The Compression Spring used in a pressure control valve controls the pressure of the fluid passing through the valve. In a pressure control valve, a compression spring is used to control the pressure of the fluid passing through the valve. The spring must also be designed to provide a consistent force over the entire range of compression, to ensure that the pressure control valve operates correctly.Attributes:• Able to withstand the high pressures and temperatures that are present in the valve.• Direction of the coil is right hand and the Total coil is 20 with the active coil 18Applications:The Compression Spring used in the pressure control valve is typically located inside the valve body and is compressed by the fluid pressure. As the pressure increases, the spring compresses, which in turn reduces the flow of fluid through the valve.
