The article proposes a generalized mathematical model of the valve, based on the representation of its structural diagram in the form of interconnected viscoelastic elements. According to the proposed method, a pneumatic valve with a seal on the basis of polycarbonate PK-M-3 was calculated. Values of speed of movement of the plate of the valve, at which collisions of elements of the valve seal occur, accompanied by vibration of the whole body, are determined. The analysis showed that the proposed mathematical model with sufficient accuracy simulates the dynamic processes when the pneumatic valve is triggered. The developed mathematical model makes it possible to justify the implementation of accelerated life tests for the failure of valve seals.
