Product Description

The BERMAD Model 100DC Hydraulic Control Valve is a hydraulically operated, diaphragm-actuated control valve that opens and shuts in response to a local or remote pressure command. The valve comprises two major components: the body and the actuator assembly. The actuator assembly is removable from the body as an integral unit. It consists of both upper and lower control chambers, providing an Isolated and protected diaphragm. The double-chambered valve operation is independent of valve differential pressure. This develops maximum power, ensuring immediate valve response combined with inherent soft closing.

Technical Data


Bermad - Model 100DC - Operation

Hydraulic Command 1 is applied to Control Chamber 2 through the Manual Selector 3. This creates a superior closing force that moves the Diaphragm Assembly 4 to a closed position. Discharging the pressure in the upper control chamber to the atmosphere causes the line pressure acting on the seal disk to move the valve to the open position.
