Belimo G225S-L+LF24-SR Us 2-way Globe Valve 1 in 14 Cv 24V

Product Description

The BELIMO G225S-L+LF24-SR US is a factory-assembled 2-way globe valve and electric actuator combination designed for modulating control of hydronic heating and cooling systems. The valve features a 1 inch female NPT threaded connection, a flow coefficient (Cv) of 14, and stainless steel trim rated to ANSI Class 250. The spring-return electric actuator operates on 24 volts AC and accepts a 2-10 VDC modulating control signal, delivering 35 inch-pounds of torque. The assembly ships with 3 feet of 18 GA appliance cable terminated with a 1/2 inch NPT conduit connection. Licensed HVAC mechanics and controls technicians are the primary installers of this assembly.

This valve and actuator assembly is suited for commercial and light industrial HVAC applications where modulating zone control is required. Modified equal percentage flow characterization makes it well matched to coil-based heating and cooling equipment where proportional valve response improves system efficiency and comfort. The female NPT threaded end connection simplifies installation into standard pipe runs. Spring return functionality ensures the valve moves to its fail-safe position on loss of power, which is a common design requirement in occupied building systems.

Key Features

• 2-way globe valve with modified equal percentage flow characteristic for stable coil control
• ANSI Class 250 pressure rating with stainless steel trim for durability in hydronic service
• Spring-return actuator provides fail-safe positioning on power loss
• Modulating control via 2-10 VDC signal for precise flow regulation
• 24 VAC actuator supply voltage compatible with standard HVAC control systems
• Includes 3 feet of 18 GA appliance cable with 1/2 inch NPT conduit connection for field wiring

Compatibility

Designed as an OEM-style replacement or new-installation valve and actuator assembly for modulating hydronic control applications using 1 inch female NPT pipe connections and 24 VAC control systems.

Installation Notes

Installation should be performed by a licensed HVAC technician or controls specialist. De-energize the control circuit and isolate the piping section before servicing or replacing the assembly. Verify that the control system output signal matches the 2-10 VDC input range before applying power to the actuator. Follow applicable local mechanical and electrical codes, including NEC requirements for low-voltage control wiring, and confirm pipe system pressure does not exceed the valve pressure class rating.
