Inquiry (采购产品): vent valve I work for a chemical distributor and have an end user who is looking to install a small tank (100 gallons) for HCl. He was wondering if there are any vent valves to prevent the release of any gases from this tank into the ambient. Do you have any such item or could you point me in the right direction?
