Product Brief

Kerotest Stabilizer Valves with Integral Block are designed to reinforce the entire installation by shifting the radial-stress load away from the NPT connections. They are available in both needle and ball valve configurations.


  • Block valves can be installed on either side of the stabilized body, allowing 1/2 turn installation
  • Slotted bolt holes allow for 2-1/8 and 2-1/4 inch bolt spacing
  • 0.375 inch bore for unrestricted passage of process gas
  • Non-rotating stem tip standard on block valves
  • Blow-out proof stem provides a secondary stem seal in the full open position
  • Features a replaceable Delrin© seat, and straight through porting for bidirectional, high capacity flow and easy roddable cleaning of block valves
  • Metal body-to-bonnet and body-to-flange plug with secondary O-ring seals: FKM O-ring seal and PTFE back-up O-ring below the stem threads to protect from corrosion and galling.
  • PTFE gaskets and carbon steel bolts included for manifold installation
  • Optional dielectric barrier creates a non-conductive shield between the instrument and the orifice fitting
