TDA032EW09B2NXW Parker TDA Valve 350 bar

Product Overview

TDA032EW09B2NXW is an NG32 Parker TDA series 2-way proportional throttle valve reference designed for precise control of large hydraulic oil flows. The TDA series uses a pilot-operated three-stage structure, where the main poppet opening follows the proportional solenoid command for stable flow regulation.

Our TDA032EW09B2NXW is supplied as a compatible replacement for the same Parker TDA valve reference, with attention to cartridge fit, sealing reliability, flow stability, and electrical response. Each unit is checked under simulated operating conditions before shipment.

Key Technical Advantages

• High-flow proportional control: The NG32 size provides 950 L/min nominal flow at Δp = 10 bar, making it suitable for large hydraulic actuators and high-flow industrial circuits.
• Pilot-operated three-stage design: The proportional solenoid controls the pilot stage, while the main poppet follows the commanded position for stable metering behavior.
• Fail-safe and low-leakage function: Parker documentation identifies fail-safe behavior at power failure and leakage-free closing from port B to A.
• ISO 7368 cartridge interface: The slip-in cartridge design supports direct manifold integration and simplifies replacement in existing hydraulic blocks.
• Tested replacement supply: Each compatible unit is inspected for sealing, actuation response, and hydraulic performance under simulated operating conditions.

Application Areas

• Injection molding and die-casting machines
• Hydraulic presses and metal forming equipment
• Industrial hydraulic power units
• Marine, mining, and heavy-duty machinery
• Retrofit projects requiring large-flow proportional throttle control

Expert Maintenance Tips

• Verify the original nameplate before installation: model TDA032EW09B2NXW, NG32 cavity, B-to-A flow direction, 16 VDC solenoid, and NBR seal compatibility.
• Clean the ISO 7368 cavity and mounting surface before assembly; contamination can damage the metering edges and increase leakage.
• Maintain oil cleanliness at ISO 4406 18/16/13 or better, and flush the circuit after major maintenance.
• Confirm X-line pilot pressure. For NG16-NG40 sizes, Parker specifies more than 25% of system pressure to ensure reliable main poppet closing.
• Keep external Y drain pressure at or below 10 bar; excessive drain back pressure can affect response and repeatability.
• During commissioning, bleed the hydraulic system, start at low pressure, ramp the solenoid command gradually, and calibrate the amplifier before full-load operation.
