Emerson Alco 027769 Valve

The Emerson Alco 027769 expansion valve, specifically the 9761-5 model, is a high-performance heat pump expansion valve designed for TCL and TCLE valve body configurations. This component features straight-thru body flow with 3/8" ODF sweat inlet and 1/2" ODF sweat outlet connections, ensuring a precision fit in tight evaporator or condenser coils. Engineered for refrigerant flow control in residential and light commercial systems, it manages superheat adjustment effectively across varying load conditions. The ODF connection design facilitates a secure, leak-proof brazed joint, essential for maintaining system vacuum and charge integrity. As a critical HVACR replacement part, the 027769 ensures optimal liquid refrigerant metering, preventing liquid slugging and protecting the compressor. Technicians favor this Alco thermostatic expansion valve for its field-proven durability in high-cycle R-410A or R-22 applications, providing reliable evaporator coil efficiency and system pressure stability under extreme ambient temperatures.

• Straight-Thru Configuration: Simplifies piping layout and reduces pressure drop in tight HVAC mechanical rooms.
• Interchangeable Power Assemblies: Compatible with TCL/TCLE series power heads for flexible field superheat setting.
• Durable Brazed Connections: The 3/8 x 1/2 ODF sweat ports allow for standard HVAC brazing techniques without the need for additional adapters.
• Optimized Metering: Specifically designed to handle the bypass requirements found in modern heat pump systems.

What is the primary application for the 9761-5 valve body?
This body is designed for use with Emerson TCLE and TCL series thermostatic expansion valves, typically found in air conditioning and heat pump units requiring straight-thru refrigerant flow.

Does this valve body include the internal orifice or power head?
This is the valve body only. The power head and cage assembly must be selected based on the specific tonnage and refrigerant type of the system being serviced.

Can this be used in bi-flow applications?
While the TCL/TCLE series is often used in heat pumps, the internal check valve functionality depends on the specific valve cage installed within this 027769 body.
