Three-Way Control Valves Type S3

Details

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 actuators (basic option) or with P1/R1; P3/R3 actuators (upon request) electric actuators, handwheels type 20 or with no drives.

.

 

  • Possibility of reduction in aggressive and toxic fluids emissions to environment through application of bellow seal bonnets or bonnet packings meeting requirements of TA – LUFT.
  • Possibility of performing diagnostics of “valve-actuator” system due to application of smart electro-pneumatic positioners.
  • Possibility of mating with P/R multi-spring actuators (basic option), P1/R1. Full reversibility of actuator operation and changing the spring range with no extra parts, and broad range of electric actuators.
  • Possibility of special executions for oxygen, hydrogen, gas fuels, low temperature mediums (liquid oxygen, liquid nitrogen), acid gases containing H2S; explosive atmospheres as per 94/9/EC – ATEX
