CHX(EP)-724AH electric valve positioner CHX brand NE724/S1 ELECTRO-PNEUMATIC POSTIONER

chx700 type electric valve positioner converts the DC signal of 4-20 ma from the regulator or computer io port into aerodynamic force , and drives the regulating valve by single or double acting cylinder to realize angular displacement or linear displacement. The closed loop control is realized through the cam feedback system, which makes the regulating valve realize accurate angular displacement or linear displacement proportional to the input signal.
