LEVEL CONTROL AND PRESSURE SUSTAINING VALVE With 3-Way Altitude Pilot Model 753-80 EN/ES

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.
The valve shuts off at a pre-set reservoir high level and fully opens in response
to an approximately one meter (3 ft) level drop, as sensed by the 3-Way altitude
pilot mounted on the main valve.
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.
