Yes they do, but they are actually called water keys or spit valves. Water keys allow you to empty liquid that builds up in the instrument that is formed by a combination of condensation and saliva.
The valves on the Euphonium or any brass instrument are used to change the length of tubing, allowing the player to reach various notes. Each valve pressed diverts the air stream through additional tubing, causing the pitch to change. Most Euphoniums have 4 valves but some have only 3, and nearly all current models are piston valved.

A 2-valved trumpet is actually a type of bugle. The purpose is the same as that on a normal trumpet. The only difference is that you can play fewer notes on the two valved instrument, but more than on a traditional bugle.
A euphonium is a low brass instrument. It can be base clef or treble clef. It looks like a small tuba but plays higher notes than the tuba. Most euphoniums have either 3 or 4 valves. See the related link below for a picture and more information on the euphonium.
Compensating euphoniums are for professionals or euphonium players that are really dedicated to playing. This is because compensating euphoniums are much more expensive than non-compensating euphoniums. All compensating means is that the instrument has the further advantage of being able to play in the lower octaves using conventional fingerings. See related link for more information.

The plural of euphonium is euphoniums.
There are three main types of toilet valves available in the market: fill valves, flush valves, and flapper valves. Fill valves regulate the water level in the tank, flush valves release water to flush the toilet, and flapper valves control the flow of water from the tank to the bowl.

The different types of shower valves available in the market include pressure-balancing valves, thermostatic valves, and manual valves. Pressure-balancing valves regulate water temperature and pressure to prevent sudden changes. Thermostatic valves maintain a consistent water temperature. Manual valves allow users to manually adjust the water temperature and pressure.

Water flow to fixtures is controlled by valves, which can include gate valves, globe valves, ball valves, and check valves. These devices regulate the flow rate and pressure of water, allowing users to turn the water on or off as needed. Additionally, faucets and showerheads have built-in controls that manage water flow at the point of use. Proper installation and maintenance of these components are essential for efficient water management.
there are valves on bilge pumps so that if there are traces of oil in the bilge water, the valves will close so that the oily water will not be discharged overboard. The valves are required to be screw down non-return valved
All showers need valves. They can be for the water supply, balancing the water and control of the shower. Without the valves, your shower will leak, causing damage to the surrounding areas.
Euphoniums come in several types, primarily distinguished by their configuration and playing style. The most common types are the compensating euphonium, which has additional tubing to enhance tuning and tone quality, and the non-compensating euphonium, which is simpler and often lighter. There are also variations in valve systems, such as the 3-valve and 4-valve euphoniums, with the latter offering greater range and flexibility. Additionally, euphoniums can be found in different keys, typically B♭ or C, catering to various musical contexts.

The valves arent shutting off and must be replaced.
