Electronic Sleeve Control Valve
GENERAL
SEZL electronic sleeve control valve has adopted sleeve-guided, pressure balanced dual sealing surface and single sealing surface structure, Compact body structure, S-streamline liquid channel supply big flow coefficient, wider adjustable range and more exact flow characteristic. The control valve matched actuator which can receive ON-OFF or 4-20mADC or 1~5V direct signal to take percentage act. It’s widely used for good dynamic stability, low noise, high/low temperature and high differential pressure liquid situation.
