24VAC/DC PROP. NSR

The TR24-SR is a 24VAC/DC 2-way, non-rising stem type proportional control valve for 3/8" to 2" copper or stainless steel tubing. The TR24-SR is an audible device in a class of its own. It can be used to control water, air and steam applications.

The BNFS series are normally closed, 2-way solenoid valve units with built-in electrical actuator for remote control. The dedicated solenoid coils allow the valves to be wired in a parallel circuit to provide 0.5" open and 7.4 Cv flow capacity while only requiring +24 VDC or 110/220VAC as power source. Flow is preset at the factory and is not user adjustable except by changing the PROPORTIONAL controller range.

The TR24 is a two-way valve especially designed for use in buildings where low differential pressures are present. The PROPORTIONAL, NON-SPITTING characteristic of this valve is due to its internal design. The proportional characteristic is referred to as 'Auxiliary Flow' and it relies on the TR24 diaphragm ability to control short surges of pressure without activation of the 24V solenoid valve.

The Belimo TR24-SR | B214B+/500 US | CCV | 0.5" | 2 Way | 7.4 Cv | w/ Non-Spg is a proximity-type, normally closed, normally open kit valve with an adjustable 2 way or 3 way position control option available through our external parts program. The two rotatable positions allow the valve to be mounted in any orientation without affecting function. The 1/2" Temperature Limit and pressure relief versions are ideal for systems where freezing temperatures are possible.

The TR24-SR is a 2-way multi-vane proportional valve with an integral spool for smooth actuation and positive positioning. The unique combination of wirewound resistor and integral spool results in precise control in a compact body.

The TR24-SR, B214B+/500 is a 2-way reversing valve. The two-way reversing valve is an accessory for use with a proportional control valve.
