Product Description The ASCO E290D3230DA0000 is designed for small steam, compressed-air and utility lines where reliable pneumatic on/off control and frequent cycling are required. Its angle seat configuration with entry above the disc helps provide controlled closing characteristics for steam and rapid-cycling applications. Medium enters above the disc, while filtered pilot air operates the 50 mm pneumatic actuator through the G1/8 pilot port. When pilot air is released, the spring returns the valve to its normally closed position. The valve provides a Kv of 5.1 m³/h (Cv 5.9), with a supplied water flow value of approximately 85 l/min at 1 bar differential pressure. The supplied data specifies up to 10 bar differential pressure for air/inert gas and steam. The bronze body is suitable for air, inert gases, water, steam and light oils where the media are compatible with the valve materials. The PTFE disc seal, PTFE stuffing box packing and FPM wiper seal support operation with fluid temperatures from -10 °C to +184 °C. The 50 mm glass-fibre-reinforced PA actuator can rotate 360° for convenient positioning of the G1/8 pilot port. The valve can be installed in any position. For a 316L stainless-steel version with the same general function, compare the ASCO E290D3230SA0000. For a normally open bronze configuration, compare the ASCO E290D1230DA0000.

Who This Product Is Best For The ASCO E290D3230DA0000 is suitable for small steam and utility lines in industrial applications such as: Textile and laundry equipment Sterilisation equipment Food and beverage processing equipment Small process heaters Steam utility lines Compressed-air systems Packaging machinery Air blow-off and pulse applications Water utility systems General industrial automation It is particularly suited to applications where the valve cycles frequently and the operating differential pressure remains within the specified 10 bar limit for air/inert gas and steam. How to Use / How It Works Install the valve: Mount the valve in any suitable orientation, ensuring the flow direction matches the application and the valve installation requirements. Connect the pilot air: Connect a suitable 3/2 solenoid pilot valve to the G1/8 pilot port using filtered air or water as the pilot medium. Set pilot pressure: Select the required pilot pressure according to the differential pressure and the manufacturer's operating curve. Maximum pilot pressure is 10 bar. Position the actuator: Rotate the actuator up to 360° if necessary to provide convenient access to the pilot port. Test before service: Cycle the valve several times under controlled operating conditions and check the connections and valve assembly for leaks. Frequently Asked Questions What is the ASCO E290D3230DA0000? It is a 2/2 normally closed Series 290 angle seat valve with a 1/2" DN15 bronze body and 50 mm pneumatic actuator. What does entry above the disc mean? The medium enters above the valve disc. This flow configuration is designed for rapid cycling and helps reduce water hammer during closing. What differential pressure can it handle? The supplied data specifies up to 10 bar differential pressure for air/inert gas and steam. The maximum allowable pressure is 16 bar. What is the Kv of the valve? The valve has a Kv of 5.1 m³/h and a Cv of 5.9, with a supplied water flow value of approximately 85 l/min at 1 bar differential pressure. Can it handle steam? Yes. The supplied data specifies steam service up to 10 bar differential pressure, with fluid temperatures up to 184 °C. What happens if pilot air fails? The spring-return actuator closes the valve, providing normally closed operation. What pilot pressure is required? The required pilot pressure depends on the differential pressure and the manufacturer's operating curve. The maximum pilot pressure is 10 bar. Should I choose bronze or stainless steel? The E290D3230DA0000 uses a bronze body for compatible utility and industrial media. The E290D3230SA0000 provides a 316L stainless-steel alternative. Is there a normally open version? Yes. The ASCO E290D1230DA0000 is a bronze normally open configuration. Confirm the exact application requirements before ordering. Where can I buy the ASCO E290D3230DA0000 in Saudi Arabia?
