4600 4601 4602 Pneumatic positioner

Overview

4600 4601 4602 Pneumatic positioner is an instrument used in conjunction with pneumatic control valves. It is a product imported from American Masoneilan Company by our factory. It accepts the standard air pressure analog signal, which is used to control the stroke of the regulating valve, and the stroke is changed in proportion to the air pressure signal through the feedback system, so as to ensure the correct positioning of the valve.

Feature

4600 4601 4602 Pneumatic positioner is equipped with 2 F pneumatic actuator, type 35002 eccentric rotary control valve, etc.; Type 4600A pneumatic valve, positioner is equipped with linear pneumatic film actuator, which can overcome the friction of the valve stem and eliminate the control valve. Unbalanced force affects, improves valve action speed, improves valve stem displacement accuracy and realizes split-range control, so it is widely used in the automatic control system of petroleum, chemical, metallurgy, power station, light and textile industries.
