Resideo V2040ESL20 Valve

The Resideo V2040ESL20 is a professional-grade 3/4" NPT vertical angle radiator valve engineered for precision temperature control in one-pipe steam or hydronic heating systems. Designed for standard capacity requirements, this thermostatic radiator valve (TRV) body features a heavy-duty nickel-plated bronze construction, making it a reliable choice for contractors servicing free-standing radiators and convectors. With a 2.7 Cv capacity and a maximum steam pressure rating of 15 psi, the V2040ESL20 ensures optimal fluid dynamics and heat distribution. The integrated EPDM balancing cartridge provides a resilient, tight shut-off, mitigating common issues like overheating and system noise. For technicians working in tight mechanical spaces, the vertical angle pattern offers a streamlined installation footprint. This valve is normally open and requires the addition of a T100 series actuator for automatic, non-electric room temperature regulation. The cartridge is fully replaceable using the VA8200A001 service tool, allowing for efficient field maintenance without removing the entire valve body from the piping.

• Steam and Hydronic Compatibility: Rated for 15 psi steam and up to 150 psi in hot water applications.
• Standard Capacity Throughput: Features a 2.7 Cv rating, delivering up to 63,800 Btu/hr for consistent radiator performance.
• Field-Serviceable Design: The internal EPDM cartridge can be replaced using a specialized service tool, reducing long-term labor costs.
• Durable Construction: Nickel-plated bronze body resists corrosion and withstands temperatures up to 248°F.
• Compact Vertical Orientation: Specifically designed for limited-space installations where traditional horizontal valves may not fit.

What actuators are compatible with the V2040ESL20?
This valve body is designed to work with Resideo T100C, T100B, and T100F series thermostatic actuators, as well as MV100 electric controllers.

Does this valve require an external air vent?
Yes, for one-pipe steam applications, the valve assembly typically includes or requires a steam air vent to ensure proper radiator venting and heat cycle timing.

Can the cartridge be changed while the system is under pressure?
While the cartridge is replaceable, it is professional best practice to isolate the radiator or depressurize the system before servicing to ensure safety and prevent leaks.
