The Denc Valve will work with the vast majority of radiator based central heating systems.
The valve comes with a 5mm connection thread, which is compatible with the
vast majority of modern radiators. If your radiators are over 20 years old,
they may have 6mm connection threads, in which case you will also need to buy
one 6mm adaptor for each valve you order.
Please check the size of adapter you need before ordering!
The main body of the Denc Valve (excluding the side connector) is approximately 33mm high and 14mm in diameter. When properly installed the Denc Valve will protrude no more than 22mm from the end of radiator.
