500RB

Product catalog summary

Overview: This document provides detailed technical specifications and ordering information for Emerson Climate Technologies' 500RB series solenoid valves and coils. These valves are used in refrigerant service for liquid, suction, or discharge gas applications.

Nomenclature: The valve model number (e.g., 500RB 4T3 VLC) indicates the valve series, design series, port size, connection type, connection size, and coil type. Valves are shipped without solenoid coils, which must be ordered separately.

Features: Key features include a universal coil fit for all valve sizes, extended ends for easy installation, remote positioning capability, long-life molded coils, low pressure differential for full opening, and superior external sealing with PTFE O-rings.

Specifications: The valves have a maximum fluid temperature of 250°F, a maximum working pressure of 500 psig, and a maximum operating pressure differential (MOPD) of 275 psig. They are UL/CUL certified under file number MP604.

Options: Connection types available include SAE, ODF, NPTF, and ODF inlet with ODM outlet. It is recommended not to mount the enclosing tube more than 90 degrees off the vertical up position. The valve requires a DM, MM, or ASC2-Type coil assembly, with the ASC2-Type requiring a specific cable assembly.

Ordering Information: The document includes a table listing various valve models, their connection sizes, and nominal liquid capacities for different refrigerants (R-12, R-134a, R-22, R-407C, R-404A/R-507, R-502) based on ARI standard 760-87.

Gasket and Coil Assembly: A gasket kit (KG10025) is available, containing PTFE and Neoprene O-rings. Only DM, MM, or ASC-Type style coils should be used, with MagMax style coils recommended for DC voltage operation.

Dimensional Data: The document provides detailed dimensional data for valves with and without extended ends, specifying port sizes, connection sizes, and styles.

Valve Kits: Complete valve kits are available for different valve sizes, with specific part numbers provided for ordering.
