TDA063 Parker Proportional Throttle Valve 350 Bar

Product Overview

The Parker TDA is a 2-way, pilot-operated proportional throttle valve designed for high-flow industrial hydraulic systems. It is part of Parker’s DIN/ISO 7368 slip-in cartridge valve platform and is available from NG16 through NG100. Parker specifies a maximum operating pressure of up to 350 bar for the DIN cartridge platform.

The supplied product range includes:

• TDA063EW09B2NXW21
• TDA080EW09B2NXW21
• TDA016EW
• TDA025EW
• TDA032EW
• TDA040EW
• TDA050EW
• TDA063EW
• TDA080EW
• TDA100EW

Parker’s ordering system identifies the principal configuration codes as follows:

• E = DIN ISO 7368 slip-in valve
• W = design
• 0 = poppet shape
• 9 = nominal flow code
• A/B = flow direction
• 2 = piloting
• N/V = seal material
• L/X = solenoid voltage
• W = plug socket without plug
• Final code = design-series information.

The TDA design should be distinguished from Parker’s TEA and TDL series. TEA adds a pilot interrupt/shut-off function, while TDL incorporates LVDT position feedback and onboard electronics for higher-performance hydraulic control.

Key Technical Advantages

1. Pilot-Operated Proportional Flow Control

The TDA design uses a pilot stage to control the main poppet, providing proportional flow modulation across large hydraulic passages. This makes the technology particularly suitable for high-flow industrial systems.

2. NG16–NG100 Size Range

The broad nominal-size range allows engineers to scale the valve according to hydraulic flow requirements without changing the overall slip-in cartridge architecture.

3. DIN ISO 7368 Cartridge Integration

The standardized slip-in cartridge concept is well suited to large hydraulic manifolds and integrated press-control blocks, reducing the need for extensive external piping.

4. Selectable Flow Direction

TDA configurations support A → B or B → A flow direction, allowing the cartridge to be matched to different hydraulic circuit architectures.

5. Multiple Seal Materials

Parker provides Nitrile and Fluorocarbon seal configurations, supporting selection according to hydraulic-fluid compatibility and temperature requirements.

6. Digital Amplifier Compatibility

Parker documentation identifies compatibility with the PCD00A-400 digital power amplifier, which can save, modify and duplicate valve parameters for controlled proportional-hydraulic operation.

7. Suitable for Large Industrial Hydraulic Systems

With sizes extending to NG100 and a platform pressure capability up to 350 bar, the TDA family is targeted at applications requiring substantial hydraulic flow rather than small conventional solenoid-valve circuits.

Application Areas

Hydraulic Presses

• Hydraulic presses
• Press-control systems
• Large hydraulic cylinders
• High-speed press circuits
• Industrial forming machinery

Parker’s press-control documentation directly lists TDA016, TDA025, TDA032 and TDA040 as flow-control valve options.

Injection Molding and Die Casting

The TEA variant is specifically intended for high-flow accumulator discharge in:

• Injection molding machines
• Die-casting machines
• Hydraulic presses

Parker describes TEA as a proportional throttle valve with an additional pilot interrupt valve for the safety function.

Industrial Hydraulic Power Units

• High-flow hydraulic power units
• Accumulator systems
• Large hydraulic manifolds
• Central hydraulic systems
• Industrial automation equipment

Expert Maintenance Tips

Verify the complete cartridge configuration.
Confirm nominal size, flow-direction code, pilot configuration, seals, solenoid voltage and design series before replacement.

Do not confuse nominal flow code with actual flow.
In TDA063EW09B2NXW21, 063 identifies NG63, while 9 is a nominal-flow code. It should not be represented as a 9 L/min valve.

Inspect the DIN cavity carefully.
Cartridge performance depends strongly on cavity accuracy, cleanliness, surface condition and alignment. A visually identical cartridge is not automatically hydraulically equivalent.

Verify pilot-circuit connections.
Because TDA is pilot operated, incorrect pilot routing can cause unstable opening behavior or incorrect proportional response.

Control hydraulic contamination.
Clean the manifold cavity and flush the hydraulic circuit before installation. Fine particles can interfere with pilot control passages and poppet movement.

Do not substitute TDA, TEA and TDL solely by physical size.

• TDA: proportional throttle
• TEA: proportional throttle with pilot interrupt/shut-off
• TDL: proportional throttle with LVDT and onboard electronics

These differences affect machine control logic and safety functionality.

Verify electrical data.
For TDA063EW09B2NXW21, X identifies the 16 VDC solenoid option, while N identifies Nitrile seals and B defines the B-to-A flow direction.

Validate replacement valves under representative working conditions.
For replacement supply, a professional engineering test should verify pressure, flow, pilot response, flow direction, leakage, proportional response and thermal stability. This is the appropriate basis for demonstrating in-place interchangeability rather than relying on dimensional matching alone.
