Finally a valve that can stand up to the abuse large birds dish out! The parrot valve is made from heavy duty stainless steel. Parrots love it! 1/2" male pipe thread for use in rigid piping systems. (For use with #1630-2912-001, Fitting PVC Adapter Tee).
How it Works: To drink, birds simply move the stainless steel stem by biting or licking, releasing water. When the bird 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.
