Double Dump Valve Keeps Plastics Process Flowing Smoothly for Canadian Chemical Manufacturer

Posted by Tom Hobson on Dec 20, 2011 6:57:16 AM

Whether it’s a trickle, rotary, double flap or double dump valve, choosing the right dry material handling valve can significantly improve the efficiency of your facility’s operations. For example, a specialty chemical manufacturer based in Canada recently discovered a problem with the rotary valve used in the dust collection system of a plastics process. During the collection of a mixture of fine plastic powder and fibrous resin, strings of plastic resin were getting wrapped around the vanes of the system’s rotary valve—causing premature valve damage and drastically reducing the efficiency of the dust collection system. To solve this problem, the manufacturer replaced the rotary valve with a GatorGate™ Double Dump Valve. This valve discharges material while maintaining a positive airlock seal through a pair of sequentially timed flap gates. As the double dump valve’s internal gates open and close, the strings of resin no longer wrap and bind the valve as they did with the old rotary valve. In addition, the new valve minimizes the amount of air leakage in to the system, improving the overall performance of the dust collection system. To learn more about this technology, watch our double dump valve in action.
