Refrigeration Rotalock Angle Valves (ODF Solder)

Description

The Refrigeration Rotalock Angle Valves (ODF Solder) are essential isolation and service controls widely utilized across commercial refrigeration, air conditioning, and industrial cooling systems. Designed for direct mounting onto compressor spuds, liquid receiver vessels, and line tubing, these angle-pattern valves allow service technicians to isolate system components, recover refrigerant, or perform vacuum evacuation without disturbing fixed piping. Each valve features an optimized internal valve chamber to maintain maximum flow capacity while drastically reducing pressure drop across the circuit. Built to withstand demanding operating environments, the outer shell and threaded components feature protective tin coating or copper plating options alongside heavy-duty protective stem caps.

Technical Specifications

Key Features

• Convenient Service Isolation: Provides a quick, sealable shutoff point for servicing compressors and pressure vessels without discharging the entire refrigerant charge.

• Low Pressure-Drop Flow Path: Optimized angle body geometry ensures full liquid and gas throughput while minimizing internal friction loss.

• Heavy-Duty 48 Bar Rating: Precision-manufactured to safely withstand high pressure conditions found in modern HFC and HFO refrigeration systems.

• Corrosion Protection Finish: Tin coating or copper plating resists severe ambient atmospheric oxidation and moisture exposure.

• Integrated Gauge Access Port: Built-in side access port with protective sealing cap allows direct mounting of manifold hoses for diagnostics and charging.

• 100% Pressure & Leak Tested: Factory leak testing guarantees absolute sealing integrity prior to site installation.

Supported Applications

• Compressor Suction & Discharge Ports: Mounted on reciprocating, scroll, and semi-hermetic compressor service connections.

• Pressure Vessels & Receivers: Installed on liquid receivers, accumulators, and oil separators for system pump-down and isolation.

• Pipe Line Connections: Integrated into refrigeration rack suction and liquid line manifolds.

Benefits

• Facilitates fast, efficient field maintenance and component changeouts.

• Smooth ODF copper stubs allow clean, leak-free brazing into standard copper piping systems.

• Heavy-duty metal alloy Rotalock nut ensures tight gasket compression against compressor seating surfaces.

Package Includes

• 1 x Refrigeration Rotalock Angle Valve (Selected Size)

• 1 x Protective Stem Cap & Side Access Port Nut

Important Buyer Verification Notes

Notice for Technicians & Contractors: Match the internal ODF solder size and Rotalock thread dimensions with your compressor or liquid receiver mounting spud before ordering. Always install a fresh Teflon/PTFE Rotalock seal gasket during installation, and wrap the valve body with a wet cloth during line brazing to protect internal stem packing.

Frequently Asked Questions (FAQs)

What is the primary function of a Rotalock valve?

A Rotalock valve acts as a removable service isolation valve mounted on compressors or liquid receivers, allowing technicians to open, close, or isolate sections of the refrigeration system for maintenance.

What connection type do these valves use?

These valves feature standard ODF (female sweat) copper solder stubs on the line side and a swivel threaded Rotalock nut on the equipment mounting side.

What is the maximum working pressure for these valves?

These heavy-duty Rotalock valves are rated for operating pressures up to 48 bar (696 psig) and temperatures ranging from -40°C up to +150°C.
