Genuine OEM replacement cartridge

The Gerber 97-231 pressure-balance cartridge and control is a direct-fit replacement for the GH-301 shower valve. It restores original anti-scald protection and temperature stability in single-lever installations.

Ceramic disc with balancing spool

A ceramic disc cartridge paired with a pressure-balancing spool delivers instant shut-off if hot or cold supply fails. The adjustable temperature limit stop and volume control let the installer set safe maximums during commissioning.

Single-valve pressure-balance standard

The unit maintains water temperature within a narrow range by reacting to supply-pressure changes, but it cannot compensate for seasonal inlet-temperature shifts or provide thermostatic precision. Buyers needing exact degree control or multi-outlet coordination will require a different valve architecture.

Questions about this item

Does the 97-231 cartridge maintain a tight temperature range under pressure changes?

The pressure-balance design keeps outlet temperature within ±3 °F when supply pressure fluctuates.

What overall length must the valve body accept for this 5 3/4" cartridge?

The replacement unit measures 5 3/4 inches from tip to base, so the valve bore needs at least that depth.

Which way does the ceramic disc cartridge go in, and where does the temperature limit stop engage?

Insert the cartridge with the hot port aligned to the left supply, then rotate the limit-stop ring until the desired maximum temperature is reached before securing the handle.
