Double Seat Mix Proof Valves are used in the automated piping
systems which demand parallel operation of product and
cleaning cycles in order to optimize the economy of operation of
complex plants. As the name suggest “Mix-Proof” means no
mixing of uncongenial fluids, but at the same time allow
simultaneous processing of two different fluids through a single
valve with absolute safety. It has wide application in the food,
dairy, brewery, cosmetic and other hygienic process industries.
The 900 Series mix proof valve allows simultaneous operation of
two fluids with the help of Double Seat Design, creating a
chamber which isolates the fluid passing through the two bodies.
In case of seal failure of any individual seat, the fluid bleeds
down the leak detection port, directing the fluid to the bottom of
the valve, without letting the flow to getting mixed. Further, in
case of pressure surge, due to the localized increase in the line
pressure, the seat would be lifted, and allow the liquid to drain
out through the lower port, without disturbing the upper seat,
thus preventing intermixing of the two fluids. The valve is
equipped with the chamber cleaning feature, where the chamber
between the two seats can be cleaned independently, by
operating the correspond seat.
The self drainable spherical body is machined from forged acid
resistance Stainless Steel. The Spherical Shape offers
minimum resistance to the line flow, in turn offering minimal
pressure drop. The one piece compact construction of the valve
bodies permits space saving while valve installation. The open
yoke design ensures easy cleaning of the valve plug. All seats
and seals are made from FDA approved materials. Balanced
valve stems make the valves water hammer safe.

Working Principle
VALVE POSITION " CLOSED"
* Separation of Non-Compatible media to atmosphere.
* Eventual Leakages due to demaged seal will be dis charged to outside via leakage chamber
CLEANING OF THE UPPER SEAT VIA VALVE HOUSING.
* Upper valve disc lifted pre determined height to allow cleaning fluid into leakage chamber.
* Cleaning fluid flows across Seat to outside and cleans seals, seat, leakage chamber and drain pipe.
CLEANING OF THE LOWER SEAT VIA HOUSING.
* Lower valve disc lifted pre determined height to allow cleaning fluid into leakage chamber.
* Cleaning fluid flows across Seat to outside and cleans seals, seat, leakage chamber and drain pipe.
VALVE POSITION "OPEN"
* Lower valve Disc will be lifted and seals leakage chamber against upper valve disc and continues to full open position.
* The little amount of product leakage during operation of the valve in leakage chamber is externally drained
