The M-Dura™ heavy-duty valve features AccuSet™ piston technology, which requires little maintenance and few replacement parts over its life. The valves are compatible with all commercial applications, regardless of water-pressure variances and usage rates. The valves operate with pressure as low as 15 pounds per square inch, and fluctuations are less likely to cause malfunctions. The piston technology features a self-cleaning filter, which protects piston seals against clogs and damage from line debris, allowing full operation at up to 90 percent clogging.
