Applications
◆The mixproof valve is widely used in fluid processing technology,
especially in the beverage, dairy industry applications.
◆Mixproof valve is a high degree of double-seal valve. Through the
interface between two fluids, this system can be implemented in two
body synchronization process, preventing the possibility of
contaminating materials. leakage chamber and leak detector is self-
cleaning by valve seat.
Operating principles
● Lift type mixing proof valve is remotely operated by compressed
air. It is normally closed before running.
● The mixing proof valve is constructed with two independent plugs,
which will form a leakage chamber to atmosphere under normal
working status. When occasional failure causes leakage happen,
medium will flow into the chamber and be diacharged at the outlet
port.
● The leakage chamber is closed when the valve is operating, the
medium can flow through one pipeline to another. This valve can be
clean in place. Many options of CIP and SIP combination are
available to users.(Refer to cleaning sterilization function
options)
● Clean system can clean the upper, lower stem and leakage chamber,
which ensure the valve to be high hygienic. Effectively cleanig
system makes the fluid that special for (CIP) clean in place
directly wash all the inside calve body, it takes shorter time than
common cleaning system.
● Another beneficial of the high cleaning system is that the lift
type mixing proof valve can be applied to aseptic processing. If
user’s steam into CIP pipeline, the system will constitute a shield
that can isolate air.
