700 Series Large Size Series Engineering - 1

700 Series BERMAD 700 Large Size Series Model: 700-M5, 700-M6, 700-M5L ■ Large scale pumping systems ■ National and municipal water networks ■ Reservoir and dam water level control ■ Industrial water systems 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 Flow Check code "2S” These valves are designed for large flow applications (On-off valve, pressure reducing, pressure sustaining, pump control, level control, check valve, flow control, burst control, emergency shut-off valve etc.), where precise control is needed. Features and Options ■ 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 (optional) □ Cavitation cage (optional) □ 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)

Engineering Data 700 Series Independent Check Feature Additional feature code 2S The Independent Check Feature is an integral, lift type, non slam check mechanism that opens to allow flow in the required direction and smoothly closes drip tight to prevent back flow. The Independent Check Feature is used on various system applications such as: ■ Pump control valves ■ One-way level control valves ■ One-way zone backup valves ■ Pressure regulating valves Principal of Operation Closed Valve Line pressure applied to the upper control chamber of the valve creates a superior force that moves the...
