Threaded Check Valve factory Introduction New Type Spring Lift Threaded Check Valve is a one-way valve. This means it only allows liquid or gas to flow in one direction and does not allow flow in the opposite direction. When liquid or gas enters the valve in the correct direction, the spring compresses back, allowing the valve to open. However, if the fluid flows in the reverse direction, the spring closes the valve, preventing reverse flow. This unidirectional function is critical in many fields where liquid or gas flow needs to be controlled. Therefore, this product is ideal for systems with high flows and speeds. Advantages Good sealing: New Type Spring Lift Threaded Check Valve has passed the sealing test and pressure test, which can effectively prevent fluid leakage and can provide positive sealing under pressure lower than the valve cracking pressure. This allows it to be safely used in hazardous substances or high-risk situations. The spring applies enough pressure when closing the valve to ensure that no liquid or gas can flow out of the pipe. Good durability: stainless steel, brass, cast iron, polyvinyl chloride, and other optional materials make this product suitable for a very wide temperature range. According to the properties of different raw materials, our valves can be compatible with different media. However, these materials have a long service life, reducing maintenance or replacement costs. Simple installation and maintenance: The threaded connection design makes the installation of the check valve easy. Because the springs are adjustable, they can be easily maintained and adjusted with system needs. At the same time, the product is hands-free and does not require gravity or back pressure to operate or drive. This makes the New Type Spring Lift Threaded Check Valve a very convenient and practical choice.
