The Aquastar Easy II SM20 automatic backwash valve is an advanced and fully automatic valve that significantly simplifies and makes sand filter maintenance more efficient. This valve independently controls the filtration and backwash process via integrated timer switch positions and, in the version with an additional pressure sensor, can also backwash based on time and pressure, for optimal water quality and efficient use of resources.
The construction is robust and durable, with an ABS housing and UV-resistant diaphragm, making the valve resistant to intensive pool use and chlorinated water. This ensures long-lasting performance and reliability in a variety of installations. Thanks to its versatile compatibility, the valve can easily be connected to virtually all common filter systems, including 1½” and 2″ Praher side- or top-mount valves and retrofitting on existing Ocean V6 valves.
Important features of the Aquastar Easy II include:
-
Fully automatic and time-saving: no manual operation required
-
Flexible: time- or pressure-controlled, tailored to the filter system
-
User-friendly: visual position indicator and emergency manual override included
-

Installation is simple, with BSP threads and glue connections on the top and bottom, while the compact dimensions (d50) and lightweight construction enable trouble-free mounting. This makes the valve suitable for swimming pools, swimming ponds, and water features where water quality and convenience are paramount.
In short, the Aquastar Easy II SM20 automatic backwash valve from Praher offers a reliable, flexible, and maintenance-friendly solution for efficient sand filter management, making pool maintenance easier, safer, and more effective.
