Non Slam Nozzle Check Valve EDRV DN 80 – 600 PN 10 – 40 Body: EN-JS1025, EN-JS1030 Coating: Epoxy, Enamel Minimum pressure loss through optimised flow cross-sections Flow-optimised valve disc and valve sealing ring Optimum hydraulics with short closing path to minimise water surge Wide area of application due to compact form, any possible assembly position and adjustable spring strength Product Description The Innovative Non-Return Valve For Maximum Economy An optimised flow cross-sectional area as well as a valve disc and valve stem gasket designed for minimum flow resistance ensure minimum head losses with the ERHARD non slam nozzle check valve. This enables highly economic operation especially in pumping stations. Valve disc, spring and closing travel have been engineered in such a way [2] that the ERHARD non slam nozzle check valve reacts that quickly even in highest flow delays (e. g. in a vertical line) that only minimal return flow velocities occur, with the flow being gently slowed, thus reducing water hammers to a minimum.
