HSV10, HS20 & Return Valves

For flood-ebb irrigation in a single pipe system

DGT by Senmatic has developed the HSV10 and HS20 valves for perfect irrigation of flood-ebb benches. With the HSV10 and HS20 valve you can get water on the benches and drain it off again through one valve. The valve ensures a regular flling of the benches.

The return valve comes in 2 different sizes, 45 and 90 liters/minutes. The amount of drained water running to the return valve depends on the composition of the system and is a key factor for the choice of return valve.
