It is commonly utilized in heating, ventilating, and air conditioning (HVAC) systems. The function of a spring check valve is to ensure that fluid moves in one direction by preventing backflow. It is also referred to as a non-return valve or a one-way valve. The valve operates when there is a difference in pressure, and fluid flows when the inlet side pressure is higher than the cracking pressure, which is the minimum upstream pressure needed to open the valve and allow fluid to pass through. The valve is equipped with a viton seat that made of Thermoplastic which requires good compatibility and sealing. It is important not to confuse spring check valves with swing check valves, as they operate differently. While both valves prevent backflow, a swing check valve operates with a disc, while a spring check valve operates with a spring. Fluid backflow movement closes a swing check valve, whereas spring check valves remain closed by default. The advantages of using spring check valves include protection against backflow damage and ease of use. They can be installed vertically or horizontally if the fluid movement is upwards, with vertical installation requiring mounting. The material used for constructing this spring check valve is stainless steel 316/CF8M, which offers superior protection against rust and corrosion. It has a maximum working pressure of 1000 PSI and two NPT threaded ends with Viton Seats. This valve is capable of functioning within a temperature range of -29°C to 150°C.
