Look at Clack and Fleck valves. The Fleck 5600 valve is an industry standard and has been for many years. Solid and reliable. The Clack WS-1 series is a very solid, dependable, simpel and easy to service electronic demand metered valve. Stay away from big box store brands. Kinetico also makes some very nice equipment but you have to have it installed and serviced by a Kinetico dealer.
