3-Way Control Valves

3-Way Valves

3-way valves are used for mixing two flows together, or for diverting a flow to or around a device (bypass). In order to produce a consistent flow quantity for stable operation, the pressure drop across both flow paths (inlet to outlet) must be nearly equal. The sleeve type design is constructed with an O-ring around the sleeve. The O-ring is suitable for water or glycol type service, up to a maximum of 300°F. A higher temperature O-ring for use with other fluids, such as oil or for temperatures up to 410°F, is available.

These W910TB Series with Pneumatically-Operated can be used for mixing and diverting. Used for WATER and OTHER LIQUIDS only.
