The pneumatic membrane single-seat regulating valve

The pneumatic membrane single-seat regulating valve of this series of products is based on the advantages of introducing, 

digesting and absorbing the latest generation of regulating valve products in the world, 

applying domestic mature design and manufacturing experience, and combining the actual use and maintenance needs of users on the spot. 

A new generation of specialty products adopts IEC international standards. 

The installation height is 30% lower than the old products at home and abroad, and the weight is 30% lower, 

The flow coefficient Kv value is increased by 30%, saving materials and energy. 

It has the advantages of reliable action performance, accurate Traffic characteristics, 

large adjustable range, small valve seat leakage, stable operation, etc.
