Loge Square Manual Valve Range Radiators

The Loge valve features a cuboid, architectural shape which provides a specific technical advantage when installed on square-profile heated towel rails. Aesthetically, it continues the sharp lines of the radiator, creating a seamless visual integration that rounded valves cannot achieve. Mechanically, the square head offers superior grip leverage compared to smooth round handles, allowing the user to make fine adjustments to the flow manually, even if their hands are damp, which is a common scenario in bathroom environments where these valves are frequently installed.

You should choose the Loge Manual Valve for bathrooms because thermostatic valves (TRVs) often malfunction in small, humid rooms. The heat from a shower or bath can cause the air temperature to spike rapidly, tricking a TRV into shutting off the radiator while the room is still technically cold or the towels are damp. The Loge manual valve solves this problem by providing a fixed orifice flow that ensures the radiator remains hot constantly when the central heating system is active, guaranteeing dry towels and consistent heat output regardless of temporary humidity spikes.

Balancing is the process of equalizing hydraulic resistance across your central heating circuit. The Loge set includes one adjustable wheelhead and one lockshield valve. To balance your system, you must remove the square cap from the lockshield valve to access the internal spindle. With the wheelhead fully open, adjust the lockshield spindle using a spanner to restrict the water flow on the return pipe. By closing the lockshield on radiators closest to the boiler and opening it on those furthest away, you ensure hot water reaches every radiator simultaneously, solving the problem of cold spots in the house.

The Loge range is manufactured with a standard 15mm compression inlet, which is the industry standard for UK residential heating. It is not directly compatible with 10mm microbore pipes out of the box. To solve this, you must use a standard reducing set. This involves replacing the 15mm olive inside the valve nut with a specialized reducer that bridges the gap between the valve body and the 10mm copper pipe. This ensures a secure, watertight compression seal without requiring you to solder new fittings or change the valve choice.

The choice between Angled and Straight valves depends entirely on your pipework position relative to the radiator inlets. If your central heating pipes come up from the floorboards and the radiator has side connections, you must use the Angled Loge valve to create the 90 degree turn required. If your pipes run along the skirting board or come up from the floor to connect to the bottom underneath connections of a ladder rail, you technically require the Straight Loge valve to allow the water to flow in a straight line without a bend.

Yes, the 10 year guarantee provided with the Loge Square Manual Valve covers both the mechanical integrity of the brass body and the quality of the finish, whether it is Polished, Anthracite, or Brushed. Modern plating and powder coating techniques are used to bond the finish to the metal. However, to maintain this guarantee, you must avoid using abrasive acidic cleaners or scouring pads which can technically compromise the clear coat. The problem of finish degradation is almost always solved by cleaning only with a soft cloth and warm soapy water.

Manual valves like the Loge range are mechanically simpler than thermostatic valves and are inherently bi-directional. This means the internal washer mechanism works effectively regardless of whether the water flows in through the inlet or out through the inlet. This solves a common installation headache where the plumber might not know which pipe is the flow and which is the return. You can install the wheelhead on either side of the radiator, although standard practice suggests placing the adjustable head on the flow pipe for optimal noise reduction.

The Anthracite finish on the Loge valve is specifically calibrated to match the RAL 7016 (Anthracite Grey) colour standard, which is the most common powder coat used on modern designer radiators. This ensures a precise visual match where the valve appears as an extension of the radiator rather than an add on component. Technically, using a matching finish solves the aesthetic problem of colour clashing, creating a monolithic look that is highly desired in contemporary interior design schemes.

Yes, the Loge Manual Valve set is an effective isolation tool. If you need to remove a radiator for decorating or maintenance, you can turn the manual wheelhead fully clockwise to the closed position and use a spanner to turn the lockshield spindle fully clockwise to the closed position. This mechanically seals both entry and exit points of the radiator. You can then disconnect the radiator nuts and drain only the water inside the radiator itself, solving the problem of having to drain down the entire central heating system.
