Spring Loaded Check Valve incorporates a spring to assist in closing the check valve. They are designed to close prior to fluid flow reversal. Preventing backflow eliminates the hydraulic shock also known as water hammer.
Spring-loaded check valves are one-way valves that use an internal spring to close automatically when flow stops or reverses. They are ideal for systems requiring quick shutoff and minimal backflow, often used in pump discharge lines and compressed air systems.
