The Key To Extending The Life Of Your Animal Drinking Valves
Avidity Science Drinking Valves are made from autoclavable 316 stainless steel and silicone rubber components, materials renowned for their resistance to chlorinated or acidified water found in animal watering systems. We have best practices for the care of our drinking valves which includes information for sanitization, sterilization, and storage of the valves whether they are integral to the cage, removable or integral to the manifold. These guidelines are key to extending the life of your drinking valves.
Overview: Sanitizing, Sterilizing, and Storage
This is a quick reference guide for valve care. Please see full disclaimers and recommendations in our Sanitizing, Sterilizing and Storage of Rack Manifolds, Drinking Valves and Recoil Hose operational guide (OP-000041). Please contact an Avidity Science representative for more information. These best practices for valves include information for:

PLEASE NOTE: Avidity recommends that removable valves are sanitized and sterilized separately from the rack and placed in a valve tray. This will ensure that the valves are properly sanitized/sterilized and reduces the risk of the valves and quick disconnect sockets being damaged. See Avidity Science guide OP-000041 for full details of this process or contact an Avidity Science representative for more information.

| OVEREXPOSURE Overexposure to sanitization agents. Avoid free chlorine levels higher than 20 ppm and no longer than 45 mins of exposure. |
EXCESS HEAT Do not exceed a sterilization temp of 149° C (300 ° F). |
IMPACT DAMAGE Impact damage from being poured out of a collection container in a holding vessel. The impact from falling can force in the valve stem into the body of the valve, damaging the diaphragm. |
DO NOT LAYER Do not layer or pile the valves on top of each other. Impact of layering can result in the valve stem being damaged and/or pushed through the diaphragm, which will render the valve inoperable. |
1) Sanitizing Removable Valves
Removable drinking valves can be sanitized in a tunnel washer or ultrasonic cleaner. Follow the appropriate instructions based on the cleaning equipment used by the facility.
Using Valve Washing Tray or Wire Basket
- Place the valves stem-side down in the slots of the Valve Washing Tray.
- Place the tray in the tunnel/cabinet cage washer.
- Store the sanitized valves in the trays until the valves are to be sterilized or placed into service. If the Valve Washing Tray is not used, an alternate method is to place the valves in a single layer in a wire basket before placing them in the washer.
EQUIPMENT DAMAGE: Do not layer or pile the valves on top of each other. The impact of layering can result in the valve stem being damaged and/or pushed through the diaphragm, which will render the valve inoperable.
|
Tunnel Washer |
Ultrasonic Cleaner 2. Place the valves in a single layer inside the cleaning basket. Do not stack the valves. 3. Fill the ultrasonic cleaner with clean water. 4. De-gas and start the ultrasonic cleaner according to the manufacturer’s instructions. 5. Place the basket into the ultrasonic cleaner and run the unit. During this period only the outside of the valve is cleaned. 6. Remove the basket from the ultrasonic cleaner and rinse the valves completely with clean water. |
2) Sterilization and Autoclaving
Do not use a vacuum cycle deeper than -15 in. Hg when autoclaving drinking valves to prevent damaging of shields, o-rings and diaphragms. After the valves are sanitized, place the valves in the autoclave the same way they were placed in the cage washer.
The following is a list of APPROVED and NOT APPROVED cold sterilants:
Cold Sterilants Approved by Avidity Science |

