The Belimo B311+TR24-3 | -T has a flow rate of 1.85 Cv (1.9 l/m) and is 3-way valve. This component can only be used on floating heat/cooling application...

Sometimes an end-user will purchase a control valve close to the full configuration but with one or more additional features. In this situation, it can be hard to find an existing description for the end use. In an instance like this, a best fit description of the features needed and how they work may be used. For example below is an excerpt from a product description that uses best fit to describe a float valve:

The B-311 series 3/2 way valve offers a wide variety of control options. This 3/2 way valve is used as an ON-OFF or as an ON-ON valve and can be installed vertically or horizontally with the appropriate mounting bracket. Due to its anti corrosive properties it is ideally suited for use in swimming pools, recirculation systems, spa and steam room installations and many other sensitive applications requiring hydrodynamically balanced operation. The stainless steel ball assembly and the open design of the flow path prevent blocking and extend valve life.

The B311+TR24-3 | -T US is a 24 VAC, non-spring return, 3-way solenoid valve. This valve can be used as an on/off or flow control valve with 24 VAC voltage applied to the coil. It provides full range flow control from 0% to 100%. Typical applications include irrigation sprinkler systems, and HVAC throttling controls.

The 3-way valve features a separate on/off switch and a proportional knob for adjusting the flow of water to 1 or 2 valves. The Belimopress® is a fully adjustable non-spring pilot operated pressure control with red, chrome plated steel knobs. The 24VAC (2A) solenoid is actuated by a normally open contact and has a lock out feature that prevents turning on the heat if there is no communication or the wiring fails.

Composed of B311 top body, TR24-3 bottom body, and corresponding fittings. The B311 is a two way, three position controller with built in sensors (B311 only works as a 3-way when used with the TR24-3 bottom body). The controller makes use of a new Wiring Junction Box (WJB) which eliminates the miswiring problems encountered with field wiring.
