Manual Pneumatic/Electric Knife Gate Valve

Manual Pneumatic/Electric Knife Gate Valve

Electric gate valve control the valve by rising and falling the gate. Its gate perpendicular to way of the fluid, and the size of the channel can be changed by altering the relative position between gate and valve seat.
We have many years of R&D and manufacturing experience in the field of Electric Globe Valve, 4-20ma Valve Actuator, Electric Actuator, and can improve the most cost-effective products for you. In the process of years of practice, development and improvement, our company is gradually forming a mature after-sales service system. In line with the customer-oriented principle, we have established a sound modern enterprise system and a complete and effective total quality management system, as well as a prompt and thoughtful pre-sale and after-sales service system. Cooperation with you will help us to market our products and services and at the same time can reflect our own value. With the superior and exceptional service, we are well developed along with our customers.
