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)
