Valve(s) require freight shipping or free local pickup.  Flat rate freight is quoted for ConUS, other locations by quote.  If you need a quote for your location send me your particulars including commercial v residential, presence of forklift and loading dock.  Freight shipping requires a couple days at my end to arrange.  Thanks for your interest.
