ASCO™ 329 Solenoid Operators (NEMA Types, CSA)

The ASCO Series 329 is the same RedHat II molded epoxy solenoid operator used on general purpose ASCO valves. It has a 3-way solenoid operator and can be used with air, inert gas, water, and light oil media. The 329 Series enables equipment designers to use ASCO coils and operators in customized manifolds and equipment configurations.

• Standard operator: RedHat II watertight, Types 1, 2, 3, 3S, 4, and 4X
• Optional features: Explosion-proof and watertight, Types 3, 3S, 4, 4X, 6, 6P, 7, and 9
• Ambient temperature range: 32° F to 125° F (AC); 32° F to 104° F (DC)
• Optional inserted seat is available

1. Wide Valve Compatibility

· Complies with the ISO 5211 direct-mounting standard, allowing it to drive most brands of angle seat and ball valves without adapter plates, offering exceptional versatility.

2. Diverse Protective Enclosures

· Available with multiple enclosure options: NEMA 1 (General Purpose), NEMA 3R (Raintight), NEMA 4 (Splashproof), NEMA 4X (Corrosion Resistant), NEMA 7 (Explosion-Proof), meeting installation requirements in different environments.

3. High Torque Output and Reliability

· Compact design delivers sufficient torque to ensure reliable valve opening and closing. Utilizes high-quality ASCO electromagnetic and mechanical components for long service life.

4. Flexible Voltage and Control Options

· Supports various AC/DC voltages (e.g., 24V DC, 110V AC, 220V AC) and can be configured for single solenoid (spring return) or double solenoid operation to suit different control logics.

5. Easy Installation and Maintenance

· Modular design facilitates simple installation. The coil can be replaced quickly, ensuring low maintenance costs.

· Water Treatment Systems: Controlling angle seat valves for water and chemical on/off.

· Steam & Hot Water Lines: Automated control.

· Food & Beverage Processing: Valve control for processes like CIP cleaning.

· General Industrial Processes: Fluid control in chemical, pharmaceutical, and energy industries.

· Outdoor or Damp Locations (Require NEMA 3R, 4, 4X enclosures).

· Hazardous Areas (Require NEMA 7 Explosion-Proof enclosure).
