Components and Operational Mechanism

Valve Body: Available in carbon steel and stainless steel 304, the valve body is designed to withstand the harsh conditions typical of corrosive environments. The choice of material ensures compatibility with a wide range of media, providing a sturdy and reliable housing for the valve's internal components.

PTFE Lining: The interior surfaces of the valve are lined with PTFE, a material renowned for its chemical resistance. This lining serves as a barrier against corrosive substances, protecting the valve body and ensuring the purity of the media.

Solid PTFE Ball: The core check mechanism of the valve, this solid PTFE ball leverages gravity to situate itself in the optimal position for preventing backflow, responding efficiently to changes in flow direction.

The Fluorine Check Valve's operational mechanism is ingeniously simple, relying on the natural movement of the solid PTFE ball to control flow. When fluid pressure from the upstream side propels the ball away from the seat, the valve allows flow. Conversely, when flow ceases or reverses, gravity and reverse flow pressure reposition the ball against the seat, effectively sealing the valve and preventing backflow.
