Prevent backflow: Ensure one-way flow of the medium to avoid backflow.
Reduce noise: Reduce the impact sound and water hammer effect during valve opening and closing through special design.
Automatic operation: relying on the pressure of the medium to automatically open and close, without the need for external control.
Compact structure: easy to install and takes up minimal space.

The Throttle Stop Valve is mainly composed of valve body, valve cover, valve flap, and valve stem. The handwheel applies a certain torque at the upper end of the valve stem. The valve stem is passed to the valve petals to move it up and down along the valve stem axis to realize the full-opening, full-closed movements and regulating traffic functions. The force applied by the hand wheel can be obsessed with the valve seat to reach the sealing state; Location, change the cross-sectional area between the valve petals and the cover of the valve seat, and achieve the purpose of regulating media flow. At the same time, the throttle stop valve does not rub with the valve seat before turning off, thereby reducing the wear of the cover and effectively extending the life of the valve.
The DBB Plug Valve is a high-performance fluid control device. It adopts advanced track-guided technology to achieve low-torque opening and closing and zero-leakage sealing. This valve is specially designed for harsh working conditions and is suitable for key fields such as petroleum, chemical industry, power and long-distance pipelines. It can meet the complex working conditions such as high pressure, high temperature, corrosive media, and frequent operations.
