Suction and output speeds are independently controlled with full motor control functions, providing a high 1000:1 regulation ratio.

High energy saving and environmental protection

By using helical gears and auxiliary springs, the power consumption is reduced by 70% compared to conventional rebound designs.

Precision chemical dosing operation

The valve design maintains accurate metering at any flow rate, while the motor regulates discharge and suction speeds to achieve high accuracy (+/-1%), dependent on a highly efficient mechanically driven diaphragm pump design.
