operated control valve that controls reservoir filling and reservoir level. reservoir filling is in response to a hydraulically controlled non-modulating bi-level vertical float that opens at a pre-set reservoir low level and shuts off drip-tight at a pre-set high level. bermad sigma en/es series valves...
minimum upstream pressure regardless of fluctuating flow or reservoir level. the valve shuts off at a pre-set reservoir high level and fully opens in response to an approximately one meter ( ft) level drop, as sensed by the -way altitude pilot mounted on the main valve. bermad 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...
