The Compression Spring used in the Pressure Control Valve provides a force to hold the valve in a particular position. When a compressive force is applied, the coils are compressed and the spring stores the energy. The shape of the Compression Spring is cylindrical, with a helical coil that is tightly wound to resist compression.Attributes:• Provides a constant force over a wide range of deflections• Coils of the spring wrap around the axis of the spring in a clockwise direction when viewed from the top Applications:The Compression Spring is used between the plug and the valve to provide a force that opposes the hydraulic force acting on the valve.
