Product Description
产品描述
The HTG-QZT series one-piece instrument ball valves provide reliable on/off isolation for instrument lines with compact dimensions ideal for dense manifold installations. The single-piece body construction eliminates body joint leak paths while the floating ball design ensures positive sealing in both directions. Quarter-turn operation enables quick isolation for maintenance, calibration, or emergency shutdown.
