ASCO E290D74X0SA0000 Angle Seat Valve, G 1" (DN25), Normally Closed, Low Pilot Pressure, 316L Stainless Body, 12 Bar
ASCO E290D74X0SA0000 Angle Seat Valve 1" NC | KSA
PRODUCT SUMMARY
The ASCO E290D74X0SA0000 is a 1" (DN25) normally closed, pilot-operated angle seat valve from the ASCO Series 290. It features an AISI 316L stainless steel body, low-pilot-pressure operation and up to 12 bar differential pressure for air and liquids. Steam applications are rated up to 10 bar. The actuator is a special X variant, so its configuration should be confirmed with General Tech before ordering.
PRODUCT DESCRIPTION
The ASCO E290D74X0SA0000 is a 2/2 normally closed pneumatic angle seat valve designed for industrial process and utility applications where reliable shut-off and low pilot-pressure operation are required.
The valve uses a G 1" (DN25) connection and an AISI 316L stainless steel body for corrosion-resistant service. Its angle-seat construction provides a high-flow path, while the PTFE disc seal and PTFE stuffing box support operation with water, air, steam, inert gases and light oils within the specified conditions.
The normally closed design keeps the process line shut when pilot pressure is removed. When sufficient pilot pressure is applied, the actuator opens the valve to allow the process medium to flow.
A key feature of the E290D74X0SA0000 is its low-pilot-pressure function. Function code 7 identifies the valve as a normally closed, low-pilot-pressure configuration, making it suitable for systems where instrument-air pressure may be limited or shared between multiple machines.
The valve supports up to 12 bar differential pressure for air and liquids and up to 10 bar for steam. Fluid temperatures can reach up to +184°C under the specified operating conditions.
The part number contains an X actuator code. According to the supplied source, this is a special actuator variant that is not documented in ASCO's public datasheet. Therefore, the actuator size, material and pilot-port configuration should be confirmed with General Tech before purchase.
For buyers who require a fully documented 1" low-pilot-pressure configuration, the E290D74B0SA0000 is identified in the source as a comparable option with a documented 90 mm glass-fibre-reinforced PA actuator.

WHO THIS PRODUCT IS BEST FOR
The ASCO E290D74X0SA0000 is suitable for maintenance teams, OEMs, system integrators and project engineers working with 1-inch pneumatic process and utility lines.
Typical applications include compressed-air networks, water treatment and desalination skids, oil and gas utility lines, textile and laundry steam systems, HVAC hot-water circuits, packaging equipment and petrochemical auxiliary systems.
It is particularly relevant where the pneumatic control system has limited or shared pilot-air supply and a normally closed stainless steel angle seat valve is required.
Because the X actuator configuration is not fully documented in the supplied source, buyers should confirm the actuator details with General Tech before specifying the valve for a project.
HOW TO USE / HOW IT WORKS
1. Install the valve
Install the valve in the required orientation and follow the flow arrow on the valve body. Properly seal the G-thread connection and support the connected pipework.
2. Connect the pilot system
Connect filtered air or water to the actuator's pilot connection through a suitable 3/2 solenoid pilot valve. The exact pilot-port configuration should be confirmed because of the special X actuator variant.
3. Set the pilot pressure
Keep pilot pressure within the rated range and do not exceed the 10 bar maximum pilot pressure. The minimum pilot pressure for the X actuator variant should be confirmed with General Tech before installation.
4. Check process pressure
Keep the differential pressure within the specified limits: up to 12 bar for air and liquids and up to 10 bar for steam.
5. Cycle and test
Operate the pilot valve several times and confirm that the angle seat valve opens and closes correctly. Check all connections for leakage and verify proper shut-off before normal operation.
FREQUENTLY ASKED QUESTIONS
What does the X in E290D74X0SA0000 mean?
The X identifies a special actuator variant. The supplied source does not document the exact actuator size, material or pilot-port configuration, so these details should be confirmed with General Tech before ordering.
Is the E290D74X0SA0000 normally open or normally closed?
It is normally closed. The valve remains closed without pilot pressure and opens when sufficient pilot pressure is applied. Function code 7 identifies the low-pilot-pressure configuration.
What is the connection size?
The valve uses a G 1" (DN25) connection.
What is the maximum differential pressure?
The maximum differential pressure is 12 bar for air and liquids and 10 bar for steam.
Can the valve handle steam?
Yes. Steam is rated up to 10 bar differential pressure and 184°C within the specified operating conditions. Air and liquids are rated up to 12 bar differential pressure.
What is the maximum pilot pressure?
The maximum pilot pressure is 10 bar using filtered air or water. The minimum pilot pressure for this special actuator variant should be confirmed with General Tech.
What materials are used in the valve?
The main body is AISI 316L stainless steel. The valve uses PTFE disc and stuffing-box seals, an FPM wiper seal and an AISI 431 stainless steel stem.
What is the difference between E290D74X0SA0000 and E290D74B0SA0000?
Both are 1" normally closed, low-pilot-pressure valves with 316L bodies. The E290D74B0SA0000 has a documented 90 mm PA actuator, while the X version uses a special actuator variant that should be confirmed before purchase.
