The growing demand for automation in industrial plumbing settings means that even valves which are isolated or not accessible for a compressed air system have to be automated. The eDIASTAR 5-Series Diaphragm Valve from GF Piping Systems is automated, reducing time-consuming manual operations within the facility.

Easy and fast retrofitting of hand-operated valves is possible without disassembly. Thanks to its all-plastic design, it is durable and needs little maintenance, it ensures short downtimes and lower maintenance costs during installation and reduces maintenance costs, even with aggressive and abrasive media. It includes the dEA Smart Actuator, a new electric valve that allows easy and fast retrofitting of GF manual diaphragm valves without disassembly. The eDIASTAR is designed to regulate, close and control volume flows automatically.  

“Diaphragm valves are known for providing very linear flow control, as well as handling media that contains solids,” says Jeffrey Sixsmith, GF Piping’s valve and actuation product manager. “The eDIASTAR Diaphragm Valve is more than twice as fast at cycling than other valves on the market. Additionally, the uniquely designed high-flow valve body does not have the restricted flow associated with most diaphragm valves.” 

With the eDIASTAR, hand operated valves that are isolated or not accessible to a compressed air system, thereby preventing actuation, can now be automated for greater efficiency. The valve can be controlled as open/closed, 4-20mA positioning, Profibus or Modbus.  

It is available in various materials, including PVC, CPVC, polypropylene, ABS and PVDF, in 1- and 2-inch sizes. It is pressure rated at 150 psi, and its end connections can be ordered in socket, threaded, flanged, fusion socket or fusion spigot. It offers durable, all-plastic construction without metal screws to prevent corrosion, ensuring minimal maintenance and short downtimes, even in use with contaminated, aggressive or abrasive media. This makes it well suited for applications in chemical processing, food processing, microelectronics, water and wastewater treatment, power generation, and cooling and control.  

Other key features include position feedback, solid-state position sensing, automated learning mode, lightweight linkage, integrated emergency manual override, and maximum flow and linear characteristic curves for easier control. Facility operators can connect to the electric actuator via direct Wi-Fi through a smartphone or tablet to simplify planning, installation, commissioning, local control and troubleshooting. 800-854-4090;
