ZSHW pneumatic cut-off valve

Summary
WB300 series high performance butterfly valve is a new valve based on absorbing the advantages of different structure of butterfly valve designed on the. This butterfly valve plate sealing surface for the -- -- spherical cambered surface body, sealing mechanism by the system pressure reaches a true dynamic seal, therefore has the cutting performance and excellent durability. Its small size, light weight, manufacturing a wide range, easy to repair and maintenance.
