Product overview
VA-3100 floating point drive
When the indoor temperature exceeds the set temperature (refrigeration mode) or is 1 ℃ lower than the set temperature (heating mode), the corresponding valve opening relay acts and operates according to the law of 45 seconds and 15 seconds intermittently. When the indoor temperature is lower than the set temperature (refrigeration mode) or higher than the set temperature (heating mode) by 1 ℃, close the valve relay accordingly, and act according to the law of running for 45 seconds and intermittent for 15 seconds. In other states, all relays do not act and the valve remains unchanged;
VA-3200 analog driver
It can automatically measure the valve body stroke to obtain better control accuracy. The mechanical tightening function after the valve is closed. After the valve reaches the closed position, the actuator continues to operate for 7 seconds (software function), so as to fully close the valve and prevent internal leakage; The direct stroke adjustable driver is adopted, and the accurate output of flow is: equal percentage curve or equal linear curve (the dial switch on the driver can be set freely).
Product features
Die cast aluminum support and PC engineering plastic shell are selected;
Low power consumption, low noise and large output torque;
Flexible combination with valve body, which can meet the needs of different differential pressure;
Hysteresis clutch motor, with hysteresis clutch protection function, can produce stable torque in case of pause, so that the valve can be stationary at any position;
Forward and reverse control: the forward and reverse can be flexibly wired as required to match different valve bodies.
