FLOW CONTROL VALVE Model 770-U EN/ES

Hydraulically operated flow control valve that maintains pre-set maximum flow,
regardless of fluctuating demand or varying system pressure.
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.
