Frequently Asked Questions
What is the primary technical difference between the Milan manual valve and a thermostatic valve?
The Milan manual valve operates as a fixed aperture device meaning it does not automatically adjust the water flow based on room temperature. A thermostatic valve contains a wax sensor that expands to close the valve when the room gets warm whereas the Milan manual valve remains open at the specific position you set it to. This technical characteristic makes the Milan range superior for bathrooms or rooms containing a wall thermostat where constant flow is required to prevent boiler cycling issues.
How do I determine whether I need an Angled Straight or Corner Milan valve for my installation?
Selecting the correct valve body depends on your pipework orientation relative to the radiator inlets. You should choose the Angled pattern if your pipes come from the wall or floor and connect to the side of the radiator. You should choose the Straight pattern if your pipes run along the wall or floor and connect directly into the radiator underside without turning. The Corner pattern is the best problem solving solution for pipes coming from the wall that need to connect to the side of the radiator as it allows the valve head to point inwards rather than protruding into the room.
Can the Milan Manual Valve range be installed on standard UK 15mm copper pipework?
Yes the Milan range is manufactured with a standard 15mm compression inlet which is the universal standard for UK residential heating systems. The valve includes a nut and olive that creates a high pressure watertight seal directly onto 15mm copper or plastic barrier pipe. If your system uses microbore pipework such as 8mm or 10mm you will need to insert a specific reducer into the compression fitting to ensure the valve grips the smaller pipe securely without leaking.
Is the finish on the Milan valves durable enough for high humidity bathrooms?
The finishes on the Milan range including Chrome Anthracite and Black Nickel are applied using advanced plating or powder coating techniques designed to withstand humid environments. This makes them highly suitable for bathrooms and wet rooms where moisture levels are high. To maintain the finish simply wipe with a soft dry cloth; avoid abrasive chemical cleaners which can strip the protective coating and potentially invalidate the 10 year guarantee.
How do I balance my heating system using the Milan manual valve set?
The Milan set typically includes one wheelhead valve for daily operation and one lockshield valve for balancing. To balance the system you must adjust the lockshield valve (usually the one on the return pipe) using a specific tool or Allen key. By restricting the flow through this valve you increase the hydraulic resistance forcing more hot water to travel to radiators further away from the boiler. This technical procedure ensures that all radiators in the property heat up evenly.
What are the maximum pressure and temperature ratings for the Milan valve range?
The Milan valves are constructed from heavy duty brass capable of withstanding significant system stress. The maximum operating pressure is typically rated at 10 Bar which covers all domestic combi and system boilers. The maximum operating temperature is generally around 110 degrees Celsius. For optimal performance in high pressure systems ensure the differential pressure does not exceed 1 Bar to prevent water hammer or noise from the valve seat.
Can I use the Milan manual valves on a dual fuel heated towel rail?
Yes manual valves like the Milan range are the standard technical choice for dual fuel towel rails. Because dual fuel rails often use an electric element for summer heating a thermostatic valve can sometimes cause conflict or shut off prematurely due to the heat from the element. The Milan manual valve ensures the rail remains isolated or open as required allowing for safe and effective operation of both the central heating and electric functions.
Are the Milan valves compatible with designer radiators that have bottom center connections?
Yes the Milan range is fully compatible with designer radiators featuring standard 1/2 inch BSP connections. For radiators with "underside" connections centered at the bottom you would typically use the Straight valve pattern if your pipes come up from the floor. If your pipes come from the wall you might use Angled or Corner valves depending on the specific clearance and aesthetic preference ensuring the valve heads do not clash with the radiator panel.
What tools are required to install the Milan manual valve set without damaging the finish?
To install the Milan valves professionally you will need an adjustable spanner or a smooth jawed wrench. Using a standard serrated grip wrench can scratch the high quality chrome or painted finish. You will also need PTFE tape or a liquid thread sealant to ensure a watertight joint between the valve tail and the radiator. For the lockshield adjustment a small Allen key or flat head screwdriver is usually required to turn the internal spindle.
Why is the 10 Year Guarantee important for manual radiator valves?
The 10 Year Guarantee provided with the Milan range indicates a high confidence in the quality of the internal brass components and the sealing mechanisms. Radiator valves are subjected to constant thermal cycling (heating up and cooling down) which can cause inferior seals to perish and leak over time. A long warranty period assures you that the O-rings and valve seats are of a technical grade sufficient to withstand a decade of use without failure or seizing.
