Difference between "normal water valve" and "Chilled water Valve".

Difference between "normal water valve" and "Chilled water Valve".

Difference between "normal water valve" and "Chilled water Valve".


Can anyone please tell the difference between normal water valves and chilled water valves? is there really any difference technically?

Also normal valves like gate, globe, butterfly, check, ball, etc ..do these valves are also available in chilled water valves?

Thanks and regards

RE: Difference between "normal water valve" and "Chilled water Valve".

Never heard the term "Normal Water Valve." Many of the same valves can be used on chilled water, hot water, steam, oil, compressed gas, etc. Pressure and temperature limitations should be provided by the valve manufacturer.

RE: Difference between "normal water valve" and "Chilled water Valve".

It depends on the how the client/engineer/whoever defined the service. Typically a valve is just referred to by the system it's in. If it's a ball valve in a chilled water system, it's a chilled water valve. That same physical valve is likely installed in normal water service as well.

All valves have a temperature/pressure limit based on the materials/soft goods/design of the valve. For common chilled water systems (~35F) the valves may be identical to "normal" water service valves. Once you get into severely cold (cyrogenic) and/or high pressure applications, the valve designs will change.

Hi Arnold,

There is not a such thing as "Normal Water". It could be Potable (drinking) Water, Domestic (Hot) Water (usually the same as Potable but heated), Service Water, Cooling/Chilled or Heating Water (could be water or water/glycol mixture), Demineralized Water or Condensate Return (for steam boilers), Produced Water (from wells), Storm Water (rain run off), Fire Water (for fire protection system), Raw Water (from river or lake before it gets into water treatment plant), to name a few. You can call it with any name to identify service.


RE: Difference between "normal water valve" and "Chilled water Valve".

Most water valves should be good for all duties from 0C to at least 100C.

There might be some different seals more compatible with low temperatures but that's about it.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

RE: Difference between "normal water valve" and "Chilled water Valve".

Hi there,

From pressure/temperature prospective all piping material, valves, pipe fittings for water service is similar because of water is water. There are some differences though when you dig deeper for particular services.
For example, for Potable Water service it is used 304 stainless steel material (piping, fittings, valves) for above ground lines. For materials used in this service you have to specify additional compliance to NFS/ANSI 61 standard (low Lead content) for potable water service, because high Lead content may cause Lead poisoning.

Arn Seb,

The first thing to know is the service conditions to specify a valve. Example: pressure, temperature, fluid properties/conditions, corrosion etc.
Based on it, a valve data sheet can be created. the objective of the data sheet is the specify materials for both both and non-metallic so that it can work under the fluid service conditions.
As LI have stated, a normal valve can work for both 'Chilled" and "Water' service as the temperature range will be bewteen 0 -100 degrees C.
