Product catalog summary

Overview: This document provides detailed information on Emerson Climate Technologies' solenoid valves and coils, specifically the 540RA series. It includes ordering information, specifications, features, and dimensional data.

Ordering Information: The document lists various solenoid valves with their respective Product Control Numbers (PCN), descriptions, connection sizes, and nominal liquid capacities for different refrigerants such as R-12, R-134a, R-22, R-407C, R-404A/R-507, and R-502. The capacities are provided in tons and kilowatts.

Features: Key features of the 540RA solenoid valves include the ability to be brazed into the line without disassembly, a PTFE diaphragm, extended ends for easy installation, long-life molded coils, and a low-pressure differential required for full opening.

Specifications: The maximum fluid temperature is 250°F, with a maximum working pressure of 500 psig and a Maximum Operating Pressure Differential (MOPD) of 250 psig. The valves are UL/CUL certified under file number MP604. It is noted that the mounting enclosing tube should not be more than 90 degrees off the vertical up position.

Valve Nomenclature: The document explains the nomenclature used for the valves, detailing the series, design, port size, connection type, and size. Valves are shipped without solenoid coils, which are available separately.

Valve Kits and Repair: Information on valve repair kits and gasket kits is provided, including part numbers and descriptions. A spanner wrench is included in the complete valve kit for service purposes.

Dimensional Data: The document provides detailed dimensional data for various valve models, including port size, connection size, and specific measurements (A, B, C, D) necessary for installation and maintenance.

Solenoid Valves & Coils The 540RA is a 2-way, normally open diaphragm valve. 540RA valves are used for liquid, suction and hot gas service. Can be brazed into the line without disassembly PTFE diaphragm Extended ends for easy installation Long-life molded coils Low pressure differential required for full opening Maximum fluid temperature: Maximum working pressure: MOPD: UL/CUL file number: NOTE: Mounting enclosing tube more than 90o off vertical up position is not recommended. NOTE: This valve requires a DM, MM or ASC2-Type coil assembly. ASC2-Type Coil requires snap cap and cable assembly (PCN:059261). Valve Series Design Series Connection Type T = copper entended ends * NOTE: Valves are shipped without the solenoid coils (VLC = Valve Less Coil). See coil assemblies for availability.
