Hydraulically operated control valve that controls reservoir filling and reservoir
level. Reservoir filling is in response to a Bi-level electric float switch signal opening
at a pre-set low level and shutting off at a pre-set high level.
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”.
Hֺydrodynamic wide globe valve body provides:
- Higher flow (Kv; Cv) than standard globe valves
- Higher resistance to cavitation damage
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
- 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)
