LFBV is a manually operated shut-off valve, suitable for liquid, suction and hot gas pipelines of commercial air-conditioning, refrigeration and other equipment. By operating the valve stem, it can open and cut off the internal circulation path. It can be used as a maintenance valve for vacuuming and adding refrigerant during maintenance.

Straight through type, full bore design for minimum pressure drop and low pressure loss.
From fully open to fully closed, only 1/4 turn is needed, easy operation.
The valve body and valve seat adopt a welded structure, no external leakage, high reliability.
Chromium plated ball and high-performance sealing ring can minimize internal leakage rate, 100% leakage testing.
Bi-directional flow, explosion-proof valve stem design, charging valve is available.
The valve body is equipped with bracket mounting holes for easy installation.
