Sealing element, particularly for shut-off and regulating valves, and

A plumbing fixture has a housing adapted to be secured to a support surface, forming a compartment dimensioned to snugly receive a battery, and formed with a passage extending from the compartment to the surface. Contacts exposed in the compartment are positioned to engage terminals of the battery. At least one feed conduit extends from the housing through a hole in the support surface so that liquid can be fed to the housing through the conduit. An electrically controlled valve in the housing is connected to the contacts and to the conduit for altering characteristics of fluid flow through the housing. A battery simulator is provided including a battery-replacement unit dimensioned like the battery, received in the compartment, and having terminals engaging the contacts. A flexible supply cable extends from the unit through the passage and surface and has an outer end outside the housing. A fitting on the outer end can fit with a standard line-voltage supply. Circuitry in the battery simulator converts alternating line-voltage current to low-voltage direct current and supplies the direct current to the terminals of the battery-replacement unit.
