ASCO E290D3550SA0000, Angle Seat type Pneumatic Actuated Valve, G 1 1/4in to G 1 1/4in, 10 bar
Part No. E290D3550SA0000
The ASCO E290D3550SA0000 is a 1 1/4 in (DN32) stainless steel Series 290 angle seat valve with G 1 1/4 threaded ports, rated to 10 bar. It is a normally closed (NC) valve with fluid entry above the disc, a configuration recommended for rapid-cycling steam applications. Genuine ASCO valve, supplied in the UAE by General Tech Services LLC. Pricing is quote-based. Request a quote in under a minute - call +971 6 543 6933.
The ASCO E290D3550SA0000 features a high-flow angled seat designed for low pressure loss and reliable on/off control. Its stainless steel body, PTFE disc seal and maintenance-free stuffing box make it suitable for demanding industrial applications, including steam, hot water and air.
The valve uses a 63 mm plastic piston actuator with a G 1/8 pilot port. The actuator can rotate through 360° for convenient pilot tubing installation, while the valve internals can be serviced without removing the body from the pipework.
Series 290 valves are designed for industrial process applications. The supplied information specifies air, inert gas and steam, with fluid temperatures from -10 °C to +184 °C. Always confirm the medium, temperature, pressure and material compatibility against the applicable datasheet before selection.

Frequently Asked Questions
What is the ASCO E290D3550SA0000?
It is a 1 1/4 in (DN32) stainless steel Series 290 angle seat valve with G 1 1/4 threaded ports, normally closed (NC) operation, fluid entry above the disc and a maximum operating pressure of 10 bar.
What media can the E290D3550SA0000 handle?
The supplied information lists air, inert gas and steam, with fluid temperatures from -10 °C to +184 °C. Always confirm material compatibility with the specific medium and operating conditions.
How is the valve operated?
It is pressure operated. Filtered air or water pilot pressure moves the piston, typically controlled through a 3/2 solenoid pilot valve. The maximum pilot pressure stated is 10 bar.
What happens if pilot air is lost?
The spring closes the normally closed valve, shutting off the line.
How do I choose the E290D3550SA0000 or another Series 290 valve?
Choose the valve based on line size, connection type, pressure rating, medium, temperature and required operating position. Send your process data and valve part number to General Tech Services LLC for compatibility confirmation.
