LEVEL CONTROL AND PRESSURE SUSTAINING VALVE With 3-Way Altitude Pilot Model 753-80-M5/M5L/M6

Hydraulically operated, level control and pressure sustaining control valve that
controls reservoir filling and reservoir level. During filling the valve sustains
minimum upstream pressure regardless of fluctuating flow or reservoir level.
The valve shuts off at a pre-set reservoir high level and fully opens in response
to an approximately one meter (3 ft) level drop, as sensed by the 3-Way altitude
pilot mounted on the main valve.
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

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)
