The safest, most reliable method of water delivery is automated.
An Edstrom Automated Watering System is the safest, most reliable method for providing high-quality drinking water to all your research animals. Each product is specifically designed and rigorously tested to ensure animal safety. The foundation of every Edstrom watering system is absolute dependability. Edstrom is a leader in the industry with drinking valve innovations that ensure animals and cages stay dry. Our proven shielded drinking valve is used to water millions of mice and rats in ventilated cages. These valves have an exceptional record of reliability and are easy for animals to use.
The unique, patented design of the Edstrom drinking valve utilizes precision-manufactured parts including a guard to protect the stem from accidental movements, a shield to help prevent bedding from entering the valve, and an O-ring and diaphragm to provide the sealing force to deliver water on demand. Every Edstrom drinking valve is manufactured and tested under strict quality control at our facility in Waterford, Wisconsin.
Highest Quality Materials. We use only the highest quality materials, such as 316 stainless steel and silicone that withstand the rigors of sanitization and water treatment. Our valves are precisely manufactured, calibrated, and individually tested.
Drinking Valves to Suit Your Species
Edstrom has drinking devices for almost every animal in the vivarium. Whether you have mice, rats, dogs, guinea pigs, primates, hogs, birds, cats, rabbits, etc., we have drinking valves to suit the species. Animals simply bite, lick, or nose the stem of the valve and water flows out at a controlled rate appropriate for the species. When the animals release the stem, water flow immediately stops.
In the normal, closed position, the head of the stem is held securely against the O-ring by the elastic diaphragm, preventing water from flowing under the stem head and out the valve.
When the end of the stem is moved in any direction by biting, licking or pecking, the head of the stem pivots on the O-ring. One side of the head lifts off the O-ring and allows water to flow under it and out to the animal's mouth or beak.
When the animal releases the end of the stem, the elasticity of the silicone rubber diaphragm located behind the stem head pushes the head back to the closed position, stopping the flow of water.
The many advantages and benefits of this simple valve design.
Local plumbing codes may require that you install an Auto-Air Break Valve at the point you connect your automated watering system to your domestic water supply. Use an approved device for this purpose.
