GF Piping Systems has introduced the Type 514-519 High Flow Diaphragm Valve Series. The valves are designed to provide a true break-through for weir style valves. The valve features an optimized, turbulence-free flow geometry that offers significantly increased flow rate performance and lower energy consumption, according to the company. These features expand the valve’s suitability for applications where diaphragm valves were previously not considered due to flow restriction.
Camfil Air Pollution Control (APC) says its new HemiPleat® Synthetic dust collector filter combines a high-efficiency synthetic media with proprietary open-pleat technology for excellent performance and long life in harsh, humid environments.
