Characteristics
The series of active pilot operated 2/2-way cartridge
valves TDW enables to open and close the main poppet
solely by pilot pressure, independent of pressure build-up
in the main ports A and B.
The main poppet is designed hollow and mostly pressure
balanced. The operation is accomplished via minimal
control surfaces resulting in low pilot oil demand and fast
switching operations.
TDW is supplied as one unit to ensure easy installation
– sleeve and body are screwed together. Additionally,
the lower recess in the standardized mounting cavity is
no longer required, providing the possibility to minimize
pressure losses in the manifold block.
Features
• Active pilot operated 2/2-way cartridge valves
• Cavity and mounting pattern according to ISO 7368
• Flow direction B to A and A to B
• 7 sizes NG25 up to NG100
• Position monitoring optional
• Stroke limiter optional
