Benefits

  • All cast iron and steel components are protected against corrosion by high-quality epoxy coating.
  • Robust and compact steel yoke for straightforward mounting of pneumatic and electric actuators and position switches. A hard anodised aluminium NAMUR adapter plate attached to the actuator allows sensors or solenoid valves to be quickly installed (plug & run).
  • Reliable and service-friendly stem seal: The gland packing is made of PTFE impregnated fibre and can be re-adjusted during operation. There is no need to remove the valve from the piping to replace the packing.
