Safety Warning

Item Information

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

Features/Benefits:
• Active pilot operated 2/2 way cartridge valve - ensures safe switching
• Various sizes, NG25 - NG125 - allows extremely variable use
• Cavity and mounting pattern according to ISO 7368 (except for size NG125) - for quick and easy integration
• Lower recess in the standardized mounting cavity is no longer required - minimizes pressure losses
• Flow-optimized sleeve - improved energy efficiency
• Fast switching operations - optimized process speed
• Supplied as one unit - facilitates mounting and dismounting
• Short delivery time for most sizes - no warehousing necessary
• Position monitoring and stroke limiter optional

Applications:
• Suitable for general hydraulic applications
