New Slo-Close Plastic Ball Valves Patent Pending thermoplastic gear driven operating nut rotates 360° to achieve a 90° turn of the ball. The result is slow closure and the elimination of water hammer, while maintaining the positive shut- off and reliable service of a ball valve. Components and internal gears of the Slo-Close system are molded of durable Acetal material, and the Set screw is 316 SS. The system is mounted on Colonial’s Full Block True Union Ball Valve , and Super C Sch 80 Compact Valve, both of which have a proven record of quality in industrial process piping, water treatment, commercial plumbing and irrigation markets for over 30 years.
Valve can be actuated by use of a standard Champion Sprinkler or Drain Key for buried applications, or by hand for any other application. Successfully introduced to the Turf Irrigation market in isolation valve applications, the Slo-Close valve will perform in any industry where the avoidance of water hammer is a priority. Do not use for throttling (in partially open position).
