The version of the Samson 3766 pneumatic or electro-pneumatic positioner is an electro-pneumatic positioner with a type 6116 I/P converter. Samson 3766 pneumatic or electro-pneumatic positioner adopts die-cast aluminum or stainless steel housing, it is a linear actuator product that conforms to IEC 60534-6 or SAMSON one-piece accessory. Samson 3766 pneumatic or electro-pneumatic positioner has a reversible direction of action, which can be divided into two modes: normal and split-range operation.
The valve positioner is used to control the accurate positioning of the valve so that the valve position has a predetermined corresponding relationship with the pneumatic or electric control signal output by the controller. The valve positioner compares the input control signal with the valve stroke feedback amount, and according to the comparison result, the corresponding pneumatic output signal pressure pst is amplified and output. The output signal of the valve positioner is the input signal of the pneumatic actuator. For double-acting pneumatic actuators, the valve positioner adds a reverse output pneumatic amplifier, which is a double-acting pneumatic output.
