The ASCO E290D3250DA0000 is a normally closed pressure-operated valve designed for rapid-cycling steam, hot water and air applications. Its angled seat provides a high-flow path with low pressure loss, while the bronze body, AISI 431 stainless steel stem and PTFE disc seal provide a durable configuration. The valve uses a 63 mm plastic piston actuator with a G 1/8 pilot port that can be rotated through 360° for convenient tubing access.
The valve can be serviced in-line without removing the body from the pipework. Series 290 valves are designed for air, inert gas and steam applications, with fluid temperatures from -10 °C to +184 °C. The E290D3250DA0000 is also suitable for rapid-cycling steam duties where reliable pneumatic on/off control is required.

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 E290D3250DA0000?
It is a 1/2" (DN15) bronze Series 290 angle seat valve with G 1/2 threaded ports. It is normally closed, uses fluid entry above the disc and is rated to 10 bar.
What media can it handle?
The supplied specifications list air, inert gas 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.
Should I choose the E290D3250DA0000 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.
