Donjoy Tank bottom valve

Donjoy Tank bottom valve 

Tank bottom valve usually refers to a specially designed valve to control and regulate the bottom entrance or exit of storage, containers or other similar devices. There are two main designs of tank bottom valve -valve core contraction and valve core stretch.

Valve core contraction: This type of tank bottom valve usually uses a cone valve core to reduce or close the valve seat to control the flow of the fluid. When the valve core moves upward, it reduces the valve seat to prevent or reduce fluid flow. When the valve core moves down, it opens the valve seat and allows the fluid to pass. The main advantage of this design is that it can provide good sealing performance.


Valve core stretch type: This type of tank bottom valve usually uses a plate -type valve core, which can stretch or leave the valve seat at the opening to allow fluid flows. When the valve core moves up, it stretches the valve seat, which opens the valve and allows the fluid to pass. When the valve core moves down, it shrinks the valve seat to close the valve and prevent the fluid from flowing. The main advantage of this design is that it can provide a larger circulation area.

Tank bottom valve has a flexible valve combination and various functional configurations, such as:


Sterilization: This configuration usually includes a built -in sterilization device that can kill bacteria and other microorganisms in fluid flowing through valves.

Clamp insulation: This configuration usually includes a clip, which can maintain the temperature of the fluid to prevent it from cooling or heating when passing through a valve.

Linking buffer: This configuration usually includes a damping device that can buffer the impact of the fluid on the valve seat, thereby reducing noise and vibration.
