Most lockshield valves unscrew and have a brass mechanism which accepts an Allen key to allow for adjustment. This design is intentional so system balancing can remain unaffected by user adjustments.
All our valves can be used with microbore adapters which effectively replace a normal olive. One aesthetic consideration would be that the microbore pipe would not touch the inlet nut sides like standard 15mm pipework would; however this would most likely not be visible in a standard installation where the bottom of the valve was not easily viewed.
To open the valve you need to turn the wheel-head in an anti-clockwise direction. To close the valve, turn the wheel-head in a clockwise direction.
The automatic bypass valve fits between the flow and return pipes near to the boiler, this way you only need one for your entire system - it does not go on the flow/return pipes for each individual radiator.
A thermostatic wheelhead valve should be fitted to the flow-in pipe to avoid radiator hammer.
A bi-directional valve has been designed so that it's inlet and outlet positions are interchangeable. This does not mean that the thermostatic wheelhead valve can be installed with the flow going in the wrong direction. Rather than the valve can be placed in an abnormal position that still accepts flow in the correct direction.
No, bi-directional capability is a design feature of select styles.

Yes. Manual conversions are an option for all our thermostatic radiator valves.
Unfortunately none of our valves can be used for a steam system.
All our radiator valves are be suitable for any water (wet) central heating system irrespective of the heat source/boiler type.
Unfortunately all of our square valves are manual valves.
