STEM TYPE

SEALEXCEL Needle Valves are available with a choice of the optional stem to provide greater flexibility.

  • NON-ROTATING (NR): It is Standard self-centring non-rotating stem tip typically used in high cycle application to extend the valve life.
  • V-STEM (VS): It is used for general purpose liquid and gases.
  • SOFT SEAT (SS): A soft seat stem requires a lower sealing torque, It is replaceable and suitable for temperature upto 120ºC
  • REGULATING STEM (RS) : It is used where some degree of flow control required.
