1. Overview of pneumatic clamp ball valve

Q681F pneumatic clamp type ball valve, pneumatic clamp type ball valve is widely used in municipal construction, farmland water conservancy, thermal power generation, petrochemical industry, metallurgy and mining, fire protection and environmental protection, food, shipping, medicine and textiles and other fields.

Q681F clamp type pneumatic ball valve is powered by compressed air, and the valve stem drives the valve core to rotate 90° in the valve body to achieve a fully open-fully closed action. The property

Product sealing performance is divided into metal sealing and soft sealing. It has the advantages of compact structure, small size, good sealing, reliable operation, easy maintenance, convenient installation and strong adaptability. It can be widely used in petroleum, chemical, light industry, pharmaceutical, paper and other industrial processes.

In the dynamic control system, it is used for remote centralized control or local control.
