Single ported Globe Control Valves Type S1B

Details

Single Ported Globe Control Valves Type S1B are used in automatic and remote control installations as flow control elements to adjust flow of liquids, steam and gases. Wide range of material and design versions makes the valves applicable in most demanding working conditions in power generation, petroleum chemistry, heating, chemical industry, metallurgy, etc.

 

  • Possibility of performing diagnostics of “valve-actuator” system due to application of smart electro-pneumatic positioners.
  • Wide range of pneumatic or electrical 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
