    Hi,
    I'm looking for an automatic pressure regulator for my 3' tug project. The boat is powered by a PM Research #8 twin cylinder oscillating marine steam engine which seems quite happy running on 30psi or less. I bought a P5B regulator from Microcosmengine.com (China) which was well made but unfortunately, is designed to work optimally under more than 30 psi steam pressure.

    So I'm looking around for who else carries them -- Ministeam.com lists them -- but are out of stock.

    Any other suppliers out there?

    Thanks!

    Yep, that's the one I have. Doesn't handle low pressure (<30PSI) well.

    Hi Nat,

    Have you tried using a different (lighter) spring in the regulator?

    I'm going to try that. I took it apart and am now just trying to locate a spring with less strength.

    thx.
