More than six kinds of input control signal selection, you can select switch selection criteria (DC4 ~ 20mA or DC0 ~ 10V) or non-standard (self-setting) control signals through the state. 7 positive and negative effects are optional. 8 with adaptive function, a key set of different caliber, zero and full bit different stroke of the valve. 9 with the state selection switch can be set-off signal, the spool is fully open, fully closed, or hold. 10 high resolution, and through key settings, up to 0.4% of the control accuracy. 11 triple protection, can play a protective role by mechanical, circuit and software to prevent damage to the actuator itself. 12 with mechanical manual and electronic manual functions, make operation more convenient. 13 overload alarm, when an overload Atropisomers, the locator LED blinks immediately and passive contact signal alarm is issued.

As shown below, the system load fluctuations variable flow system, when the system pressure changes, the dynamic balance of the electric control valve ends of the pressure (P1-P3) also changes: ⑴, while imports increased pressure P1 When, (P1-P2) increases, then the upward movement of the electric valve spool, so that P1, P2 between the reduction degree of opening of the valve body to reduce the pressure P2; reduced when the inlet pressure P1, (P1-P2) decreases, which When the downward movement of the electric valve spool, so that P1, P2 between the opening increases, the spool pressure P2 increases. Therefore, regardless of the system pressure how changes, by adjusting the action of the electric valve spool, P2, P3 between the pressure remains constant. Therefore, this valve anti-jamming capability is strong, with a dynamic balance function; ⑵, when the straight stroke electric actuator receives a control signal so that the valve shaft extension A-B to move up and down (or rotary electric actuator receives a control signal so that the valve shaft extension R-rotating), the opening degree of P2, P3 between also change. Regardless of the system due to the pressure difference (P1-P3) to change, P2, P3 between the differential pressure (P2-P3) is always the same, so the opening degree corresponding to any position, the water flow rate are some of its transport, and electric The actual valve flow characteristic and its ideal flow characteristic curve is the same, there is no deviation. So this more traditional electric control valve electric control valve has a better regulation characteristics.
