KST-Series Sample Valve
PostedJanuary 10, 2022
UpdatedJuly 22, 2025
ByFluid Life
For Pressurized Systems
The KST style sample valve, popular with Mobile Equipment OEM’s, uses a 2mm probe that is compatible with SOS,
Probalizer, and Quick Draw valves. Sample valves reduce the time needed to extract a fluid sample and help to avoid external contamination while gaining a more representative sample for more accurate oil analysis trending.
Applications
Features
- Reliable dual sealed design tested at 7800 psi for one million cycles
- Patented elastomeric vacuum tight valve seals
- A variety of disposable and reusable probes are available
- Very low purge volume
- Higher flow for low pressure applications
- Carbon steel with corrosion resistant zinc nickel plating
Specifications
- Sampling Range: 5-4000 psi (0.03 – 27.6 MPa)*
- Working Pressure: 6000 psi (41.4 MPa)
- Seal Material Temperature Range:
- Nitrile: -40C – 115C (-40F – 239F)
- Viton: -26C – 204C (-15F – 400F)
- Valve Material: Carbon steel with corrosion resistant zinc-nickel plating
- Valve Overall Size (L x W): 1.5” x 0.78” (approx.)
*Sampling pressures greater than 750 psi (5.17 MPa) is probe dependent.
