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
