The proportional flow controller PWS10Z-11 is a pilot-operated, normally closed, spring-loaded poppet-type flow control valve.
It is non-compensated and its function is to smoothly control the flow from port 2 to port 1. The energization of the coil opens the pilot stage and oil flows across an orifice to the back of the main piston.
The resulting pressure differential causes the main piston to follow the pilot stage. When combined with a pressure compensator the proportional flow controller can be used as a 2-way flow regulator – for example when required to lift/lower variable loads at the same velocity.
- Stepless adjustment of the flow, depending on the coil current.
- Excellent stability throughout the entire flow range
- Excellent dynamic performance
- External surfaces zinc-plated
- Hardened and ground valve components to ensure minimal wear and extended service life
- Coil seals protect the solenoid system
- Low pressure drop by CFD optimized flow path
- On request: mechanical adjustment of one point of the curve (Version 11, without option M)
- Optional: Soft shift function with extended switching times possible
