The K-Rain 6402-RCW RCW 6000 Series Indexing Valves by K-Rain are water flow operated valves which act as a manifold in your watering system. The 6000 line of indexing valves offers exceptional reliability and durability even under the dirtiest water conditions. With a metal die-cast body, the 6000 valves are capable of high pressure applications and are recommended to be used on pump-fed systems or high flow city water systems. The 6000 valve is available in 4 or 6 outlet models that are cammed for 2 to 6 zone operation. With only one moving part (the stem and disk assembly), the valve is easily serviced and maintained.
