Three- Way Control Valve Type S3
Three-Way Control Valves Type S3 are used in automatic systems and remote control
systems as flow control elements to adjust flow of liquids and gases. Type S3M is
designed to mix two streams of medium, where as type S3R is designed to split one stream
into two. Recommended for application in city-heating and HVAC systems and many branches of industry. They can be delivered with P/R and PN/RN actuators (basic option) or with P1/R1; P1B/R1B actuators (upon request) electric actuators (E), handwheels type 20 or with no drives.
