**Product Description:**
The **Spring Non-Return Threaded Check Valve** is designed to allow fluid flow in only one direction, ensuring proper system operation and preventing backflow. This valve is ideal for applications involving gas, water, oil, and other common industrial fluids. The stainless steel body and PTFE seals provide excellent corrosion resistance, making it suitable for a wide range of environments.
This check valve uses a spring-loaded mechanism that keeps the disc closed until the pressure from the incoming flow opens it. Once the flow stops or reverses, the spring returns the disc to its closed position, effectively blocking any reverse movement. It is suitable for horizontal installations only, as vertical use may affect the performance due to gravity.
