Information

GENERAL

SELN electronic double seat control valve has adopted dual-oriented structure. Compact body structure, S-streamline liquid channel can supply big flow coefficient, wider adjustable range and more exact flow characteristic. It has aseismatic and wearable characteristic because of the fixed top and bottom of core’s guided part. 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, top reliability, high pressure, high pressure difference and liquid containing scum situation.
