This equipment is potentially dangerous with the possibilit y of serious personal injury
and property damage. Hauck Manufacturing Company recommends the use of flame
supervisory equipment and fuel safety shutoff valves. Furthermore, Hauck ur ges rigid
adherence to National Fire Protection Association (NFPA) st andar ds and insur ance
underwriter’s requirements. O per ation and regular preventative maintenance of this
equipment should be perform ed only by properly trained and qualified personnel.
Annual review and upgrading of safety equipment is recommended.

WARNING

A. GENERAL INFORMATION

The Hauck Adjustable Air and Gas Port Valves are a dependable, accurate means of controlling
the flow of air or gas to any variable pressure type of burner or system. Flow control may be
either manual or automatic. T hese valves are easily adjustable and designed to hold the desired
setting in either mode of operation. Each side of the valve is equipped with four drilled and
tapped mounting pads. This facilitates the installation of multiple valve units or an automatic
control system. These units are designed t o be used as efficient control systems, not as shutoff
valves.

B. RECEIVING AND INSPECTION

Upon receipt, check each item on the bill of lading and/or invoice to determine that all
equipment has been r eceived. A caref ul examination of all parts should be made to ascer tain if
there has been any damage in shipment.

If the installation is delayed and the equipment is
stored outside, provide adequate protection as
dictated by climate and period of exposure. Special
care should be given to all motors and bearings, if
applicable, to protect them f r om rain or excessive
moisture.

EXAMPLE:
Determine the corrected vol umetric flow rate in standard cubic feet per hour for a
PVS2A20 (2") adjustable port val ve f or propane gas at 100°F having an inlet
pressure of 15 psig and a pressure drop of 5 psig.
Using the equation:

1. From the standard flow curve for Natural Gas (Q137) at 27.7 "w.c. pressure

drop, determine the rated flow:

2. From the Pressure c orrection factor table, determine the pressure correct i on
factor: C

3. From the Temperature correction factor table, det ermine the temperature
correction factor: C

4. From the Specifi c Gravity correction fact or table, determine the spec i fic
gravity correction factor for Propane: C
Then,
