The ASCO E290D3230SA0000 angle seat valve uses an entry-above-disc design, allowing the medium to help hold the valve closed and soften the closing stroke. This makes it suitable for steam dosing, hot water and frequent on/off applications. The 316L stainless steel body provides corrosion resistance for treated water and cleaning cycles. A PTFE disc seal and PTFE stuffing box support temperatures up to 184 °C. The 50 mm pneumatic actuator weighs approximately 0.8 kg for the complete valve and rotates 360° to position the G1/8 pilot port conveniently. Need a larger bore? The ASCO E290D0330SA0000 is a 3/4" next-size option with entry under the disc for general air and liquid service. Key Benefits Entry-above-disc design helps reduce water hammer 316L stainless steel body for corrosion-resistant applications Compact 1/2" (DN15) size for smaller pipework Suitable for steam applications up to 10 bar 50 mm pneumatic actuator with 360° rotation Kv 5.1 (Cv 5.9) flow capacity Suitable for rapid cycling applications SIL 2 capable per IEC 61508 For pricing and availability, call +966 569 289 544. Who This Product Is Best For This valve is suitable for small steam and hot-water lines in food and beverage plants, textile and laundry steam systems, pharmaceutical utilities and HVAC reheat circuits across Saudi Arabia and the GCC. It can also be used in dosing lines for water treatment and desalination applications where frequent cycling and pressure surges are important operating considerations. How to Use / How It Works Install the valve: Fit the valve in any orientation. Match the flow arrow on the valve body with the line direction and use thread sealant suitable for the application. Connect the pilot air: Connect filtered air or water to the G1/8 pilot port through a suitable 3/2 solenoid pilot valve. Rotate the actuator to access the port conveniently. Set the pilot pressure: Keep pilot pressure at or below 10 bar. The minimum required pressure depends on the differential pressure across the valve. Cycle and test: Operate the pilot valve several times. Confirm that the valve opens and closes fully and check for leaks before normal operation. Frequently Asked Questions What does NC entry above the disc mean on the E290D3230SA0000? The valve is normally closed at rest. Flow enters above the disc, allowing line pressure to help keep the valve closed and helping reduce water hammer during closing. Can it handle steam? Yes. The valve is rated for steam up to 10 bar and 184 °C. What pilot pressure does it need? The maximum pilot pressure is 10 bar. The minimum required pressure varies according to the differential pressure across the valve. Confirm the required value for your application before installation. What is the flow capacity? The ASCO E290D3230SA0000 has a flow coefficient of Kv 5.1 m³/h (Cv 5.9). Is the E290D3230SA0000 normally closed? Yes. It is a 2/2 normally closed angle seat valve with flow entering above the disc. What is the body material? The valve uses an AISI 316L stainless steel body, making it suitable for applications where corrosion resistance is required.
