The series BV76 (DN40-DN250)Pressure Independent Balancing & Control Valve and the series of BVR actuator are designed in air-condition system and heating system, such as PAU, AHU, MAU and end-equipment. According to temperature requirement of aircondition area and signals of control system to regulate terminal flowand maintain constant in pipe network. In order to ensure that terminalis not affected by other devices in the net work, keep the system high efficiency, saving energy and stable.

VALVE FEATURES

• Equal percentage flow characteristic

• Keep the pressure difference between the two ends of the regulator constant

• The regulating spool of the valve is driven by Angle stroke, the driving torque is small, the flow range is large and the control is accurate,

and the overall size of the valve is small

ACTUATOR FEATURES

• Adopt 1.3-inch OLED large-screen LCD, no viewing Angle limitation, high brightness, energy saving and environmental protection, realtime display of valve opening and its external control command, about 5 minutes after the automatic hibernation state, and during hibernation prompt position status and control command.

• Original no-open cover interactive two-step valve mode: the first step: through the key control valve in the "counterclockwise full open position" after saving; The second step: control the valve through the button in the "clockwise full close position" after saving; Easily complete valve adjustment. Completely solve the mechanical positioning switch valve position adjustment cumbersome and inconvenient.

• Using 16-bit high-performance CPU, 12-bit high-precision AD conversion chip, built-in unique algorithm, completely eliminate the mechanical back error, greatly reduce the valve position control error.

• The built-in motor control module can control the motor frequency conversion speed regulation to achieve accurate positioning

• Non-contact positioning, modular control unit design, and potting treatment, to ensure the reliable work of components, greatly improve the service life of the product; The interface adopts standard connector, easy to install, debug and replace

• The fault menu prompts in real time (including the fault caused by the actuator is stuck or the actuator switch is not in place due to other reasons), and the fault alarm signal can be output.

• The exchange of valve control commands can be realized through the menu.

• Through the menu can achieve remote control and field control automatic switching, and through the button to achieve any adjustment of the valve position, built-in electronic limit, and prompt limit status.

• Through the menu, the off-valve position can be shifted to the opening or closing direction, which greatly reduces the tedious and inconvenience caused by "ordinary on-switch mechanical positioning" to the field adjustment.

• The system can restore factory Settings by pressing buttons.
