120-240V Actuator 45IN#

The B321 is a three way stop valve used for mixing hot and cold water lines in residential and light commercial applications. 120-240V Actuator

The BELIMO LRB-120 Series actuator uses a magnet-operated 3-way solenoid valve and incorporates a floating ball for switching. The silver alloy body is bonded to the core by anodic coating and the internal parts are made from the best material, featuring high efficiency and long wearing life. Features include:

This actuator is a totally enclosed pneumatic operator that provides precise motion control of vaned Damper using the B3 valve body (Sold Separately)

The Surface Mounted 3-Way, 24VDC Air Vent Actuator is a single-use, surface mounted air vent actuator. The LRB120-3 and B321B+LRB24-3 are approved for Duct Load Control applications; the LRB120-3 is not UL approved when used in duct load control applications. The CCV model comes with a sensing line only (no spring) to be used with a contactor controllers that provide CCV signals. The 0.75" diameter mounting plate is required when using this product and must be ordered separately.

The LRB120-3ACN is a 3 way, 3 position, variable speed control, AC PWM Non-Spring actuator for use with the Belimo B321B and B321C General Duty Valves, and the B21C and B21D Steam valves.

The 3-Way valve combines the functions of a mixing and diverting valve into a compact body. It is particularly suited for use in heating/cooling systems with small flow rates. The valve includes internal overload protection and an integral actuator that uses standard size Line Regulating Elements (LREs). The mixing and diverting function is achieved through the positioning of the LRE inside a linear operating range of the actuator. The LRE provides substantially more control over the flow than conventional rotary regulators.

The  LRB120-3  is a  3 way  non-spring return position valve switch with an adjustable travel stop. The valve has a mounting flange and is designed for use on standard B321 type control valves. The actuator has three, 120 volts AC coils and a separate 24 volt Auxiliary supply. The auxiliary supply is intended to be used by GSK10 (w/b) to derive its 12V DC coil power from the 100-240 VAC field power.
