Product Description
The ASCO E290D1110SA0000 Angle Seat Pneumatic Valve is designed for compact process and utility systems that require reliable flow control. Its 3/8-inch connection makes it suitable for small-bore circuits, dosing points, sampling lines, laboratory utilities, and pilot plant applications.
Part of ASCO's Series 290 range, this 2-way valve features an ISO 3/8-inch connection with a nominal diameter of 10 mm. It has a normally open (NO) function with spring return and a maximum working pressure of 16 bar.
The valve includes a stainless steel body and PTFE disc seal. Its plastic actuator has a 32 mm piloting size and a G1/8 pilot connection. The valve operates using pilot air, so electrical power is not required at the valve itself.
The angle seat design provides a smooth flow path, supporting efficient flow through compact piping systems.
Normally Open Operation
As a normally open valve, the E290D1110SA0000 allows flow by default. When pilot pressure is applied, the valve closes; when pilot pressure is released, the spring returns it to the open position. This operating principle can suit cooling, flushing, and bleed lines that require flow to remain open when pilot air is unavailable.

How It Works
Install the valve in the line according to the manufacturer's installation instructions and flow direction.
Connect the pilot air supply to the G1/8 pilot port.
Apply pilot air to close the valve.
Release pilot pressure to allow the spring to return the valve to its normally open position.
Check the connections for leaks under the intended operating conditions.
Frequently Asked Questions
Q. Is the ASCO E290D1110SA0000 normally open or normally closed?
It is a normally open (NO) valve.
Q. What is the connection size?
It has an ISO 3/8-inch connection, with a nominal diameter of 10 mm (DN10).
Q. What is the maximum working pressure?
The listed maximum working pressure is 16 bar.
Q. What actuator does it use?
It has a 32 mm plastic actuator with a G1/8 piloting connection.
Q. Does this valve require electrical power?
No electrical power is required at the valve itself. It operates using pilot air.
Q. How does the normally open function work?
The valve remains open by default. Applying pilot pressure closes it, and releasing the pressure allows the spring to return it to the open position.
Q. How can I choose the correct ASCO E290 valve?
Check the connection size, default position, and maximum working pressure. For this model, those are 3/8 inch, normally open, and 16 bar.
