Product Overview: 

The LXHQ-CL butterfly valve with central line lining adopts the classic central line structure design, the valve plate and the valve seat are coaxial, the opening and closing are flexible, and the sealing performance is reliable. The valve body is lined with a variety of corrosion-resistant materials (such as PTFE, FEP, EPDM, NBR, NR, etc.), which can effectively quarantine the corrosion of the medium to the valve body. It is widely used in various acid and alkali corrosive media or sanitary occasions. It is the preferred product for environmental protection, chemical, pharmaceutical, water treatment, food and other industries.

Product features: 

Central line design, simple structure, easy to open and close, small torque, low flow resistance

The valve seat lining is made of rich materials, which can be customized according to the medium to meet the needs of different working conditions.

Excellent sealing performance, both forward and reverse direction can achieve reliable sealing, and the sealing grade can reach zero leakage

Wide range of application, resistant to strong acid, strong alkali, solvent and other highly corrosive media

Anti-corrosion and anti-penetration design can effectively protect the valve body and prolong the service life of the valve

Can be installed horizontally, vertically and at any angle, easy to maintain
