Product DescriptionTechnical SpecificationsImage

The valve designation LAC stands for Low Ambient Control. Check valves are two-port valves having two openings in the body, one for fluid to enter and the other for fluid to leave. The valve is constructed using forged body and bonnet If the substance in the pipe flows in the opposite direction when the valve is closed, backflow occurs. These valves have elastomeric seal between seat & poppet. The flange drilling depends on the working pressure of the valve.
