Bermad Model 740 - Booster Pump Control Valve

Double chambered, hydraulically operated, active check pump control valve that opens fully or shuts off in response to electric signals. The valve isolates the pump from the system during pump startup and shutdown, thereby preventing pipeline surges.


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”.

Features and Benefits

  • Hֺydrodynamic wide globe valve body provides:
    - Higher flow (Kv; Cv) than standard globe valves
    - Higher resistance to cavitation damage
  • Iֺn-line serviceable
  • Vֺalves are suitable for working with all types of command:
    - Hydraulic, Electric and Pneumatic.
  • Sֺelf-operated valves that can work without an external source of power.
  • Wֺide 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)

Major Additional Features

  • Fֺix Proportion PRV – 720-PD-M5/M5L/M6
  • Pֺressure management valve – 7PM-M5/M5L/M6
  • 3ֺ-way control – 720-X-M5/M5L/M6
  • Aֺnti cavitation cage – 720-C2-M5/M5L/M6
  • Iֺndependent check feature – 720-2S-M5/M5L/M6
  • Cֺheck valve – 720-20-M5/M5L/M6
  • Sֺolenoid control – 720-55-M5/M5L/M6
  • Eֺlectrically selected multi-level setting – 720-45-M5/M5L/M6
  • Hֺigh sensitivity pilot – 720-12-M5/M5L/M6
  • Dֺownstream over pressure guard – 720-48-M5/M5L/M6
