Sample loops are accurately sized for each valve type. Each loop includes fittings appropriate to the tubing size and material.
- Loops for:
Heaters for valves and columns
![heated valve enclosure](images/glam-hve.jpg)
These insulated enclosures allow valves or columns to be operated at temperatures independent of other controlled zones of analytical instruments.
Position feedbacks

Optional position feedbacks are available for manual valves and valves on two position air actuators.
- Position feedback for:
Purge housings
Purge housings for Valco valves eliminate any possible diffusion from the atmosphere into the valve, or safely vent fugitive emissions from the valve.
