The APV DELTA DA3+ is a
modern, ultra-hygienic double seat mixproof valve with seat lift function,
designed to meet the challenging demands of hygienic processing.
The valve is the result of
continued development and improvement of its preceding models and has proven
its reliability in many different applications for many years. One of its
features is that after upper or lower seat lifting during CIP pipeline
cleaning, spraying of the leakage chamber is not imperative due to the
efficient cleaning of the leakage chamber being carried out by the seat lift
function.
