The speed of actuation is set by installing the correct orifice in the lines and the valve is closed by spring pressure, which is opposed by hydraulic or pneumatic pressure to keep the valve open.

These springs maintain a constant force on the packing, ensuring it seals over time, even as the rings wear from stem movement. Unfortunately, the increased pressure tends to restrict valve movement, ...
