The WS1 series valves were designed with the world’s water treatment professional in mind, and incorporate many features that are a direct result of feedback from customers. The WS1 valves are manufactured from composite plastics and are designed to provide high flow rates (up to 27 GPM) over a wide range of applications. This provides water treatment professionals a great deal of flexibility in system design and greatly reduces inventory requirements.

Twin alternating water softeners are ideal for uninterrupted and continuous flow of soft water. One of the two resin tanks is always in service, while the other tank is on standby. When the softening capacity is reached in one tank the WS1EE Meter Control Valve will activate service for second tank. The tank containing the exhausted resin will regenerate and be on standby until the active tanks’ capacity is reached.
