2182 Air Relief Valves

To properly operate and maintain your Dixon Bayco 2182 air relief

valve the following instructions are provided. Please read with care

as improper handling or maintenance may cause a hazardous

condition.

Dixon Bayco air relief valves are designed and built to provide

accurate and consistent operation; however periodic inspection,

cleaning, and maintenance of these valves is required to ensure

continued trouble free service.

Dixon Bayco air relief valves consist of a spring-loaded poppet valve

that seals against a rigid annular valve seat. When the system

pressure reaches the valve opening pressure the poppet lifts and

system air passes under the poppet and out to atmosphere. When a

sufficient volume of air has been relieved the system pressure will

drop and the poppet will reseat.

When these valves are used in applications that subject them to

particulate laden air, there is potential for contamination of the valve,

larger particles such as grains, plastic pellets etc. can get trapped

between the valve seating surfaces. Applications involving fine

particles such as cement, fly ash, lime, flour, etc. can result in a

cementing of hardened product on the valve seat or poppet surface

can occur. These situations can prevent the valve from fully

reseating, prevent it from opening and can lead to early opening

or leakage from the valve.

To prevent this from occurring, we advise that air/vacuum relief

valves be regularly inspected, cleaned and maintained. At a minimum

the valve seat and poppet sealing surface should be inspected and

cleaned, and the small air vent hole in the top casting checked for

blockage. The inspection, cleaning, and maintenance should be

carried out with the valve removed from the system to a clean

environment.

Do not modify your Dixon Bayco air relief valve for any

reason. It can result in a hazardous condition due to operating

difficulties or operation malfunction. Disassembly or tampering

will void the product warranty.
