Differential pressure overflow valve with direct setting value display
Hydrolux is a proportional working, p-band controlled overflow valve with low proportional deviation.
Key features
Direct setting scale display
Low proportional deviation
Extremely low noise, current efficient construction
Low friction valve disc center guide
Highest reaction precision due to an inner setting value spring with generous dimensions
