Edrv dynamic balance electric regulating valve, dynamic balance electric two-way valve

Edrv dynamic balance electric control valve is a new generation product different from the traditional electric control valve. It is an integrated product of dynamic balance and electric control.

Working principle of edrv dynamic balance electric control valve:

Edrv dynamic balance electric control valve in the variable flow system with large fluctuation of system load, when the system pressure changes, the differential pressure (P1-P3) at the two ends of the dynamic balance electric control valve also changes:

⑴ when the inlet pressure P1 rises, (P1-P2) increases, then the electric valve spool moves upward, so that the opening between P1 and P2 decreases, and the spool pressure P2 decreases; When the inlet pressure P1 decreases, (P1-P2) decreases, and then the electric valve spool moves downward, the opening between P1 and P2 increases, and the spool pressure P2 increases. Therefore, no matter how the pressure of the system changes, the pressure difference between P2 and P3 will always remain unchanged through the regulation of the electric valve spool. Therefore, the dynamic valve has strong anti-interference ability and dynamic balance function;

⑵ when the straight stroke electric actuator receives the control signal to make the valve shaft move up and down along A-B (or the angular stroke electric actuator receives the control signal to make the valve shaft rotate along R), the opening between P2 and P3 also changes. No matter how the system pressure difference (P1-P3) changes, the pressure difference (P2-P3) between P2 and P3 remains unchanged. Therefore, corresponding to any opening position, the water flow transmitted by it is certain, and the actual flow characteristic curve of the electric balance valve is consistent with its ideal flow characteristic curve without deviation. Therefore, this electric control valve has better regulation characteristics than the traditional electric control valve.

Edrv dynamic balance electric control valve product advantages

1. Stability: the flow change of the terminal equipment is not affected by the system pressure fluctuation, and the flow change does not interfere with each other.

2. Energy saving: save 6-20% energy compared with traditional systems

3. High efficiency: the debugging time is greatly shortened, and the system operation has high efficiency.
