Sir,
I would like to use the PM1-40 OR PM1-50 OR ( PM3-40/PM3-50) valve for the following WATER CHILLING APPLICATION @ 1 DEG C OUT ,

1 the capacity of the plant is 45TR @ Nh3 gas, evaporation (sst) suction temp (-4 degC) , condensing (sdt) temp 38 degC,
2.Application is chilled clear water: in temp to chiller is 5 deg c & out from chiller is 1deg. Also note that the flooded chiller used in this application is welded cassettes heat exchanger WPHE.

We would like to maintain the constant evporative pressure (& hence the temp) in the WPHE to avoid the freezing of clear water in the channels when it comes out from the WPHE

Pl suggest which pilot operated valve we should use with PM-1-40 ? ( CVP/CVPP/CVT/CVQ/CVC ?)


Can you help me ?
