Product Details
WZG206
Guided diaphragm regulating valve
Electric Linear Stroke Regulating Valve
Product overview
WZG206 electric diaphragm regulating valve is sealed with a "mountain" protruding surface between the diaphragm and the valve body, without stuffing box, the throttling element is an elastic diaphragm, the valve body flow passage is smooth, and the valve body lining diaphragm can be made of corrosion-resistant materials. The regulating valve is equipped with a small, strong and high-precision actuator that receives ON-OFF or 4~20mADC or 1~5V DC signals for proportional action, which is more suitable for occasions requiring corrosion resistance and toxic.
