Needle and Multiport valve Series IV

  • Needle valves and multiport valves separate the process from measuring instruments such as pressure gauges, switches or transmitters.
  • By closing this valve the instrument can be safely dismounted for services like recalibration or replacement.
  • With the vent connection option, the instrument can be vented to the atmosphere by means of the needle valve.
  • Already in the standard version, the multiport valve is equipped with two additional connections.
  • These can be used either as vent connections or for the connection of additional instruments.
  • Through the non-rotating spindle tip, the wear of the sealing elements is reduced. This results, particularly with frequent opening and closing, in a noticeable increase in the service life.

Key features

  • Standard material for hydrogen application is 316 with other materials available on request
  • Low-wear design due to non-rotating spindle tip in the bonnet
  • Low torque and smooth operation of valve handle even at high pressure
  • Enhanced safety due to blow-out proof bonnet design
  • Valve seat tested for leak tightness per BS6755 / ISO 5208 leak rate A
  • Customer-specific combination of valves and instruments (hook-up) on request
  • Through the blow-out proof design of the valve, working safety is improved, especially in applications with high pressure loading.
