Expertly crafted from high-grade 316L stainless steel, this check valve is engineered to perform in both low and high-temperature environments. The valve operates by opening when the fluid pressure surpasses the spring's suction pressure. Upon equalization of these pressures, the valve closes automatically. An increase in pressure beyond equilibrium forces the valve to shut, ensuring optimal operational safety.
