The APV DELTA DA3+ is a modern, ultra-hygienic double seat mix proof 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.
