Applications
◆Pneumatic double seat valve is designed to meet when there are two
different product flows through the same valve, both guarantee to
prevent fluid mixing and be convenient for monitoring the working
condition.The valve is used in dairy products, beverages, beer, and
other high purity requirements of the process piping systems.
◆This valve is normally closed(NC) by remotely being controlled
through compressed air .This valve is companied with two small
pneumatic valves(Normally open) to monitor of the valve seal
leakage
◆Plue(upper stem inside of a changever valve) has two seals, which
forms a leakage chamber between each other. The leakage medium
flows into the chamber and discharges through detector valve.
Supplying air to actuator can make the valve clean in place. During
cleaning, fluid flows directly to the plug. This valve is
unsensitive to water hammer effect
Operating principles
●This valve is normally closed (NC), remotely controled through
compressed air . This valve is companied with two small pneumatic
valves, one for monitoring, another one for CIP.
● Plug (upper stem inside of a divert valve) has two seals which
form a leakage chamber between each other. The leaked medium flow
into the chamber, discharges through detector valve. Supply air to
actuator can make the valve clean in place (see figure 2).
● Under cleaning, fluid flow directly to the plug. This valve is
unsensitive to water hammer effect.
