Our non-return valves protect tubing and vacuum systems from backflow when pressure falls in the system. Sealing system eliminates backflow, helping to prevent upstream contamination or damage. These valves are compatible with a wide range of systems, all with different specific levels when dealing with the three main pressure values: cracking pressure, maximum pressure, and back pressure created. Durable steel or plastics are used in all designs, with spring loaded, creating a quality product that will remain independent for years with no need for replacement.
