WebEach set of Crower valve springs comes with an installation card that specifies the correct installed height for your springs. Installed height is the distance from the spring seat on … WebThe reason why a pneumatic control valve’s stem position corresponds linearly to the amount of air pressure applied to the actuator is because mechanical springs tend to follow Hooke’s Law, where the amount of spring motion (\(x\)) is directly proportional to applied force (\(F = kx\)).A pneumatic actuator applies force as a function of air pressure and …
