Pressure relief/sustaining hydraulically operated control valve that can fulfill
either of two separate functions:
When installed in-line, it sustains minimum pre-set, upstream (back) pressure,
regardless of fluctuating flow or varying downstream pressure.
When installed as a circulation valve, it relieves excessive line pressure when
above maximum pre-set.
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)
