Manitowoc 10551 Automatic Expansion Valve

Product Description

The MANITOWOC 10551 is an automatic expansion valve (AEV) designed for use in commercial ice machine refrigeration systems. This valve maintains a constant evaporator pressure by automatically modulating refrigerant flow in response to downstream pressure changes, ensuring stable low-side conditions during the freeze cycle. It is a factory-replacement part sourced from Manitowoc Ice and is typically installed by a licensed refrigeration or HVAC technician during a system repair or refrigerant-side service call.

This valve is intended for Manitowoc Ice commercial ice-making equipment. Automatic expansion valves of this type are commonly found in medium-temperature refrigeration circuits where consistent evaporator pressure is required for repeatable ice production. The 10551 is cataloged under Manitowoc Ice parts and accessories and is suited for commercial appliance service environments.

Key Features

• Automatic pressure-regulating design maintains constant evaporator pressure during ice machine operation
• OEM replacement part designed to factory specifications for Manitowoc Ice commercial equipment
• Controls refrigerant flow to the evaporator without electronic input, reducing points of failure
• Suitable for commercial-grade refrigeration service demands

Compatibility

Designed as an OEM-style replacement automatic expansion valve for Manitowoc Ice commercial ice machine refrigeration systems.

Installation Notes

Installation should be performed by a licensed refrigeration technician holding an EPA Section 608 certification, as this work involves a sealed refrigerant system. The system must be fully recovered and depressurized before removing the existing valve. Verify the correct inlet and outlet orientation before brazing or connecting fittings, and pressure-test the system after installation prior to recharging with refrigerant.
