INOXPA has launched new INNOVA Mixproof double seat valves for their P, S and T models. The physical and functional improvements aim to enhance performance, extend durability and reduce the environmental impact.
Some internal and external aspects of the actuators have been redesigned to achieve that objective.
The number of actuator variants has been reduced from 10 to 3 due to a new system of lanterns, which now have a measurement for each valve size and specific measurements for DIN and OD.
Internally, one of the piston’s runs has been significantly shortened, with the aim of reducing air consumption and shortening the lower seat’s opening and closing response time.The springs have also been improved, extending their durability, and all dynamic seals are now of the “quad-ring” type.
The upper and lower shafts open during CIP processes to clean the seals and internal part of the shaft, leading to a small amount of cleaning product flowing out, which is normally collected in the manifold tray. There are two reasons for reducing this amount of product to a minimum: product savings and pollution reduction.
