The construction of the RH-A control valves is based on our standard cavity-free plug valve with chemical resistant PFA/FEP lining. A wide range of materials for housings, plugs, as well as for sleeves or linings are available for different areas of application. If required, the control valves can also be supplied with a heating jacket. Design Characteristics:
  • Different KVS values
  • Individual control characteristics
  • Free passage possible with open valve
  • Equal percentage or linear characteristic line
  • Cost-effective automation
  • Readily reproducible control position
