TDA016EW06B2VXW Parker Hydraulic Proportional Flow Control Valve

TDA016EW06B2VXW - Proportional Throttle Valve - Series TDA

Parker 2-way proportional throttle valves series TDA provide outstanding characteristics like high resolution and reproducibility as well as a favorable price/performance ratio for a reliable and cost-effective operation. The TDA valve is used to control large oil flows. In combination with the digital power amplifier PCD00A-400 the valve parameters can be saved, changed and duplicated.

Technical functionality:
The TDA valve has a 3-stage design consisting of the first solenoid operated pilot stage with a spool in sleeve design, the second pilot stage with the control spring and the sequence spool and as main stage the poppet in the sleeve. The proportional solenoid operates the pilot spool against the feedback of the control spring and controls the position of the sequence spool. The main poppet follows the position of the sequence spool and provides an open area for flow from B to A (optional A to B) in proportion to the solenoid current. The poppet is positioned independently of the differential pressure, which can become as high as the maximum working pressure.
