ZMAP-10W ZMAP-16W ZMAP-40W Pneumatic bellows seal control valve

Overview of ZMAP-10W ZMAP-16W ZMAP-40W Pneumatic bellows seal control valve

ZMAP-10W ZMAP-16W ZMAP-40W Pneumatic bellows seal control valve is a modified product of pneumatic diaphragm direct connected single and double seat regulating valve, which has the advantages of simple structure and reliable action. The upper valve cover adopts a corrugated sealing structure, which is combined with the packing seal to form a double sealing form, which can safely and reliably prevent the leakage of art media from the valve stem gap. Therefore, it is especially suitable for the regulation of highly toxic, valuable, volatile and radioactive media, and also suitable for pipeline vacuum occasions.

Working Principle of ZMAP-10W ZMAP-16W ZMAP-40W Pneumatic bellows seal control valve

The regulating valve is composed of electric actuator or pneumatic actuator and regulating valve. The regulating valve is usually divided into straight through single seat regulating valve and straight through double seat regulating valve. The latter has the characteristics of large flow capacity, small imbalance and stable operation, so it is usually especially suitable for occasions with large flow, high pressure drop and less leakage .The regulating valve is used to regulate the flow, pressure and liquid level of the medium. The opening of the valve is automatically controlled according to the signal of the regulating part, so as to achieve the regulation of medium flow, pressure  and liquid level. The regulating valve is divided into electric regulating valve, pneumatic regulating valve and hydraulic regulating valve
