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. Shandong Everbright Valve Co., Ltd. specializes in producing valve manufacturers valve manufacturers, welcomed the new and old customers to order our products! 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 the opening pressure difference between the high temperature and high pressure valves, the opening pressure is usually expressed as a percentage.
