1.6 It can be set by the state selector switch (forward and reverse action).
1.7 The input signal can be set as (DC4～20mA or DC1～5V) with the state selection switch.
1.8 It is easy to adjust the working zero point (start point) and stroke (end point).
1.9 When the power is suddenly cut off, it can ensure that the valve core is self-locking.
1.10 Adopt synchronous belt drive to effectively reduce noise.
1.11 Time-delay protection function, state self-locking can be implemented at rated load, protection can be started immediately when a fault occurs, and time-delay protection can be canceled by reverse operation.
