Review on 1 Inch Beduan Brass Electric Solenoid Valve, 12V Normally Closed Air Valve For Water, Gas, Fuel, And Oil by Eric Rodriguez

I keep getting sucked into this quagmire, While these valves are advertised as 1/2 in. NPT ports in the details, (all sizes say NPT in details), these valves all are British BSPT straight threads and NPT nipples or male pipe will bottom out and not seal correctly. I had seen the feedback about the problem with less detail. I shot craps knowing that I was using very low pressure and could use an adapter if necessary. You can buy these. I have before when this happened. Your first hint of trouble is that the AC voltage is listed as 110 Vac - - and this is the Chinese AC line voltage when not 220V. I live in China part of the year. China uses mostly BSPT threads in their plumbing. This seller is trying to hawk Chinese valves in the USA and he knows better. By the way, if used with "ON" duty cycle that is high, these valves will run hot and not be reliable when run on USA 120 Vac line or even higher is worse. Most USA line voltage is now approaching 130 Vac,, Look out for that too. Safety, possible flood and fire issue.
