AFR models are recommended for use in applications confined to heating or reversing horizontally mounted single phase centrifugal pump and air conditioning condensers. AFRB: 170in-lb S/R @ 2800rpm, B280+ package with factory installed foot return option and cast iron inlet/outlet D flange. Central control valve (CCV) with back pressure regulator (BP), 3" VSD full port, 180in-lb S/R @ 2800rpm, 1-1/2" NPT discharge with 1-1/4" slip x 2-1/4" slip x

The B280+ is a 2-way float valve designed to regulate 24v DC heat pump refrigeration systems with ambient air temperature control (AFTB). The B280+ features an auxiliary return, which allows for reduced pipe runs and simplified installation. In addition, the B280+ has a setpoint difference adjustment, allowing the user to adjust the temperature differential between the indoor and outdoor temperatures.

This is a full size photoelectric 2-way valve with 24v AFRB mounting option. It has an adjustable set point of 170Cv, and is approved for outdoor use.

The Belimo AFGB 24-S is a direct drive, 2-way, normally closed position regulating valve with fixed displacement and a spool outlet. The hydraulic power unit is 100% field adjustable without disassembly. This valve is hydraulically controlled and electrically supervised by either 24v dc or ac.

The AFRB24-S with Spg Rtn(spill return) is a 2 way, dual device control solenoid valve that modulates based on 0 - 5VDC and 24VDC signals. The B280+S is also B280+A just without the Spill return feature.

A 24V Power Head with a working pressure range of 170 to 280 psi and a static pressure rating of 20" wg. Drive Loop output ratings of 12V, 4.5A-6V, 3A---115V, 1A.  This power head can be used in applications where the air volume or mass flow rate should be adjusted depending on the room conditions such as controlled thermostatic damper opening via the power head.

The Belimo B280+ actuator is a proportional-integral-derivative type of actuator used for position control. The B280+ is compatible with 208 to 240 VAC or 24 VDC supply voltage and 3" Nominal diaphragm that is made of Nitrile Butadiene Rubber, 24 VDC motor, Output Rating: 3.60 to 4.4 amps at 24 VDC continuous rated load, 171 in
