Poppet Seals for Demand Flow Regulators

Avoid Leakage and Support a More Accurate System

Poppet seals are sealing elements used to control fluid or gas flow in various applications. They consist of a movable component, the "poppet," that fits snugly against a valve seat to stop or allow fluid to pass through. When the poppet lifts, it opens the flow path, and when it returns to its seat, it creates a seal, stopping the flow.

There are many applications in industrial settings where fluid must be sealed and released in calibrated quantities. Some examples include pressure regulators, relief values, fuel nozzles, or gas metering. Specifically a demand flow regulator is designed for use with various industrial instruments and uses a pump to draw the calibration of gas. It is crucial that there is no leakage of the fluid for the system to operate properly.

Parker Composite Sealing Systems Division designs different poppets to help control leakage in flow control applications. Our poppet is used to help keep the demand flow regulators in the “closed” position. And when the user “demands” gas flow, a diaphragm pushes down on the seat stem of the Poppet to help monitor the flow of gas.
