For each type of solenoid valve, you will also need to consider appropriate sizing and power requirements. This can be achieved by calculating a match between your precise usage needs or working conditions and the valve’s rated performance specifications in various areas. To this end, manufacturer guidelines should always be observed across each of the following areas.

In response to an electrical input signal, the open/closed state of these two ports is reversed, allowing for various valve operations to be controlled. Flow can thus be diverted between channels as required, in accordance with the way the port connections have been set up and connected within the larger pipeline system.

In a standard ‘spool’ or ‘poppet’-type solenoid valve, the valve itself is connected directly to a plunger, pivoted armature or another similar device, which for most models will be spring-mounted in some configuration. This plunger is located inside a hollow tube, often referred to as the solenoid ‘core’.

Hydronic floor heatingpros and cons

Solenoid valves are incredibly useful to engineers and end-users due to their automatic operation. The requirement for an engineer to be physically present to operate a valve manually is removed with the use of solenoids asthey can be installed and used anywhere that gas or fluid flow needs to be automatically controlled and monitored.

You will also need to potentially consider some of the solutions for solenoid valve adapters and mounts. Broadly speaking, these will often align with the type of pipeline where they will be installed, for example:

Many different types of solenoid valves are currently available. This is an inherent benefit of the component's great versatility - the wide range of solenoid types and functions means that it is usually possible to choose a valve that will precisely suit the role it is needed to perform and the application and environment where it will be installed.

Hydronic radiant floor heatingkits

When it comes to creating a cozy and energy-efficient home, underfloor heating is a popular choice. It provides an even distribution of heat and can be more comfortable than reverse air and gas heating. Two primary types of underfloor heating systems are electric and hydronic. Each has its distinct advantages and considerations, and understanding these can help you make an informed decision based on your specific needs and circumstances.

With pilot operated solenoid valves, the opening or closing of the valve is powered by the energy stored in the build-up of pressurised fluid or gas.

Hydronic radiator panel and ceiling heating relies on natural convection and radiation to heat your home in silence and comfort, without the dust and allergens often associated with ducted central heating. A luxurious heating method, hydronic heating also offers superior design and a range of styles to complement any modern or traditional setting.

When electrically energised, the wire coil wound around the outside of this core creates a magnetic field inside the tube. In turn, this influences the motion of the plunger, which then pushes or pulls the valve in a particular direction, with the end result being the opening or closing of the flow system. The precise way in which the solenoid functions - either to open or to close a valve when automatically activated - will depend on the specific type and configuration of valve and solenoid controller chosen, and thus its ‘normal’ operating state.

Some types and models of solenoid valve controllers employ additional components, including advanced circuit technologies, to offer more complex or responsive functions and features. For example, these might include the ability to manage proportional flow or pressure control, achieved through coil sensitivity to a broader range of input signal strengths.

With direct operated solenoid valves, the energised solenoid acts directly on the valve sealing piston or armature. Therefore, the ability of the valve to restrict or enable flow depends on the rated power - in other words, the physical strength - of the component.

Hot waterradiant floor heatingsystems

Hydronic underfloor heating relies on pipes laid in the concrete slab or screed to carry heated water. The water can then be heated by various energy sources including gas boiler, electric heat pumps and solar hot water systems. Hydronic heating installations are invisible (with no vents or ducts on floors or walls) and silent in rooms as radiant heat rises from the floor surfaces of your home, heating it from the ground up.

The vast majority of modern solenoid valves are manufactured from robust and relatively corrosion-resistant materials. Depending on the intended usage, some common solenoid valve materials might include:

Three-way or three-port solenoid valves have three input/output ports and two valve seals, one of which will always be open and one of which will always be closed in normal (inactive) mode.

Throughout this comprehensive guide, we will take a close look at how solenoids work, get to know some of the various types of solenoid valves currently available, and explore what types of applications and environments they are most commonly used in.

Regular service & maintenance of your hydronic heating system will ensure your system is running at peak performance and will add longevity to its lifespan.

When installing electric underfloor heating, one critical consideration is whether or not to insulate the floor. While it might seem like an additional expense, insulating the floor can significantly enhance the efficiency and effectiveness of your heating system. Here are four compelling reasons why floor insulation is essential when installing electric underfloor heating:

For gas solenoid valves, where gases are considered a compressible media, there are a couple of slightly more complex considerations to take into account as well. These might include gas temperatures at various stages of the pipeline, shifting flow rates expressed in cubic feet per hour, and resulting absolute pressures at both the inlet and outlet ports.

When choosing a solenoid valve to install in a particular pipeline or flow system, the key requirements to consider will include:

Two-way or two-port solenoid valves are among the most common types available. In essence, they simply control one inlet port and one outlet port, and work to open or close the valve whenever they receive an electrical activation signal.

It’s worth noting that, in fluid dynamics terms, ‘normally open’ (i.e. flow-enabled) valves typically imply the opposite meaning to ‘normally open’ gates in electronics systems.

Hallmarks of Amuheat floor heating products include affordable luxury comfort, energy efficient use, and control by smart programmable thermostats. And as heat naturally rises, no heat is wasted with Amuheat whose underfloor heating systems are gentle and low temperature, with no air movement, dust, noise or dry air.

Other components you might find in more advanced systems could include various arrangements of DIN terminals and connectors, for example, providing numerous options for subsequent output signals and onward controls to influence a range of behaviours further along in the system.

Electric floor heating is a simple and cost-effective way of heating select rooms or entire homes alike. Amuheat electric heating systems are available to be installed under most floor coverings including under carpet, tile and floating timber floors.

Your hydronic gas boiler or electric heat pump is the central component of your hydronic heating system, and it is recommended the system be serviced every 2 years. * Note some system brands require system services annually to maintain the system warranty.

Pilot operated solenoids can be internally or externally piloted. Internally piloted solenoid valves are used for higher pressure systems, usually found in larger pipeline setups where pressure differentials do the bulk of the work to open or close the valve. Externally piloted solenoids rely on a third-party component, such as a spring or armature, to push or pull the valve/diaphragm, working in conjunction with the typically lower pressure differentials commonly encountered in smaller pipelines.

We make choosing the correct floor heating system simple with a complete service offering which includes direct sales, support, specification,design and project installation teams for professional installation support.

Manufacturer guidelines for each of the above criteria tend to list the maximum safe rating in each case. As a result, you will need to ensure that your operating parameters fall below the specified ratings in all cases.

In terms of basic media compatibility and operating fundamentals, the options in the list below are all common variants. Many types of solenoid valve will offer specific functionality in one or more of the following areas:

Systems that stop working, generally is a result of an electrical surge that damages the safety switch or wall thermostat controller. And where there is damage to the embedded heating cable as result of same, or if there is damage that has gone undetected during the flooring installation that now presents after the heating is turned on and running, there is assistance available to trace the heating cable, locate the damage spot and repair with minimal floor rectification work required to make good.

A solenoid valve is often constructed in either poppet or spool format as a basic model option, although more specialised versions are available for tackling specific or demanding workloads, media, functions and environments. Most solenoids are modularly constructed around a fundamental arrangement of a few key components, namely:

A solenoid valve is an electromechanically operated valve component that is used to control the rate of flow in fluid or air-powered mechanical systems. They are used in many applications for the fluid control of water, air, oil or gas.

Solenoid valves are essentially flow control units with the ability to either restrict or enable flow, depending on the type of valve in question and whether or not they are in a currently activated (energised) state at any given time. But exactly how does a solenoid valve work in practice?
