ASCO E290D7450DA0000, Angle Seat type Pneumatic Actuated Valve, G 1in to G 1in, 6 bar
Part No. E290D7450DA0000
The ASCO E290D7450DA0000 is a 1 in (DN25) bronze Series 290 angle seat valve with G 1 threaded ports, rated to 6 bar. It is the low pilot pressure version, opening from just 2.8 bar of pilot air. 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 E290D7450DA0000 is a normally closed (NC) pressure-operated valve designed for applications where available pilot pressure is limited. Its angled seat provides a high-flow path with low pressure loss, with a flow coefficient of Kv 17.7 m³/h.
The valve features a bronze body, AISI 431 stainless steel stem, PTFE disc seal and packing, and a 63 mm plastic piston actuator with a G 1/8 pilot port. The actuator can rotate through 360°, allowing convenient positioning of the pilot connection. The valve internals can also be serviced without removing the body from the pipework.
Series 290 valves are designed for air, inert gas, water, oil and steam applications. The supplied information specifies 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 E290D7450DA0000?
It is a 1 in (DN25) bronze Series 290 angle seat valve with G 1 threaded ports, normally closed (NC) operation and a low pilot pressure version rated to 6 bar.
What media can the E290D7450DA0000 handle?
The supplied information lists air, inert gas, water, oil 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 is the minimum pilot pressure?
The low pilot pressure version is specified to open from 2.8 bar of pilot pressure.
What happens if pilot air is lost?
The supplied information states that the spring closes the normally closed valve when pilot pressure is lost.
How do I choose the E290D7450DA0000 or another Series 290 valve?
Choose the valve based on line size, connection type, pressure rating, medium, temperature, pilot pressure and required operating position. Send your process data and valve part number to General Tech Services LLC for compatibility confirmation.
