Part No. E290D0450SFB000 | Series E290 | ISO 1 in | Normally Closed | Spring Return
Product Description
A 1 in connection suits medium process lines, heating and boiler-house branches, and larger machine feeds where flow demand is higher while installation space remains limited.
The ASCO E290D0450SFB000 is a pressure-operated angle-body piston valve from the Series 290 range. ASCO describes the Series 290 for general service media including air, inert gas, water, oil, and light slurries, as well as steam and hot water in food and beverage processing.
This model has an ISO 1 in connection, a normally closed (NC) default position, and spring return. The supplied listing does not state a maximum working pressure, so the pressure rating should be confirmed with the GeneralTech Shop team for the intended media and operating conditions.
The actuator can be positioned for 360° access to the pilot port, allowing convenient pilot-line routing during installation. The actuator and stuffing box are maintenance-free, and field servicing can be performed without removing the valve from the pipeline.
A large piloting orifice supports fast cycle times, while the anti-water-hammer and back-pressure-resistant design helps protect the line.
As a normally closed valve, it stays shut by default and opens when pilot air is applied. Releasing the pilot air allows the spring return to close the valve.
Related E290 models include ASCO E290D3450SA0000 (1 in, NC, 10 bar) and ASCO E290D3430DA0000 (1 in, NC, 10 bar).
