Product Description
AVP
Boiler Blowdown Valve Packages
AVP valve packages take the guess work out of blowdown plumbing configurations. AVP’s are factory pre-assembled to meet your boiler application pressure requirements complete with the probe cross (probe not included) and correct pipe lengths between components. Make installations even easier using prefabricated option P and we will pre-wire and mount your controller.
Specifications
The specifications of your AVP will depend on the individual items selected. The total shipping weight will be the total of the two valves selected plus approximately 9 pounds (Option P will be more).
Note: Older style VP valve packages are not pre-assembled but use components covered in the specifications listed below.
Boiler Blowdown Requirement Calculation
A boiler’s blowdown configuration (timed or continuous) is determined by the blowdown requirement in pounds of steam per hour. Using the following information:
1. Boiler steam output H.P. X 34.5 = steam output/hour
2. Make-up of water in pounds/hour based on percentage of return condensate
3. Cycles of conductivity concentration
