Inquiry (采购产品): Cooling Water Drain Valves Over the winter months we have been experiencing valve failer due to freezing. Our last incident included the water freezing inside of a ball valve which resulted in the valve cracking and leaking. I was just wondering what a solution could be to this problem. We have thought about drilling out the downstream side of each ball valve to let the water exit. Has this idea been used before? If not what type of valve is primarily used for this area. **** Hidden Message ***** Tyler Longeau Longeau T4N 6A1 CAN Company: NOVA Chemicals Title: Mechanical Enngineer COOP Phone: (403)-314-8162 E-mail: longeat@novachem.com **** Hidden Message ***** longeat@novachem.com
