Rotalock Valve

Rotalock Valve - Service-Oriented Shut-Off Control for Refrigeration Systems

Product Features

• Rotalock Threaded Connection: Designed with standardized rotalock fittings to enable secure installation and removal without cutting or brazing the pipeline.
• Internal Shut-Off Mechanism: Allows isolation of compressors or system components during maintenance, reducing refrigerant loss and service downtime.
• Compatibility with Refrigerants: Suitable for use with common HFC and HFO refrigerants, including R134a, R404A, R410A, and R407C, depending on configuration.

Product Description

The Rotalock Valve is manufactured for use in commercial and industrial refrigeration and air conditioning systems where controlled isolation of refrigerant flow is required. The valve body is typically produced from forged or machined brass or steel to ensure dimensional stability under pressure and temperature variation. Precision-machined threads comply with industry rotalock connection standards, supporting consistent sealing performance when paired with compatible gaskets. The design supports system servicing, compressor replacement, and component inspection without full refrigerant evacuation, aligning with common HVAC maintenance practices.

Applications

This product is commonly used in the following scenarios:

• Compressor suction and discharge line isolation in refrigeration systems
• Commercial HVAC equipment requiring service-friendly valve connections
• Industrial refrigeration units where frequent maintenance access is required

FAQ

1. Can a Rotalock Valve be installed without welding or brazing?

Yes. The rotalock valve uses threaded rotalock connections, allowing installation and removal through mechanical fastening. This design is commonly used to simplify compressor replacement and reduce on-site hot work during maintenance.

2. How does a Rotalock Valve help reduce refrigerant loss during servicing?

The internal shut-off function enables technicians to isolate specific components, such as compressors, while keeping the rest of the system sealed. This approach minimizes refrigerant discharge, supports compliance with environmental regulations, and shortens service time.
