Hydrotech’s 765 Valve is the perfect transition valve for those dealers still using inefficient fixed-cycle, mechanical meters. It is simpler than setting an alarm clock, just set the time, number of people and hardness. It has a user-friendly LCD display, adjustable cycle times and the ability to manually index to desired cycle position for faster, easier installation and service. http://www.hydrotechwater.com (877) 288-9888
