I am looking for a replacement pressure regulator for a drip system to maintain 20-28 psi (30psi max). I've read that PRVs do not necessarily fail to a limiting pressure. My system is limited by the goof plugs (rated at 30 psi max). Can anyone recommend a regulator that is unlikely to fail to a high pressure (>30 psi)? I am currently spending ~$8 per PRV and would spend considerable more for higher confidence. My supply pressure ranges from 40-70 psi. Thanks for any recommendations.
