BOOSTER PUMP CONTROL VALVE Pressure Sustaining and Reducing Model 743-M5/M5L/M6

Hydraulically operated, pump control, pressure sustaining & reducing 3-Way control
valve. It opens/closes in response to electric signals, isolating the pump from the
system during startup and shutdown, thereby preventing pipeline surges. While open,
it sustains minimum pump discharge pressure to ensure optimal pump operation. It also
reduces upstream pressure to lower constant downstream pressure.
The BERMAD 700 Series large size control valves are hydraulically operated,
diaphragm actuated type. Unique hydro-dynamic globe valve design with a
special open plug provides high flow capabilities. The valves are available in
the standard configuration or with an Independent Check Feature code “2S”.

Hydrodynamic wide globe valve body provides:

  • Higher flow (Kv; Cv) than standard globe valves
  • Higher resistance to cavitation damage

In-line serviceable
Valves are suitable for working with all types of command:
Hydraulic, Electric and Pneumatic.
Self-operated valves that can work without an external source of power.
Wide range of options and accessories:

  • One-way or two-way flow direction
  • V-Port
  • Cavitation cage
  • Visual position indicator
  • Limit switches
  • Analog opening output
  • Large selection of control accessories
  • Double chamber actuation (700-M6)
  • Large inspection and service ports (700-M5L)
