Inquiry (采购产品): Fusible link shut off valve Hi, I need some fusible link valves to install on the bottom of some 75 gallon oil storage tanks. The size is 3/4" and some are 1 1/2". I also have a sight glass in each that is made of plastic (glass isn't permitted in a food plant) - do you have a method of upgrading these to better protect in the event of fire? Thanks!
