ASCO E290D12T0SA0000, Angle Seat type Pneumatic Actuated Valve, G 1/2in to G 1/2in, 16 bar
Part No. E290D12T0SA0000
The ASCO E290D12T0SA0000 is a 1/2" (DN15) stainless steel Series 290 angle seat valve with G 1/2 threaded ports, rated to 16 bar. It is a normally open valve that stays open when pilot air is removed, allowing the line to continue flowing. Genuine ASCO valve, supplied in the UAE by General Tech Services LLC.

The ASCO E290D12T0SA0000 is designed for cooling circuits, flushing lines, bypass loops and other applications where flow needs to continue when pilot air is unavailable. Its normally open configuration closes when pilot pressure is applied, while the angled seat provides a high-flow path with low pressure loss.
The stainless steel body provides corrosion resistance for wash-down, treated water and demanding process environments. The valve uses PTFE sealing and a 63 mm stainless steel piston actuator with a G 1/8 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
-
Confirm the nameplate matches E290D12T0SA0000, 1/2", 16 bar and the normally open configuration. Verify compatibility with the operating medium, pressure and temperature.
-
Install a suitable strainer upstream, position the valve as required and follow the flow arrow marked on the valve body.
-
Connect filtered pilot air to the G 1/8 pilot port through a suitable 3/2 solenoid pilot valve.
-
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 E290D12T0SA0000?
It is a 1/2" (DN15) stainless steel Series 290 angle seat valve with G 1/2 threaded ports. It is normally open, 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 open valve returns to its open position when pilot pressure is removed, allowing flow to continue.
Should I choose the E290D12T0SA0000 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.
