Why ball valves and isolation help woth leak testing VRF systems... I installed 2 NDL Industries Inc. on each head on this VRF. Made locating a leak way easier than inspecting the entire system. #hvac #hvacr #hvaclife #refrigeration #hvacinstall #vrf #ductless #hvacsystem #refrigerationballvalves | HVAC Know It All

1. Ball Valve: A ball valve is a type of valve that uses a spherical ball with a hole or port in the middle to control the flow of fluid. The ball within the valve has a bore through which the fluid can pass when the valve is in the open position. By rotating the ball a quarter turn, the bore aligns with the pipe, allowing for unrestricted flow. When the ball is turned perpendicular to the pipe, the bore is blocked, shutting off the flow completely. Ball valves are known for their durability, re
