BERMAD Waterworks High-Rise Buildings have unique requirements, which must be taken into account when designing and installing their water supply and distribution systems. BERMAD solutions give careful consideration to issues such as: ■ While single source supply is common, supply cut-off is unacceptable. ■ Water damage in a high-rise building can be extremely costly. ■ Valves are often located in close proximity to prestigious residential and office space. ■ The main supply line is exposed to increasingly high head at lower zones. ■ A multiplicity of systems requires integration and control....

BERMAD Waterworks 700 & 800 Series Basic Valve Diaphragm Actuated Valve The basic Model 700/705 diaphragm actuated, and the 800/805 piston actuated valves are hydraulically operated globe valves in either the standard oblique (Y) or angle pattern design. 700 series valves are available in two basic configurations: 700ES – Anti-cavitation valves, designed to operate under difficult conditions while ensuring minimum cavitation damage and noise. 700EN – High capacity valves, full ported and designed to deliver high flow with minimum head loss. Each valve comprises two major components: the body...

BERMAD Waterworks 700 & 800 Series

BERMAD Waterworks 700 & 800 Series Principle of Operation On-Off Modes Closed Position Line pressure applied to the upper control chamber of the valve creates a superior force that moves the valve to the closed position and provides drip-tight sealing. Open Position Discharging the pressure in the upper control chamber to atmosphere or some other lower pressure zone causes the line pressure acting on the seal-disk to move the valve to the open position. Powered Open Position Line pressure is applied to the lower control chamber as pressure in the upper control chamber is vented. This, together...
