Oscillating Valve Damping
Poppet and check valves can naturally resonate, causing unwanted noise, pressure/flow fluctuations, or wear. These problems can be eliminated by precise damping.
Application Examples
In pneumatic valves (as shown below), an Airpot reduces the amplitude of oscillation without affecting the cracking pressure or positioning of the poppet. With Airpot’s low mass, virtually frictionless motion, and minimal air spring at low forces, the steady-state positioning of the poppet is essentially unaffected by the dashpot.
In a vacuum regulator it improves regulation and eliminates noise caused by the oscillating poppet striking the valve seat.
In a patient ventilator it damps the check valve to eliminate downstream pressure fluctuations.
