I just acquired a hp steel 120 and it has a din valve on it . It was born in 92 and is current on viz and hydro. The valve says 3442psi on it . First question is , is this a 200 bar or 300 bar valve? Second question is what can I do the cheapest to use it with a yoke reg till next year when I viz it and can just change the valve out if needed then .
