Choked flow in pneumatic systems occurs when air velocity reaches sonic speed (Mach 1) at the narrowest point of a flow restriction, creating a flow rate ceiling that cannot be exceeded regardless of upstream pressure increases.
Sonic conductance in pneumatic valves refers to the maximum flow rate achievable when gas velocity reaches the speed of sound through a valve orifice, creating choked flow conditions that limit further flow increases regardless of downstream pressure reductions. This phenomenon occurs when the pressure ratio across the valve exceeds the critical pressure ratio of approximately 0.528 for air.
Pneumatic cylinder cushioning works by gradually reducing air flow as the piston approaches its end position, creating a controlled deceleration that prevents hard impacts and extends cylinder life significantly.
When your production line depends on split-second precision, every millisecond of valve response time matters. A delayed solenoid valve can cascade into costly downtime, missed production targets, and frustrated customers. The difference between a 10ms and 50ms response time could mean the difference between profit and loss. Pneumatic solenoid valve
To calculate pressure drop across a pneumatic valve, you need three key parameters: inlet pressure (P1), outlet pressure (P2), and flow rate (Q). The basic formula is ΔP = P1 – P2, but accurate calculations require considering the valve’s Cv coefficient and flow characteristics using the formula Q = Cv × √(ΔP × SG), where SG is the specific gravity of air (typically 1.0).