Valve Care Guidelines:
Easy Connect-To-Cage
1) Sanitization
Included are instructions for sanitizing the valves in a tunnel washer, rack washer, or ultrasonic cleaner. Follow the appropriate instructions based on the cleaning equipment used by the facility. Sanitizing and sterilizing of valve and cages should be based on standard operating procedures (SOP).
Tunnel/Rack Washer
1. Follow the appropriate instructions based on the cleaning equipment used by the facility.
2. A chemical sanitizing process may be used or a combination of high-temperature rinse with a chemically-treated solution.
- Free chlorine concentrate not exceed 20 ppm*
- Maintain a pH level of 5.0 pH or higher
- Maximum contact time of 45 minutes
- Non-Chlorine process pH level can be no lower than 2.6 pH
* Chlorine sanitizing solution must be changed weekly. Chlorine dissipates relatively quickly. Solutions older than one week will not effectively sanitize.
2) Sterilization/Autoclaving
After sanitizing the valves, follow these recommended autoclave cycles.
- Three (3) pulse cycles with a vacuum pull no greater than -15 in Hg
- Do not exceed a sterilization temperature of 149˚C (300˚F).
- Dry cycle vacuum DO not pull a vacuum deeper than -15 in Hg
The following is a list of APPROVED and NOT APPROVED cold sterilants:
Cold Sterilants Approved by Avidity Science |
Cold Sterilants NOT Approved by Avidity Science |
|
|
• Free chlorine solution less than 20 ppm |
• Free chlorine solution greater than 20 ppm • Clidox S |
3) Storing Clean, Sterilized Valves
In an appropriate container
Use storage recommendations from cage manufacturer.
Please see full disclaimers and recommendations in our Sanitizing, Sterilizing and Storage of Rack Manifolds, Drinking Valves and Recoil Hose operational guide – OP-000041 or contact an Avidity Science representative for more information.
Valve Care Guidelines:
Affixed-To-Manifold
1) Sanitization
Included are instructions for sanitizing the valves in a tunnel washer or ultrasonic cleaner. Follow the appropriate instructions based on the cleaning equipment used by the facility. See Avidity Science guide OP-000041 for full details of this process or contact an Avidity Science representative for more information.
Clean the manifold/integral valves according to the facility’s standard operating procedures for rack cleaning.
EQUIPMENT DAMAGE: All manifold drain and vent valves must be opened before cleaning. In the event water is retained in a manifold, and the drain and vent valves are closed during the cleaning and/or autoclaving procedures, steam can be generated which creates pressure that may damage the manifold and/or drinking valve components.
2) Sterilization
Do not use a vacuum cycle deeper than -15 in. Hg when autoclaving drinking valves to prevent deforming of o-rings and diaphragms.
EQUIPMENT DAMAGE: All manifold drain and vent valves must be opened before autoclaving. In the event water is retained in a manifold, and the drain and vent valves are closed during the cleaning and/or autoclaving procedures, steam can be generated which creates pressure that may damage the manifold and/or drinking valve components.
IMPORTANT: Consult the rack manufacturer's autoclaving specific cations to determine that all rack components can be autoclaved at the cycles specified below. Do not autoclave any rack components that cannot tolerate these autoclave cycles.
Sterilizing While In Service
Sterilize the outside surface of the valves on the manifold following the manufacturer’s instructions
- Cold sterilant (see next page for approved cold sterilants)
- Sterilize using a water solution containing a free chlorine concentration no greater than 20 ppm.
- For applications where valves are continuously exposed to free chlorine, use a free chlorine concentration no greater than 10 ppm.
Cleaning of the Valve:
- Apply the cold sterilant as directed.
- Follow up the sanitization with a clean water rinse to remove ant residual cold sterilant.
EQUIPMENT DAMAGE: The free chlorination level in the cleaning or sanitizing solution cannot exceed 20 ppm for valve exposure greater than 45 minutes. Exposure longer than 45 minutes to a solution with a free chlorine concentration greater than 20 ppm can damage the drinking valves.
EQUIPMENT DAMAGE: For continuous free chlorine use, do not expose manifold and valves to a free chlorine concentration greater than 10 ppm. Continuous exposure to a water solution with a free chlorine concentration greater than 10 ppm can damage the manifold and drinking valves.
Removing Valves From Service
Do not use a vacuum cycle deeper than -15 in. Hg when autoclaving drinking valves to prevent damaging of shields, o-rings and diaphragms. After the valves are sterilized, place the valves in the autoclave the same way they were placed in the cage washer.
Drinking valves can be removed from service and sterilized using an autoclave. Autoclaving procedures will vary depending on facility protocols and autoclaving equipment. Follow the autoclave manufacture instructions and heed the cautions they state. General autoclaving cycle recommendation for valves are below.
- Do not use a vacuum cycle deeper than -15 in Hg
- Do not exceed a sterilization temperature of 149˚C (300˚F).
- Dry cycle vacuum pull no greater than -15 in Hg
