        I am thinking of using a gas valve for the regulator on my Black 5 in 5".

        Only trouble is cannot see how the best way to fit it.

        I can see it's easy to make a handle in place of the plastic one.

        Must be a way of connecting Regulator but at moment have no idea at all how it can be connected.

        Also how you connect the front part for the steam any idea's please

          Well after a lot of thinking and searching found i had bought the wrong gas valve from screw fix.

          The one i needed was a 90deg one so as the top goes for the feed front goes to Super heater and the Regulator handle can be just a 1/4 rod with a groove through held with a 8 BA nut and bolt.

          Any one who has used them say how reliable they are so simple to fit in my black 5 another problem solved.

          Thank you Fizzy for advice and help much appreciated.

              Hi Ron – Glad you sorted out the problem but it seems that all the readers have is a one sided conversation with yourself – Would it be a possible help to others who are contemplating the use of these valves to have the knowledge of what help “Fizzy” gave you. frown

                  OK Kwil – Hi Fizzy hope you are reading this as I would like any help you could give on using Gas Valves for regulators – I am contemplating the use of one on the loco I am building 🚂

                    What … each and every individual who may have some passing interest in the subject ?

                    Seems a funny way to organise a forum dont know

                      To use a 90 deg gas valve in my Black 5 it just so easy and so many regulators leak and unreliable.

                      I had heard others who had used them saying how reliable they where but never new how they could be used.

                      With this one its just so easy as a 1/4 rod with a groove in to sit the end on the tap once plastic removed.

                      Then one end with a 10mm Brass tube going to the Super heater.

                      The other is the feed pipe going up.

                      what could be simpler and more reliable plus at £5.99 if ever it did go wrong easy to change and cheap.

                      This was the best Idea that suits me totally i am more for reliability than keeping to stead and hard drawings as i wasn't to use it on a regular basses.

                      I hope this helps others as much as it has helped me.

                          Pipes not to size or fitted same as Regulator rod not the one i will use but as i have been asked for diagram thought this would be simpler and self explanatory.

                            only just seen this, but ron has it in the bag! their operation is so smooth and reliable. Others have posted that they simply do not work – these are the posts of arm chair pundits who know no better. They do work and are utterly reliable. Well done Ron, hope the sketches helped.

                                Thank you Fizzy yes I have now seen a Loco a Britania who uses one.

                                He had the original one on that gave loads problems so changed to gas valve his words Brilliant now.

                                Looking forward to fitting as should have my new Boiler from GB Boilers in about three weeks.

                                Thank you again

                                  Thanks for info – Have been looking more into this and going by the details for valves they seem to be rated for max4 bar pressure which is about 58 PSI – the working pressure of the loco is a bit higher than this – is this OK

                                    All i can tell you is that a 10mm is running and often pulls 20 adults on his Britannia with ease.

                                    Their are several using them on 71/4 also with no problems their is lo leaks seal perfect on hydraulic test's.

                                    Not heard of any one who has used one suffering any loss of power hope that helps.

                                    Maybe on here those who already use them can give you more Info maybe talk to Fizzy he is using one successfully on his loco

                                        I recall there are standard and heavy duty valves availible. Mine are rated at 100psi and 120psi respectively. Ive tested them cold at 250psi with no ill effect. Never had one with a problem.

                                          Thanks fizzy – the ones I have checked on are 8mm pipe and so far have not found a high pressure one – will keep looking.

                                            mine was 8mm too, from screwfix for under a tenner. To be honest if it doesnt melt or fall apart im guessing it will hold a lot of pressure. They can be a bit snappy on opening but a delicate touch sorts that out.

                                              Just checked – angled ball valve 8mm in gas fitting section. No idea where I got the above figures from but I remember them correctly. Hope this helps.

                                                I also bought the 8mm but have also bought a 10mm as thought i had loads of room so thought i would try a larger one.

                                                I am not sure it is needed but i looked at size of pipes going to cylinders and thought i would use the larger one.

                                                A friend at our Club is using a 10mm on his britania 5" works brilliant so went down the same road.

                                                  I bought a 8mm but since also bought a 90 deg 10mm as that is what the other guy is using on his Britannia 5" and would pull a shed down

                                                    The fittings are £5.99 from screw fix same price for 8mm or 10 mm straight or 90 deg.

                                                    Order one day their the next i had bought the 8mm but as i had loads of room now bought the 10 mm.

                                                    I think whatever pressure your loco makes it will take as being Gas valves they are built to withstand double the pressure so i am told for safety reasons.

                                                    I would say they will take more than most home made regulators from what i have seen in my limited experience.

                                                      Pressure is one thing – but are they rated for steam temperatures?
