The Hoshizaki 322110-01 crescent cuber drain valve spring helps maintain smooth operation in compatible ice machines. This spring is a small but essential mechanical component used within the drain valve assembly to provide the tension needed for the valve to open and close correctly during drain and harvest cycles. It works by applying consistent pressure to return the valve to its proper position after water is released, helping regulate water flow within the system. By supporting accurate valve movement, it helps prevent drainage issues, reduces the risk of water buildup, and contributes to reliable ice production and efficient day-to-day machine performance.
