Product Description
ASCO E290D03R0SA0000 Angle Seat Valve for Industrial Applications
The ASCO E290D03R0SA0000 is a 2-way, pressure-operated angle seat pneumatic actuated valve designed for industrial machinery and manufacturing processes. With G 3/4-inch inlet and outlet connections, it is suitable for machine supply lines, heat exchanger circuits, cleaning branches, and medium-sized process piping systems.
This valve features a stainless steel body and actuator, a normally closed (NC) default position, and a maximum working pressure of 10 bar. Its normally closed design keeps the valve shut by default and opens when pilot pressure is applied, making it suitable for applications where flow needs to stop in the default position.
Flexible Installation and Maintenance
The adjustable actuator provides 360° access to the pilot port, allowing flexible pilot-line routing during installation. The actuator and stuffing box are designed to be maintenance-free, while servicing can be performed without removing the valve body from the pipework.
Its modular design, large piloting orifice, and low hysteresis support responsive valve operation. The design also provides resistance to water hammer and back pressure, helping support reliable performance in industrial piping systems.
Certifications and Compliance
The ASCO E290D03R0SA0000 is listed with PED 2014/68/EU, EN ISO 13849-1, and IEC 61508 SIL 2 certifications. It also complies with REACH, RoHS, and EAC requirements as stated in the supplied product information.
