Brand: Emerson

Description

Overview

The ALCO Solenoid Valve 240RA9T9-T is a normally closed, direct-operated solenoid valve engineered by Emerson under the ALCO brand for refrigeration and HVAC systems. It is designed to deliver accurate, immediate flow control for refrigerant lines in commercial and industrial cooling equipment, giving technicians a dependable shut-off point wherever precise liquid or suction line control is required.

Seven Star LLC supplies the ALCO Solenoid Valve 240RA9T9-T and the wider ALCO/Emerson refrigeration valve range to HVACR contractors and industrial facilities across Oman and the GCC, with guidance on correct valve selection for the refrigerant and line size in use.

Operating Principle

As a direct-operated, normally closed valve, the 240RA9T9-T opens only when its coil is energized, using the solenoid’s magnetic force to lift the plunger directly off the seat rather than relying on a pilot pressure differential. This makes the valve responsive at low pressure differentials and suitable for systems where flow needs to start and stop cleanly on command from the control circuit.

The valve is rated for use with common refrigerants including R134a, R22, R404A, and R507, giving it flexibility across both legacy and modern refrigeration systems without requiring a different valve body for each refrigerant type.

Engineering Design of the 240RA9T9-T

The valve body features copper connections designed for brazing, producing strong, leak-proof joints during installation — an important detail on refrigerant circuits where even small leaks translate into lost charge and reduced system efficiency over time. Its construction resists corrosion and vibration, which matters in condensing units and compressor racks where the valve is mounted close to moving machinery.

The coil is field-replaceable and UL-approved, so a coil failure does not require replacing the entire valve body, and the body itself is compatible with ALCO’s broader range of accessories and connectors. The compact footprint allows it to fit into tight spaces within a refrigeration rack or condensing unit without compromising access for future maintenance.

Key Features

Industrial Applications

The 240RA9T9-T is used in walk-in freezers, cold storage warehouses, supermarket display cases, and commercial and industrial refrigeration systems where reliable liquid or suction line shut-off is required. Its tolerance for both low and high-temperature conditions makes it suitable for everything from retail cold rooms to larger industrial process cooling circuits.

Across Oman, Muscat, Sohar, Salalah, and the GCC, Seven Star LLC supports HVACR contractors and cold-chain operators as a trusted supplier of genuine ALCO/Emerson refrigeration valves, helping retrofit and new-build projects maintain reliable, leak-free flow control across their refrigeration circuits.

Why Choose Seven Star LLC for the ALCO 240RA9T9-T

Because the 240RA9T9-T is rated across several common refrigerants, R134a, R22, R404A, and R507, Seven Star LLC confirms which refrigerant your system actually runs before an order ships, since the valve body’s seal materials and pressure rating are validated for that specific list and substituting an incompatible refrigerant later without reverifying compatibility can shorten seal life even though the valve appears to operate normally at first. We also verify the copper connection sizing against your existing brazed line before shipment, since a mismatched connection size adds unplanned pipe-fitting work to what should be a straightforward valve swap.

For cold-chain operators running multiple walk-in freezers or display cases across several sites, we help plan coil and valve-body spares separately, taking advantage of the field-replaceable coil design so a coil failure does not require stocking a full replacement valve body for every unit in the fleet. Where a retrofit project is replacing older, no-longer-supported solenoid valves across a facility, we are glad to review the existing valve population and refrigerant mix before recommending a standardized ALCO replacement lineup.

Supporting Cold-Chain Reliability Across Oman and the GCC

A failed liquid-line solenoid valve on a commercial cold room or supermarket display case is not just an inconvenience, it puts genuinely perishable inventory at real risk within just a few hours, so response time on sourcing a replacement valve matters just as much as the valve’s own long-term reliability. Seven Star LLC keeps working relationships with Emerson/ALCO to support fast sourcing of the 240RA9T9-T and related valve models for cold-chain operators across Oman and the GCC, and we provide full datasheets and brazing guidance on request so contractors can complete the swap correctly on the first visit rather than requiring a costly and time-consuming return trip once an incompatibility is discovered partway through the installation.

About brand

Flow computers and remote controllers lead the Emerson listing here: the ROC800 series and the FloBoss 107 used for gas and liquid measurement at wellheads, metering skids and pipeline stations. Emerson, founded in 1890 and headquartered in St. Louis, USA, also stands behind Micro Motion Coriolis meters, Fisher FIELDVUE valve controllers and the DeltaV control system.

Seven Star LLC, an independent supplier, sources these Emerson products and their spare parts for users in Oman and the GCC.

Emerson product families on this page

The measurement and control group includes the ROC809 and the expandable ROC827 Remote Operations Controllers, the ROC800L for liquid measurement and the FloBoss 107 Flow Manager. Flow metering is represented by Micro Motion ELITE CMF Coriolis sensors and the 5700 transmitter. For valves there is the DVC6200 digital valve controller, plus solenoid valves and a safety relief valve. DeltaV hardware includes the PK Controller and DeltaV SIS components. Field tools are the AMS Trex Device Communicator and the earlier 475 Field Communicator, and wireless networks use the 1410S gateway with the 781S smart antenna. The cooling items are Copeland scroll and semi-hermetic compressors, which were sold for many years under the Emerson name.

Where Emerson equipment is used

ROC and FloBoss units calculate and log gas and liquid flow at production sites and custody transfer points. Micro Motion meters measure mass flow and density in loading, blending and fiscal metering. DVC6200 controllers position control valves and report valve diagnostics, and DeltaV runs process units in refineries, chemical plants and utilities. Copeland compressors serve air conditioning and refrigeration plants.
