ASCO E290D08H0DA0000, Angle Seat type Pneumatic Actuated Valve, G 2 1/2in to G 2 1/2in, 6 bar
Part No. E290D08H0DA0000
The ASCO E290D08H0DA0000 is a 2 1/2" (DN65) bronze Series 290 angle seat valve with G 2 1/2 threaded ports, rated to 6 bar. It is a normally closed valve with fluid entry under the disc and closes when pilot air is lost, providing fail-safe shut-off. 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 angled seat provides a high-flow path with low pressure loss and a flow coefficient of Kv 111 m³/h. The bronze body is combined with a brass stuffing box housing, AISI 431 stainless steel stem, PTFE disc seal and packing for air, inert gas, water, oil and steam applications. The valve operates with fluid temperatures from -10 °C to +184 °C.
The valve uses a 125 mm plastic piston actuator with a G 1/4 pilot port. The actuator can rotate through 360° to simplify pilot tubing installation, and the valve internals can be serviced without removing the body from the pipework.

Frequently Asked Questions
What is the ASCO E290D08H0DA0000?
It is a 2 1/2" (DN65) bronze Series 290 angle seat valve with G 2 1/2 threaded ports. It is normally closed, uses fluid entry under the disc and is rated to 6 bar.
What media can it handle?
The Series 290 is designed for air, inert gas, water, oil and steam, with fluid temperatures from -10 °C to +184 °C. Always confirm material compatibility with the specific fluid and operating conditions.
How is the valve operated?
It is pressure operated. Filtered air or water pilot pressure moves the piston, typically through a 3/2 solenoid pilot valve. The specified minimum pilot pressure is 4 bar and the maximum pilot pressure is 10 bar.
What happens if pilot air is lost?
The normally closed spring-return configuration closes the valve when pilot pressure is removed, shutting off the line.
How do I choose the E290D08H0DA0000 or another Series 290 valve?
Choose the valve based on line size, connection type, pressure rating, medium and operating conditions. Send your process data and valve part number to General Tech Services LLC for compatibility confirmation.
