Diaphragm valve MN-720-PD

hydraulically-operatedpressure-reducingfor water

Overview
Hydraulically operated, diaphragm-actuated pressure reducing valve designed to lower a higher upstream pressure to a fixed lower downstream pressure ratio. The Bermad 700 Sigma Series MN-720-PD is an oblique-pattern globe valve with a seat assembly and a removable double‑chamber unitized actuator. The hydrodynamic body offers an unobstructed flow path and strong modulation capacity for high differential pressure applications, with reduced cavitation and low noise for heavy-duty environments.
