New Electric Diaphragm Valve Offers Fast Cycling

Source: 7/8/2020, Location: North America

GF Piping Systems (GF) has introduced the eDIASTAR 5-Series Diaphragm Valve with the dEA Smart Actuator, an innovative 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’s Valve and Actuation Product Manager. “GF’s 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.”

The new valve was introduced in response to growing market demand for complete plant-wide automation. 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 plant efficiencies. The valve can be controlled as open/closed, 4-20mA positioning, Profibus or Modbus.

Available materials are PVC, CPVC, Polypropylene, ABS, and PVDF in sizes 1 and 2-inch (d32 and d63). Pressure rated at 150 PSI, end connections can be ordered in socket, threaded, flanged, fusion socket, or fusion spigot. Durable, all- plastic construction without metal screws prevents 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 important 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. Plant operators can connect to the electric actuator via Direct Wifi through a smart phone or tablet to simplify planning, installation, commissioning, local control, and troubleshooting.
