The double seat control valves of type 14с are intended for the control of the working medium flow or pressure.
The control is carried out with the help of changing the passage area by means of translational movement of the double seat spool.
They are not used as shutoff devices.

The control of the control valves of type 14с is carried out with the help of a multi-turn built-in electric actuator with a current
position sensor of the following types:

  • ПЭМ-Б2У (ABS ZEIM Automation);
  • SAR (AUMA);
  • upon the customer's demand.
