RALSTON QTVC-2FBA-6-3 Volume Controller

Proprietary pressure balanced, fine-adjustment piston allows for extremely precise, finger-tip control of pressure between 0.03 psi (2 mbar) to 3000 psi (210 bar). Fine-adjust piston, fill, balance and vent valves are in one lightweight, compact unit. Includes handle, Quick-test outlet connections, hoses and adapters.

Low volume Quick-test hose, gauge adapter and process connection can be attached to QTVC without thread sealant or a wrench. Soft seated valves make filling and venting the system precise. Optional padded strap for field use (NPAK-STRP). Perform both ultra-precise low pressure differential or high pressure static pressure calibrations with nitrogen using the same device with an external pressure calibrator.
