Hydraulically operated control valve that controls reservoir filling and reservoir level.
Reservoir filling is accomplished in response to a hydraulically controlled modulating horizontal float that maintains a constant water level, regardless of fluctuating demand.
BERMAD 400 series valves are hydraulically operated, simple and reliable, globe valves with full bore hydrodynamic body providing an unobstructed flow path and superior performance.
The valves balanced rolling-diaphragm assembly is vulcanized with a rugged radial seal disk construction, performing as the valves only moving part.
- High quality construction materials ensure reliable, long lasting operation
- Fully supported and balanced rolling diaphragm – low actuation pressure and excellent low flow regulation performance
- Straightforward design of three major components – easy and simple on-site inline maintenance with minimal down time
- Accurate and reliable level control; prevents reservoir overflows and cut-offs
- Ensures uninterrupted supply to building occupants dependent on the reservoir system for their water needs
- Specially designed for emergency water reservoirs where long standby periods are expected
- Easy to horizontally mount and calibrate lightweight float; simple installation and maintenance, long-lasting smooth and reliable operation
- 2-Way control loop – maintains accurate and stable reservoir level; specially suitable for large surface / low depth tanks
- Straightforward control loop structure with minimal use of accessories and tubing – prevents breakdowns, overflows and vandalism
- Level control of emergency fire protection reservoirs in buildings, including basement and roof-top reservoirs, emergency water storage, etc.
- Priority and backup management of reservoirs
- Constant level control systems where maintaining a full tank level is required
