BERMAD | 400 Series Valves

The Bermad RAM 400 Series is a series of hydraulically-operated, diaphragm-actuated control valves with an internationally patented and registered design.
Its construction combines simplicity and reliability. It practically does not have any of the limitations normally associated with these kinds of products.
The valve has been designed to control various types of irrigation, distribution and industrial systems.
Product features:
Very high flow capacity of the water at low pressure losses. Exceptional stability in closing or in controlling the pressure. Absolutely no surges.
The valve opens at a low inlet pressure.
Highly balanced diaphragm without deformation due to unequal hydraulic forces at closure or when setting.
