ASCO E290D04B0SA0000, Angle Seat type Pneumatic Actuated Valve, G 1in to G 1in, 16 bar

Part No. E290D04B0SA0000

The ASCO E290D04B0SA0000 is a 1" (DN25) stainless steel Series 290 angle seat valve with G 1 threaded ports, rated to 16 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.

The ASCO E290D04B0SA0000 is designed for reliable on/off isolation in demanding industrial applications. Its angled seat provides a high-flow path with low pressure loss, with a flow coefficient of Kv 17.8 m³/h. The stainless steel body provides corrosion resistance for wash-down, treated water and demanding process environments, while PTFE sealing supports operation with suitable process media.

The valve uses a 90 mm plastic piston actuator with a G 1/4 pilot port. The actuator can rotate through 360° for convenient pilot tubing access, and the valve internals can be serviced without removing the body from the pipework.

Series 290 valves are designed for air, inert gas, water, oil and steam applications, with fluid temperatures from -10 °C to +184 °C. The supplied specifications also include PED 2014/68/EU, EN ISO 13849-1 and IEC 61508 SIL 2 compliance/capability.

How to Install & Use It

1. Confirm the nameplate matches E290D04B0SA0000, 1", 16 bar and the normally closed configuration. Verify compatibility with the operating medium, pressure and temperature.

2. Install a suitable strainer upstream, position the valve as required and follow the flow arrow marked on the valve body.

3. Connect filtered pilot air to the G 1/4 pilot port through a suitable 3/2 solenoid pilot valve.

4. Cycle the valve several times, check all connections for leaks and verify the position indicator before putting the system into normal service.

Frequently Asked Questions

What is the ASCO E290D04B0SA0000?
It is a 1" (DN25) stainless steel Series 290 angle seat valve with G 1 threaded ports. It is normally closed, uses fluid entry under the disc and is rated to 16 bar.

What media can it handle?
The supplied specifications list air, inert gas, water, oil and steam, with a fluid temperature range of -10 °C to +184 °C. Always confirm material compatibility with the specific fluid and operating conditions.

How is the valve operated?
It is a pressure-operated pneumatic valve. Filtered air or water pilot pressure moves the piston, typically through a suitable 3/2 solenoid pilot valve. Maximum pilot pressure is 10 bar.

What happens if pilot air is lost?
The normally closed configuration uses spring force to close the valve when pilot pressure is removed, shutting off the line and providing fail-safe operation.

Should I choose the E290D04B0SA0000 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.
