Belimo G232S-M+LVKB24-SR Globe Valve with Electronic Fail-Safe Actuator - 1.25 2-Way

The Belimo G232S-M+LVKB24-SR is a complete valve and actuator assembly designed for precise proportional control of hot water, chilled water, or glycol solutions up to 60% in HVAC applications. This factory-assembled unit combines a stainless steel trim globe valve with an electronic fail-safe linear actuator for reliable, modulating control.

Valve Specifications:

• 1.25" (DN 32) 2-way globe valve with internal threads
• ANSI Class 250 construction, rated up to 400 psi below 150°F
• Flow coefficient (Cv) of 20 for precise flow control
• Stainless steel trim with modified equal percentage flow characteristic
• Suitable for chilled or hot water, up to 60% glycol, and steam applications

LVKB24-SR Actuator Features:

• Electronic fail-safe operation with 24 VAC/DC power supply
• Proportional control with 2-10 VDC input signal (4-20 mA compatible with optional resistor)
• 115 lbf (500 N) actuating force for positive valve control
• 90-second motor running time, less than 35 seconds fail-safe operation
• Low power consumption: 2.5W running, 1.5W holding
• NEMA 2/IP54 protection with UL Enclosure Type 2 rating
• 18 AWG plenum-rated cable with 3-foot length and 1/2" conduit connector
• Electronic overload protection throughout full stroke

This actuated valve assembly is ideal for controlling unit ventilators, air handling units, fan coil units, and other HVAC heating and cooling systems requiring accurate proportional control. The pre-assembled configuration ensures proper installation and eliminates field assembly errors.
