AZBIL Sambu Valve Locator AVP302-RSD3A Type Selection
According to the direction of action can be divided into one-way valve positioning and two-way valve positioning.The valve positioner is the main accessory of the control valve. It compares the valve stem displacement signal as the input feedback measurement signal and the controller output signal as the setting signal. When the two deviate, it changes the output signal to the actuator, moves the actuator, and establishes a one-to-one correspondence between the valve stem displacement amount and the controller output signal.
Working principle of Yamwu valve locator
Yamwu valve positioner can withstand the harsh factory climate, temperature, corrosive offshore environment, high frequency vibration occasions and other places, and in the harsh environment than the traditional locator, more reliable.So the Yamwu cover locator is applicable to a wider range, more suitable places.Click the mode key to switch the locator from automatic to manual mode, press and hold the increase key to achieve rapid increase; press the decrease key, and then press the increase key to achieve rapid reduction.Once the key is released, the actuator stops in its current position, and the internal setpoint is adjusted to the current operating variable.If the locator gas source is lost, in order to maintain the current valve position, the manual control is closed loop, without the influence of the gas source.
