BERMAD 700 SIGMA Double-Chamber Control Valves offer Minimum Headloss with 3-Way Pilot Regulation, Smooth Non-Slam Closure and Pilot-less Proportional Pressure Reducing

In a previous blog post, we described how as a result of rising awareness about energy savings and environment protection, water supply and distribution systems need to be more efficient and be able to operate optimally at minimum pressures. While single-chamber control valves were traditionally used in these systems due to their cost-efficiency,
