Description
Bermad WW753-67 with vertical modulating float Sigma EN ES Level Control & Sustaining Valve
The Bermad 753-67 is a hydraulically operated, level control and pressure sustaining control valve that controls reservoir filling and reservoir level. During filling the valve sustains minimum upstream pressure regardless of fluctuating flow or reservoir level.
Reservoir filling is in response to a hydraulically controlled modulating single-level vertical float that opens slowly from the top water level to fill the reservoir and also sustains the inlet pressure to a set value.
BERMAD 700 SIGMA EN/ES series valves are hydraulic, oblique pattern, globe valves with a raised seat assembly and double chamber unitized actuator, that can be disassembled from the body as a separate integral unit.
The valves hydrodynamic body is designed for unobstructed flow path and provides excellent and highly effective modulation capacity for high differential pressure applications. The valves are available in the standard configuration or with an Independent Check Feature code “2S”.
The 700 SIGMA EN/ES Valves operate under difficult operation conditions with minimal cavitation and noise. They meet size and dimensions requirements of various standards.
