Fig. 075 Lined Horizontal Poppet Check Valve
Poppet-Type Check Valves
Horizontal Check Valves are plastic-lined for handling corrosives and high-purity fluids. They are extremely effective in preventing back-pressure or backflow, featuring a low 0.5 psi (0.03 bar) cracking pressure differential, and are capable of handling pressures to 275 psi (19bar).
Since Tufline Check Valves have only one moving part, they are less likely to need maintenance. Because every surface in contact with fluid is made of, or covered with, a thick layer of plastic, corrosion and contamination are virtually eliminated. They also have full pipe diameter ports and provide minimal obstruction in the flow path. The poppet-type design eliminates problems that occur in some check valves with pockets that can trap fluid.
