Ball Valve Curb Stops come standard with a 90º operating head and are designed for
low turning torques and high pressures (300 PSIG). The no-lead brass ball is supported by
two Teflon ball seats. Additionally there are two Buna-N o-rings on the Stainless-Steel
blow-out proof stem designed to isolate from line pressure. The end piece joint is
permanently sealed with thread locker. The bubbletight feature at 300 PSIG makes
these valves a better choice than a plug valve when test or operating pressures over
100 PSIG are expected. All Cambridge Brass Ball Valve Curb Stops are available with
a wide variety of end connections and are manufactured to meet or exceed AWWA
C800 (latest version) standard and NSF 61 & 372 standards, except where noted.
