Continuous brass manifolds used for controlling water flow in Hydronic floor heating systems. The supply side manifold comes with or without flowmeters. The return side manifold is equipped with integrated Danfoss pre- setting  valves  for  easy  balancing.

With hydronic floor heating systems water is heated in a boiler and circulated at safe low pressure at around 35 – 40C through extremely durable plastic pipes laid in or under the floor.

Flow control valves are most commonly used to slow-fill pipelines to prevent water hammer, especially at center pivot points on large pipe networks. They can also be used to limit the flow rate of a valve discharging into a pond, canal, or reservoir.

For floor heating, the heat source is connected to one or more manifolds, with one manifold per floor level for a typical house. Each manifold can have a number of floor heating circuits.

Alternatively, radiator panels can be used in cases where floor heating is not an option. Although they are called ‘radiators’, they provide predominantly convective heat with some radiant heat. In general, radiant systems like floor heating are more efficient, particularly with higher ceilings, and they provide more comfort for the occupants.

The FJVR valve (normal flow) is used exclusively in conjunction with the FJVR return temperature limiter sensor. The FJVR valve is mounted in the outlet of a radiator or floor heating circuit. The valve and sensor can be fitted in any position as long as the flow direction is observed.

The Diffusion Plate System accommodates 16mm heating pipes and uses 0.8mm thick aluminium plates to diffuse the heat over the floor area. The heat is then transferred through the floor surface into the room. Due to the high conductivity of the  plates  the reaction  time  compared  to  traditional  screed  systems  is  reduced.

The thermal actuator TWA range is used with electrical on/off-controls to activate several types of valves and floor heating manifolds. The actuator is equipped with a visual position indicator to show the open or closed position of the valve. The TWA-actuator can be connected to the RA, RAVL and RAV valves from Danfoss. Furthermore versions for valves with M30x1.5 connection are available. The actuator is made for either 24 V (SELV) or 230 V supply in both normally closed (NC) or normally open (NO) versions (valve positions with no supply voltage to the actuator). The 24 V actuator for RA valves also comes in a NC/S-version having an end-switch.

This system has been designed for timber joist floors or battened timber floors over concrete slab applications with hydronic floor heating systems. Insulation is required under a suspended timber floor application and is recommended when installed over a concrete floor.

In hydronic floor heating systems water is heated in a boiler and circulated at safe low pressure at around 35 – 40C through extremely durable plastic pipes laid in or under the floor.

The Danfoss floor heating manifolds are used for heat regulation in floor heating systems. Both flow and return manifold have 1” connections, with connections for between 2 to 12 heating circuits. The manifold is equipped with Danfoss’ integrated valves with pre-setting for easy installation and commissioning. The valves are controlled by Danfoss’ TWA thermal actuators. A full programme of manifold accessories, including brackets, end sections with drain taps and automatic air vents, ball valves, thermometer and reduction pieces, is available.

A Nelson Rate-of-Flow pilot uses a velocity-sensing paddle to limit the system flow rate. The paddle and pilot are installed in the pipe upstream of the valve. For slow-fill applications, the pilot should be set to 110-120% of the design flow. When the valve is first opened, the pilot throttles the valve to prevent high flow water hammer. When the pipeline is full and the design flow is reached, the pilot allows the valve to go fully open, or respond to other controls (such as a pressure reducing pilot).

The pre-fabricated floor heating mixing shunts are used for regulating the correct flow and supply temperature into the hydronic floor heating system. Compact mixing shunts for regulating flow and supply temperatures in floor heating systems. Their compact and flexible design allows the shunt to be mounted on either side of the manifold. A self-acting proportional regulator is used to regulate the supply temperature to ensure it is always constant and at the required temperature.
