Ball valve LFBV series

manualisolationexplosion-proof

Product overview
LFBV is a manually operated shut-off ball valve designed for liquid, suction and hot-gas pipelines in commercial air-conditioning and refrigeration systems. The valve stem opens or closes the internal flow path and the valve can be used as a maintenance valve for evacuation and refrigerant charging.

Key features

• Straight-through full-bore design to minimize pressure drop.
• Quarter-turn (1/4) operation from fully open to fully closed for quick control.
• Welded valve body and seat to prevent external leakage; chromium-plated ball and high-performance sealing ring; 100% leak tested.
• Bi-directional flow; explosion-proof valve stem design; charging-valve option available.
• Valve body equipped with bracket mounting holes for easy installation.
