Valve Materials of Construction

Nitronic 50:

  • Good resistance to chlorides, sulfuric acid, and sea water.
  • Resistant to sulfur gases such as hydrogen sulfide and sulfur dioxide

Hastelloy C:

  • Recommended for corrosion resistance
  • Excellent resistance to most acids including formic acid, wet chlorine, and brine solutions

P Type:

  • Standard rotor
  • Composite of PTFE and carbon
  • Standard operation up to 175 C 400 psi

E Type:

  • Standard rotor
  • Composite of polyaryletherketone and PTFE
  • Standard operation up to 225 C 400 psi

T Type:

  • High temperature rotor
  • Composite of polyimide, PTFE, and carbonStandard operation up to 350 C 300 psi

Valve Actuators

Shimadzu System GCs use Valco microelectric actuators for dependability in a unit as small as an air actuator.

  • Stall sensing circuitry – eliminates problems associated with misalignment
  • No additional gas supply lines required
  • Less maintenance than air actuated valves
  • Universal actuators for simplified replacement
