Animal drinking valve

An animal drinking valve configured to penetrate a penetrable container to allow a liquid to flow from the penetrable container through the valve, the valve comprising:

• a piercing member configured to facilitate penetration of the penetrable container by the valve;
• and
• a base member operatively coupled with the piercing member, the base member comprising:
• a flange portion;
• at least one exterior channel feature;
• and
• at least one sealing member at least partially disposed within the at least one exterior channel feature;
• wherein in operative interfacing of the valve with an installation site through which the liquid is to flow:
• the penetrable container resides proximate a first side of the flange portion;
• an opening formed in the installation site resides proximate a second side of the flange portion, said second side opposing said first side;
• and
• the at least one sealing member provides a liquid-tight seal at the installation site such that the liquid does not otherwise flow through the installation site in bypass of the valve.
