IMPORTANT: To properly operate and maintain your BAYCO 2180 & 3180 air relief valve the following instructions

are provided. Please read with care as improper handling or maintenance may cause a hazardous condition.
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.
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 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.

CAUTION: Do not modify your 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.

Installation:

 Prior to installation, clean any dirt or foreign matter from connection surfaces.
 Install Air Relief Valve in positions ranging from vertical (o deg.) to horizontal (90 deg). The opening

pressure will be reduced if the valve is not mounted vertically. Do not install valve in inverted position.

 Install Air Relief Valve with exhaust area positioned so exhaust vents safely (preferably down).

“Downward venting” prevents dirt or debris from entering the valve during travel.

 Threaded versions only, Removable thread locking compound is recommended for mounting.
 Threaded versions only, Thread the valve into place by hand and tighten using a crescent wrench (or

equivalent) across the hex flats.

 Victualic grooved, and Cam & Groove connection models come with a lug for attaching a security chain.

Care & Handling: Bayco air relief valves are tested at the factory and are in proper working condition when shipped.

Air Relief valves are designed to be tough and to provide long service with reasonable care and handling.

Operation & Maintenance Instructions:

 Weekly visual inspection of the valve is recommended
 Ensure that the valve body and exhaust vents are kept clear of build up.
 Ensure that exhaust vents remain clear of all obstructions.
 Inspect the valve regularly to ensure connection tightness. Excessive blower vibration may cause valve to

loosen over time.

 The Bayco Air Relief Valve is assembled with tamper resistant screws and is pre-set at the factory to

customer requirements. Any attempt to disassemble or adjust settings for any reason will void the
manufacturer’s warranty.
