Yes it is.
The helicon was the predecessor of the sousaphone. It was a large, circular-shaped brass instrument with the bell facing forward, designed for marching bands. The sousaphone was developed to improve the portability and projection of sound while marching.
There is no such thing as "high brass". Only brass and low brass, and sousaphone/tuba is classified as low brass.

The tuba is the largest brass instrument with the largest mouthpiece. In marching the Sousaphone and the Contrabass bugle (known as contra) are marching versions of the tuba. The contra is the lowest-pitched, largest, and heaviest marching instrument.

The sousaphone is a brass instrument that is a specialized type of tuba designed to be easier to carry and play while marching. It is played by blowing air through a mouthpiece, which creates vibrations in the instrument's tubing to produce sound. The sound is then amplified and projected out of the large, flared bell at the end of the instrument.
Brass
The sousaphone
The sousaphone is commonly associated with brass bands, marching bands, and concert bands. It serves as a bass instrument, providing a deep, resonant foundation for the ensemble's sound. Its design allows for easy playing while marching, making it ideal for outdoor performances and parades. Overall, the sousaphone contributes significantly to the richness and depth of brass and wind ensembles.
assuming you meant to write "valves", the brass instruments with valves include: -euphonium -Tuba -baritone -french horn -trumpet -mellophone -sousaphone -cornet among a few others
The sousaphone
The sousaphone is a brass instrument and a type of tuba that is designed to be easier to carry and play than a traditional tuba. It produces sound by the vibration of the player's lips into the mouthpiece, which creates sound waves that resonate through the instrument's tubing, ultimately amplifying the sound. The bell of the sousaphone is facing forward and upwards, allowing the sound to project outwards and upwards, making it ideal for marching bands.
