It is commonly utilized in heating, ventilating, and air conditioning (HVAC) systems. Spring Check Valve also known as a one-way valve or a non-return valve. 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 NBR Seal that can withstand high temperatures of up to 120°C (248°F) and 16 BAR pressure. 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 Brass material. It has a maximum working pressure of 16 BAR (230 PSI) and two BSPP threaded ends. This valve is capable of functioning within a temperature range of -10°C to 120°C.
