Description

• Two independent seat sealing arrangements and seperation cavity with discharge to atmosphere. • Upper and lower valve shaft can be cleaned as well • No sump or dome due to the smooth ball shaped valve housing design. This ensures easy cleanability and short cleaning time • Safe against water hammer. Balanced upper and lower valve shafts maintaining the integrity of the valve even in case of a water hammer. • Minimized operating leakages. The limited residual fluid trapped between the seat and the valve shafts drains off to the atmosphere via the leakage cavity only when the valve closes. • The neutral area between the two valve seats is efficiently cleaned by means of a built-in spray nozzle • No gap (crevice) between seal and seal groove where product could get trapped. Identification numbers are marked on profile seals prevent the installation of incorrect seals. • Compact and ergonomic design facilitates installation and maintenance and the footprint, especially for the manifolds, is reduced • The DELTA DE3 valve family is designed to be NC (Normally closed) • No compressed air required for service. • All seat seals, as well as shaft seals are identical, which means that inventory costs can be kept at a minimum • Seal sizes are grouped over several valve sizes, for example same kit for group I (DN40, 50, 65 + 1,5”, 2”, 2,5”, 3”) group II (DN80, 100 + 4”) and group III (DN125, 150 + 5”, 6”) • The valve actuator is completely maintenance free and covered by a five-year APV guarantee FAMILY CONSISTS OF • The standard DELTA DE3 valve • The change-over version DELTA DEU3 • The tank-outlet version DELTA DET3
