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
