You searched for: Non Return Valves

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, creating a quality product that will remain independent for years with no need for replacement.

OPTI-MAX® Replacement Check Valves

Supplier: Optimize

Each ball and seat set is individually matched to ensure a lock-and-key fit. This guarantees three bubbles/minute or less in the industry standard nitrogen bubble test; common acceptable standards are 12 bubbles or less. We have also minimized the ball travel distance within the check valve; less travel distance equals quicker seating and more accurate pump metering. Simply put, tighter specifications make a better valve.
