Product Description

The coaxial valve has the characteristics of anti-pollution, high flow, small size, fast response, maintenance-free, back pressure sealing, and long life.

      

| Product introduction

The valve body and actuator integrated structure are adopted, and the actuator coincides with the axis of the fluid pipeline to minimize the installation space and minimize the influence of fluid pressure difference on the valve opening force. Used to control various media, gaseous, liquid, gel-like, particulate, highly contaminated and corrosive. Compared with ordinary valves, the design of coaxial valves has the characteristics of controlling high flow and high pressure.
