First, the characteristics of EDRV dynamic balancing electric regulating valve :

EDRV dynamic balancing electric regulating valve is a new generation product which is different from the traditional electric regulating valve. It is a product integrating dynamic balancing and electric regulating. As shown in the figure below, in a system that meets a fluctuating flow system, when the system pressure changes, the pressure difference P1-P3 of the second stage of the EDRV dynamic balancing electric control valve also changes.
(1) When the inlet pressure P1 rises, P1-P2 increases. This is the upward movement of the electric valve spool, which reduces the opening between P1 and P2, and the spool pressure P2 decreases. When the inlet pressure P1 decreases, P1-P2 The gap is increased, and the spool pressure P2 is increased. Therefore, no matter how the pressure of the system changes, the pressure difference of the P2 and P3 keys remains unchanged through the adjustment of the electric valve spool. Therefore, this electric valve has strong anti-interference ability and has the function of dynamic balance;
(2) When the electric actuator receives the control signal to rotate the valve shaft in the direction of R, the opening degree of the P2 and P3 keys also changes. No matter how the system pressure difference P1-P3 changes, the pressure difference P2-P3 of the P2 and P3 keys does not change in the formula, so corresponding to any opening position, the water flow rate is constant, and the electric control valve The flow characteristic curve is consistent with the flow characteristic curve of no later than no later, and there is no deviation. Therefore, this type of electric regulating valve has better regulating characteristics when turning to the traditional electric regulating valve .
