Emerson’s Food Safe ASCO Series 290 Piston Valve

The ASCO Series 290 is a pressure operated, direct acting angle-body piston valve built for demanding applications. The design offers high flow up and options to handle a wide range of media types and operating environments. The direct acting piston and disc seal design provides tight shutoff in both directions. The rugged watertight actuator is made from tough fiber composite and protected with a double O-ring seal.

The ASCO 290 has a variety of optional features and is approved as food safe (FDA & EC 1935/2004). It can be coupled with the ASCO PositionerD, which allows proportional control to vary and direct the flow rate of a broad range of fluids and gases on pneumatically controlled valves. Onboard LED indicators, design, and construction promise a reliable and long service life.

Suitable for general service applications (air, inert gas, water, oil, and light slurries), the ASCO Series 290 also works for steam, hot water, and auxiliary fluids in the food-and-beverage industry. Optional features include a visual/electrical position indicator and a stroke limiter. Its straight-through body design is available in bronze or stainless steel.
