Model 843 – Booster Pump Control and Pressure Sustaining Valve
The Model 843 is a hydraulic active check pump control valve that opens or shuts off in response to electrical signals. The valve isolates the pump from the system during pump startup and shutdown, thereby preventing pipeline surges. While open, it sustain minimum discharge pressure regardless of fluctuating flow.
The BERMAD 800 Series valves are hydraulic operated, piston actuated, oblique pattern, globe valves with seat assembly and double chambered unitized actuator. The valves hydrodynamic body is designed for unobstructed flow path and provides high flow capabilities. They are made of the highest quality materials suitable for different mining applications.
