Bermad WW-720-4T Sigma EN ES Large Metal Dynamic Pressure Reducing Control Valve with Electronic Multi-Level Setting (AS5081/WaterMark)

The Bermad WW-720-4T Sigma EN ES is a dynamic hydraulic pressure reducing valve equipped with a pneumatically controlled Multi-Setting Pilot Control (MSPC) unit, enabling remote adjustment of downstream pressure levels via a Technolog Modulo Controller. This cutting-edge control valve allows pressure setpoints to be changed automatically based on a programmed time and flow profile, offering advanced optimization for complex water distribution and municipal systems.

At the core of the system is Bermad’s direct-acting pressure reducing pilot valve, which incorporates all primary two-way control functions into a single compact assembly. The MSPC mechanism adjusts the pilot’s set pressure in real-time based on pneumatic commands, allowing dynamic response to varying demand and time-of-day schedules.

Engineered for reliability and performance in demanding network environments, the WW-720-4T helps reduce water losses, prevent pressure surges, and stabilize downstream pressure—even under rapidly changing supply and consumption conditions.
