A spring check valve is designed to prevent the reverse flow of the working medium in the pipeline. The reverse flow is blocked by pressing the valve disc against its seat under the action of the spring and the reverse flow pressure. The valve opens due to the pressure differential of the medium flow in the required direction, with the valve disc moving and compressing the spring.
