Electronic control valve that combines the advantages of an excellent modulating, line pressure driven, hydraulic control valve with those of electronic control. In response to signals from the electronic controller, the valve changes its opening position per preset values programmed into the controller. Both the valve’s opening and closing speeds are controllable and on-site adjustable. 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
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
- 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)
