Parker's active pilot operated 2/2 way throttle 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. Thus they provide safe switching resulting in reliable operation.
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.
Markets:
• Industrial
• Molding
• Oil & Gas
