The basic Model 700/705 ES diaphragm actuated valves are
hydraulically operated globe valves in the standard oblique (Y) design.
700 ES – Anti-cavitation valves, designed to operate under difficult
conditions while ensuring minimum cavitation damage and noise.
Each valve comprises two major components:
The body seat assembly and the actuator assembly.
The actuator assembly is unitized and is removable from the body
as an integral unit. It consists of both an upper and a lower control
chamber.
Each basic valve can easily be configured on-site, either as a
single chamber control valve (Model 705 ES), or a double chamber
control valve (Model 700 ES). The shaft sub-assembly, in both
single and double chambered versions, is center guided, providing
an unobstructed seat area
