pipeline pressure or temperature exceeds a set pressure relief valve Weifang cast steel valves, pressure relief or cooling automatically open to ensure that equipment and the pipeline medium pressure (temperature) is below the set pressure (temperature), protective equipment and Pipeline work properly cast steel valves, prevent accidents, reduce losses. Shandong Everbright Valve Co., Ltd. specializing in the production valve manufacturers, welcomed the new and old customers to order our products! Theoretical displacement: is equal to the cross-sectional area of ??the flow path and valve nozzle flow area ideal computing emissions. Discharge coefficient: actual displacement and the theoretical displacement ratio. Rated discharge coefficient: coefficient of discharge and reduction coefficient (0.9) of the product.
