TDA032 Parker Proportional Throttle Valve 350bar

Product Overview

Models such as TDA032EW09B2NXW, TDA016, TDA025, TDA032, TDA040, TDA050, TDA063, TDA080 and TDA100 belong to the Parker TDA series of proportional solenoid throttle valves (slip-in cartridge 2-way proportional flow control valves). Designed to ISO 7368 cavities, they use a proportional solenoid to control the pilot stage that positions the main poppet. Every unit undergoes rigorous 100% simulated operating-condition testing and offers excellent drop-in interchangeability with equivalent proportional throttle cartridges. High-precision flow regulation and low hysteresis make them ideal for proportional flow control in high-flow hydraulic systems.

Key Technical Advantages

1. High-flow precision regulation: Covers NG16–NG100 with nominal flows up to several thousand L/min, meeting heavy-duty high-flow system requirements.
2. Low hysteresis and high repeatability: Hysteresis <3% and repeatability <1% support accurate proportional flow control.
3. Excellent drop-in interchangeability: Strict compliance with ISO 7368 cavity standard allows direct replacement of equivalent Parker or other brand proportional throttle valves, minimizing modification costs and downtime.
4. Reliable pilot control: Proportional solenoid drives the pilot stage so that main poppet position is proportional to current, delivering fast response.
5. Flexible flow direction and seal options: Supports A→B or B→A flow direction; NBR or FKM seals available.

Application Areas

Large presses, injection moulding machines, die-casting machines, metallurgical equipment, marine hydraulics, mobile machinery and other medium-to-high-pressure systems requiring high-flow proportional throttling.

Expert Maintenance Tips

1. Ensure the cartridge cavity is clean and undamaged before installation; fit seals correctly and install using specified tools and torque.
2. Maintain fluid cleanliness to ISO 4406 18/16/13 or better; use hydraulic fluids compatible with the installed seal material.
3. Use shielded cables for electrical connections and ensure amplifier compatibility; check the pilot oil circuit before first start-up.
4. Periodically inspect the valve body and connectors for leakage or overheating; clean and protect during long-term storage.
5. Do not disassemble the main poppet or pilot stage. Service must be performed only by technicians experienced with Parker cartridge valves; always perform functional and response tests before returning the valve to service.
